MSI announced five new additions

MSI announced five new additions


Today, MSI announced five dell laptop battery new additions to their Classic C-Series ultraportable line that bring some solid bang for your buck.

Cash-strapped gamers will appreciate the CX600 and CX700, both of which feature the ATi Mobility Radeon HD4330 discrete graphics card with 512 megabytes of video memory. The CX600 has a 16-inch 1366 by 768 pixel LCD display, while the CX700’s display weighs in at 17.3 inches with a laptop battery resolution of 1600 by 900 pixels.

People looking for a portable multimedia PC, however, will probably opt for one of the three new models in the CR line: the CR600-013 and CR600-017 use the same 16-inch display as the CX600, and the CR700 uses the same 17-inch display as the CX700. While the CR line’s NVIDIA GeForce 8200M G integrated graphics card isn’t nearly as powerful as the CX’s Radeon, the CR line has an HDMI port that lets you use any HDMI-capable display as a second dell INSPIRON 2600 battery monitor, which is particularly useful with the CR600-017’s Blu-ray optical drive (the other four laptops use a Super Multi Optical Drive).

All five of the laptops ship with Vista pre-installed, a 320GB Hard Disk Drive, 4GB of memory, Gigabit Ethernet, 802.11n Wi-Fi wireless networking, and a 6-cell battery, as well as laptop standards like a 1.3 Megapixel webcam, 4-in-1 card reader, and 3 USB ports. Each of the laptops is powered by an Intel T4200 Dual Core 2GHz processor, except the CR600-017, which has the T4300 2.1GHz. Models with the 16-inch screen will weigh 5.47lbs with the dell INSPIRON 2650 battery, while models with the 17-inch screen will weigh closer to 6.6lbs. There’s also a three-year warranty included to keep your new baby safe.

Best of all, the new C-series laptops start at a very reasonable $550. Stop by our $500-$1000 laptop chart to get an idea of what other companies are offering for that price, or check out our reviews of the MSI WIND U123 Netbook and the MSI GT 725 Desktop Replacement if you’re looking for more beef or more sleek.

Your humble blogwatcher has selected these bloggy morsels for your enjoyment.

Kasper Jade hears the whispers:

Once rumored for extinction, Apple’s entry-level polycarbonate MacBooks are on the verge of a refresh that will solidify them at the base of the dell 1G222 battery maker’s notebook offerings for the foreseeable future. … The 13-inch portables are presently undergoing an industrial design overhaul that will see them reemerge in the coming months with a slimmer, lighter enclosure and restructured internal architecture.

The white MacBook is outselling all other [portable] Macs. … Sales of the sub-$1000 system have remained surprisingly brisk amid the economic crunch, leaving management little choice but to allocate R&D expenses in its favor. … Apple is well-positioned to begin offering a model at considerable discount to the $999 entry-level model that exists today. MORE

Chris Foresman can’t resist:

The lonely white polycarbonate dell BAT3151L8 battery that still remains in Apple’s otherwise all-aluminum notebook lineup hasn’t changed significantly over the years. … Apple would likely use lower-end Core 2 Duo chips from Intel and could likely ditch the FireWire ports. We wouldn’t be surprised to see Apple dump the optical drive too, adding further cost and weight savings, nor would it be unusual if Apple designed in a non-removeable battery. (Heck, throw in a physically smaller screen, and you’d pretty much have yourself an Apple netbook.)

With nearly 60 percent of back-to-school shoppers looking to spend less than $750 on a new laptop, though, shaving a couple hundred bucks off the MacBook might make even more students and budget shoppers lean towards a Mac instead of a Windows- or Linux-based alternative. MORE

Harry McCracken joins in the fun , and even adds a car analogy:

It wouldn’t stun me if … Apple knocked $100 or so off the pricetag to make it into an upscale dell Latitude X300 battery alternative to a netbook. … Only a matter of time until Apple ships a non-Air MacBook with no DVD drive–in part to save money, in part to make the system thinner, and hey, maybe even to encourage consumption of movies and music from the iTunes store.

One thing I hope Apple doesn’t do is to give the white MacBook’s replacement an aluminum case. … I’m not so sure that plastic-clad notebooks don’t preserve their good looks better than their aluminum cousins, at least if you drop computers as often as I do. (Hey, I used to own a Saturn car, in part because of the plastic body.) MORE

Robert Evans speaks of “Consumer Ultra-Low Voltage” (CULV) devices:

Apple needs to get prices down substantially in order to make their notebooks more competitive with the variety of netbooks and CULVs that have come down the pipe as of late. Increasing battery life by a large margin is believed to be a major priority of Apple’s when it comes to redesigning the MacBook. It’s also likely that, by using last-generation processors and components, they will be able to cut down on costs dell W0465 battery while offering a solid boost in computing power over the last generation of MacBooks.

This recession has really changed up Apple’s game. They’re focusing less and less on high cost computers and gadgets, and more on affordable, reliable products for budget consumers. The $99 iPhone, the cost reduction for the MacBook Pro line, the revamping of the MacBook line, and the upcoming iTablet are all examples of this. MORE

Dieri Castrejon can’t wait:

I long for the return of glossy white in future Macs. Aluminum (as well as the combination of grey/black) seems too bleak & uber-industrial. Very Windows-esque. MORE

ten Experience of buying a laptop

ten Experience of buying a laptop


First: The most important thing: do not dell 8N544 battery easily change their laptop had been optimistic about the model and configuration! The reason is and read this paragraph if you fancy, and you before this configuration and price have asked a lot of dealers had. Because the notebook market, intense competition, basically you ask the dealer for a price, there is no profits. Then how should we do? Is very simple for you to change models, Imagine you run a day, and that model also asked about it, while the dealers through a variety of techniques allow you to buy another machine to see if the sky is also late, and he is running tired, do not want to run away, watching the salesman "good" in the eyes, about this paragraph is almost, well, not to ask, and she bought it, Oh, then you caught the. Because you do not understand this price, you can dell Inspiron 8600 battery imagine, after this transition from the profits generated is absolutely violence, and to use our jargon, there are at least 1000. If you really like on the salesman recommended the new, So to deal with this move is also very simple, no matter how sales staff to assure you that the price is the lowest of the. Must be pulled out of face and then ask the price, ask you know, what you are doing is absolutely valuable. Hehe. Eat a lot of powerful salesman embarrassed psychological prospective customers so that you embarrassed to walk out of his shop, then you yourself become the object of the slaughtered. If you are asked to go out and found that to you before the salesman to change models more reasonable price, then Congratulations, you have encountered a very rare honest salesman, but also waiting for? It is in this to buy bar.

Second: Ask prices also stress, if you started by asking about a machine model, for example, Asus A8, the A8 you just say the word, then you ask the price, most are very high . Because this case should be reported to high-priced salesman certainly, if you dell Inspiron 6400 battery say the price is too high, they will say that there are many models do, configure multi-part, I reported that the XX configuration, then you will impress the. The correct way of asking about the price: report a precise model, such as: A8H73SC-SL if you like a question, as a salesman, you know that you are very clear to understand, or do not report out of such a precise model, then the They also dare not offer a. So you ask the price is very real. There is no sense of chaos rather than the reported price.

Third: Do not suddenly asked to a very low heat to make you feel face heart bounce super-cheap but very excited, Oh, In fact, many sales staff is so dry, you buy this machine, right? Look at the price, oh, I be profitable, how can we do? Transition, ah, how to switch it? The first step is to let you report a ultra-low-cost, do you hear, ah happy, excited ah, such a low price, the salesman could not help but favor of doubling. Well, you optimistic about, he second, would certainly say that dell Inspiron E1505 battery before your eyes on how how that machine is not suitable for you, I now how this how you fit. Oh, remember Oh, if we really fancy his new recommended this paragraph, we must go out to ask a few, if you do not change your mind, do not waste your time and let him getting goods with it, mostly to take not come out, because he reported that the price is lower than the cost of newspapers are fundamentally not intend to sell it to you the results you have wasted valuable time, so my advice is: do not buy the lowest price of that one. You probably will harvest disappointed.

Fourth: for their bullish configuration must be understood. If you do not, then find understand (and fear of people afraid to do Budongzhuangdong staff, such a person most likely to be sold to settle the Sanxialiangxia members, and we must find really really understand dell GD761 battery the Renpei you) because the sales staff really knows how to use your configuration to Huyou do not know you, clearly that is the same machine, assert that what is more a separate graphics ah, or ah like what the dazzling screen, let you add money to buy. Such customers in my eyes is very tragic. I have seen for myself, laptop battery actually was brought alone to increase 2000 sales to sell, and do not know many computer users, after all, ah. If you have a clear configuration Seller of this move naturally useless.

Fifth: of course, to understand the machine you want to buy gifts, such as Asus have some time, S5 notebook computers equipped with a high version is free of charge to send a second battery, of course, if you do not know this information, sales staff will dell KD476 battery certainly be allows you to add a San Wubai to buy a second battery, did not say the. In fact, promotions like this, the simplest point, when the manufacturers do such promotions will certainly be related to color pages out to do publicity, you know the stage of a computer as long as the salesperson in mind to obtain a color page, the basic will not be in this trick on the. Of course, at home, some very large web site to find out, the better.

Sixth: The Many Friends of the Amoy when buying a notebook is very like to have a number of gifts, let me tell you, sales staff in offering free gifts, when only one principle: the cheapest. So, basically sent all are rubbish. Therefore, the most intelligent seller will first thing, and then an dell TD347 battery opportunity of talking salesman, I do not want these things, you give me less money, Oh, do not expect to lose salesman tell you that worth, that the value of the extent of how much money, basically, he said that what the value of 100 yuan, the cost of 30 yuan on the good. Can reduce how much depends on how you with the salesman about��

7th: Unfortunately, the manufacturers did not come to a kind of prototype of dealer-fat, so you can see the city in the computer prototype, all-new aircraft is to be sold. Of course, the prototype does not like most people imagine, it is very bad machine, in fact, we have for how to protect prototype, but the heart is used. That nasty a point of light-light, because the resulting prototype case because you scratch, you are given a sum of two hundred to paint. If you really do not want to dell Inspiron 1000 battery prototype, do not look at packaging, use, for some large businesses is that the seals were themselves printed. What does it look? Two things: First: look at interfaces of parts, such as network cards, is there into the dust, the new machine will not have gray. Second, a close look at the keyboard where the availability of dust, scratches the surface of the availability, especially in kinston keyhole, basically because taking into account the security, there must be locked, it will inevitably a little scratch. If there are scratches, you can determine is the prototype of the.

8th: Many salesmen say the vote is necessary to increase funding to develop, add a few points of several taxes, which is purely cheating, because the notebook computer when the purchase is a tax, and can not be an additional money. In addition, many sales staff would say, no warranty invoice, as long as the dell Inspiron 2200 battery receipt on it. This as an excuse not to give you an invoice is only a receipt. Indeed, the warranty, then the invoice can not guarantee. However, please note, there are still differences. If there is no invoice, warranty date is calculated according to the date of manufacture, there is an invoice, it is according to the invoice date to calculate the warranty date. The notebook computer inventory is very normal for two months, so imagine, if you are unfortunate in that two months when the machine is broken. . . There is another point; country has a law called the "three packs of micro-computer policy", which do three bags? Quality problems arise, seven days a caveat vendor, 15 days replacement within a year, after two maintenance still can not dell 312-0292 battery normally use, or replacement. The so-called three packs. And if you want to enjoy this three bags, that the premise is that you have to have an invoice. So why not give you develop salesman vote? Very pamphlets, non-profits can not afford early, he could sell in this part of your invoices to benefit from someone else. Therefore, the purchase of machine time, we must remember to obtain a copy of an invoice!

9th: It may say it so many people feel very difficult to believe, and Oh, but let me tell you, we used to that store, 15% of the profits, those who are taking kickbacks to help us create. So, if you ask an acquaintance to help you guard your computer dell laptop battery, remember the principle that you can: pull down the face, they have to separate out to ask the price. In this way, you will not be Huyou of. So, I do not quite willing to help an acquaintance to buy a computer, because I know that, I do not want to bear this infamy ah, my approach is: you out on my own first, ask price, then I will help you ask, so the price you have in mind at the end, it will not be afraid I will get a rebate��, Hehe. Oh, installed on regular basis to help a friend beat me Oh, the Xiong table. After all, the enthusiastic friends or the majority.

10th: is the conditional people buying a computer, I better go check the prices in major e-commerce sites, the most convenient is to go to Taobao investigation of price, it may Taobao prices in the stores not buy at the entity, if the reassuring words of can be bought online, it does not work, then go to shops to buy, at least the end of mind there will not be making too much, we all know that low prices Taobao laptop battery Well.

Solid-state hard drive technology in data

consider the Pacific Northwest National Laboratory using SSD products

In the Pacific Northwest dell laptop battery National Laboratory, solid state disk technology can alleviate the bottleneck effect of a supercomputer. In the laboratory, the experts to keep the write speed of 80Gbit per second and read speeds of

Second 136Gbit test. However, one or two slow hard drive will make the whole system performance decreased.

Pacific Northwest National Laboratory, a senior researcher Robert Farber said, "solid-state devices (such as flash drives) can use a RAID striping to achieve high-flow bandwidth,

Like a hard drive, like random access while maintaining a low response time. This is an exciting technologies. "

Laboratory have not yet switched solid-state technology. But Farber said the real debate is: For a limited range of search laptop battery applications, the low response time can ease the computing bandwidth access to the pressure

Force. This is not just an issue of price-capacity ratio. He said, "This is a consumer needs to bear the additional costs, because power supply, storage capacity and physical space with the previous

Magnetic media has a very different environment. "

In the Pacific Northwest Laboratory, their latest super-computer response time goal is to second 25Mbit. This is almost scientific NWChem software can manage this kind of data-intensive computing environments. New Lab

Solid-state technology is the key to solve the bottleneck laboratory.

Farber expect a breakthrough in the near future, the operating system will change its hierarchical storage system for direct access to the SSD, will this technology into a large storage capacity hard disk drive replacement

SSD for many users is a complementary technology rather than technology updates

Problems still exist: When the enterprise SSD can really affect? Some people say that the SSD adoption of data center has just begun, despite the notebook computers, such as the Dell XPS M1330 has been configured 3

Qualitative research, while the retailer may require a faster system of electronic cash registers.

Violin Memory Co., Ltd. is the industry's family is concerned about the company. The company's total to Terabyte storage device to the serial access and random access to provide more than 1Gbit per second access speed of

. SLAC's Mount, said he tested the Violin sample-based DRAM devices, while the Violin's forthcoming flash-based storage system looks like, and SLAC's application software is compatible.

Violin, a spokesman for the company explained that the company's two main bottleneck is the dell MM165 battery network computing speed and storage systems IOPS. He said that at present, sequence of operations per second, the disk speed of about 100Mbit, but the

For the amount of random access 4k data blocks, the speed per second is only 1Mbit.

Janukowicz added, "In some cases, the minimum storage capacity requirements are suitable for SSD. At the same time, high-performance applications, IOPS metric can be hard disk drives to support the SSD.

"However, even with these advantages, he said," IDC's survey of SSD have not completely replace the server hard drive. SSD does have a performance advantage, and is a "green" solution

Program. However, there are a lot of application software from the hard drive need to provide the dell YD626 battery storage capacity.

Enterprise Strategy Group, Peters said, the throughput requirements will lead to a gradual shift solid-state hard drive technology, but still takes time. He said, "From a technology is completely transferred to another technology to

Data center is rare. "

Flash memory has long been the introduction of the notebook is not a new idea, but because of high prices, the idea has not been a large-scale implementation. But now the picture was much different. With the flash memory SSD dell 312-0393 battery drive

The large-scale actuator continuing price cuts, as a notebook will be the main storage is no longer a fantasy. And the advantages of SSD drives are also in doubt, 80GB of SSD drives is only 59 grams

Heavy equipment, notebooks these drives are now available from Dell, Fujitsu, and Toshiba was purchased. However, consumers pay for this extra weight on the money, it is worth Mody? The most important thing is the performance, Is not it?

In a comparison test, SSD drive, compared with the traditional, and no special advantages, performance, or less. SSD drives only to find a file at random had shown remarkable strength. 6

And most people expect, SSD drives for notebooks bring longer periods of time in this fantasy, but also shattered. In our tests, the use of SSD drive, the notebook only than the use of mass

Laptop hard drive more unified 3 minutes dell Latitude D800 battery usage time.

Of course, not merely from the figure to illustrate the benefits of SSD. Will reduce the use of SSD notebook's internal moving parts, thus enhancing the notebook's mobility and stability. And the generated heat and SSD

Hard drives are also much less compared to electromagnetic pollution is also smaller.

Therefore, the long-term view, SSD Inside in the future you will be a good dell Inspiron 8500 battery choice.

Recovered a large number of untreated hazardous waste batteries great

With the social and economic development, various electronics and communications equipment in large numbers, replacement continues to accelerate dell laptop battery and make people use in their daily lives the number and types of batteries is increasing dramatically. According to incomplete statistics, China's lead-acid battery manufacturer, has reached around 1500, producing an average annual rate of about 20% of the high-speed growth. In 2007, China's battery production reached 33.7 billion, exports amounted to 25.168 billion, the battery output has exceeded more than half of world production.

Recovered a large number of untreated hazardous waste batteries great

Waste dell Inspiron 630m battery may be small, against Queshen big. China has become the production and consumption of battery power, so battery waste pollution is an urgent need to address a major environmental problem. Waste batteries are mainly harmful to the environment of harmful components of the cell after the pollution caused by discarded batteries. Batteries harmful ingredients are mainly mercury, cadmium, nickel, lead and heavy metals, in addition to acid, alkali and other electrolyte solution, harmful to human and ecological environment in varying degrees of harm. It is understood that, in which the environment on human health and ecological hazards greater control of the List of hazardous waste to include scrap batteries are: mercury batteries (primarily mercuric oxide batteries), lead-acid dell Inspiron 640m battery, cadmium batteries (mainly nickel-cadmium batteries ).

One of the environmental hazards of waste batteries

1.1 The types of batteries and harm

(1) zinc-manganese batteries

Zinc-manganese dry dell Y9943 battery of the hazards, which are mainly contained mercury and acid, alkali and other electrolyte solution was discarded into the environment of the possible harm caused. Heavy metals like mercury can cause central nervous system diseases, which Japan's "Minamata disease" culprit.

(2) button cell

Button-type zinc-silver dell RC107 battery are widely used in electronic watches, calculators, hearing aids and so on, is that people are more familiar with the battery variety. Such batteries are also mainly by the dangers of mercury, cadmium and silver hazards. According to statistics, a button battery produces harmful substances can contaminate 600,000 liters of water.

(3) lithium batteries

Lithium battery is used as anode materials for lithium batteries collectively referred to each series, including a battery and lithium metal, lithium-ion secondary battery. Because of its cost-effective, storage, long life, wide operating temperature range, etc., have been used in watches, cameras, calculators, back-up power supply, cardiac pacemakers, security alarm and so on. Type of battery against a relatively small, its recycling, recovery is mainly a useful component of lithium metal dell Latitude D620 battery.

(4) alkaline batteries

Alkaline batteries are zinc-silver, cadmium, nickel, iron, nickel, nickel-metal hydride battery series. Nickel-cadmium battery is currently the most widely used battery series, is also a focus on environmental issues as a dell PC764 battery, cadmium is highly toxic substances that are carcinogens, but also has the carcinogenicity of nickel, for aquatic organisms has obvious dangers. According to the U.S. EPA survey, discarded Ni-Cd battery of cadmium in municipal solid waste accounts for 75% of the total cadmium.

(5) lead-acid batteries

Lead-acid battery is the world's production of the largest and most widely used as a battery. Global battery sales account for more than 30% of sales. China's annual output of nearly 30 million lead-acid batteries kWh. Contamination of these batteries are mainly lead and heavy metals contamination of the electrolyte solution. Lead can cause nervous system neurasthenia, hand, foot and numbness, digestive system, indigestion, blood poisoning and kidney damage and other dell TD175 battery symptoms.

Flash memory has long been the introduction of the notebook is not a new idea, but because of high prices, the idea has not been a large-scale implementation. But now the picture was much different. With the flash memory SSD dell 312-0393 battery drive

The large-scale actuator continuing price cuts, as a notebook will be the main storage is no longer a fantasy. And the advantages of SSD drives are also in doubt, 80GB of SSD drives is only 59 grams

Heavy equipment, notebooks these drives are now available from Dell, Fujitsu, and Toshiba was purchased. However, consumers pay for this extra weight on the money, it is worth Mody? The most important thing is the performance, Is not it?

In a comparison test, SSD drive, compared with the traditional, and no special advantages, performance, or less. SSD drives only to find a file at random had shown remarkable strength. 6

And most people expect, SSD drives for notebooks bring longer periods of time in this fantasy, but also shattered. In our tests, the use of SSD drive, the notebook only than the use of mass

Laptop hard drive more unified 3 minutes dell Latitude D800 battery usage time.

Of course, not merely from the figure to illustrate the benefits of SSD. Will reduce the use of SSD notebook's internal moving parts, thus enhancing the notebook's mobility and stability. And the generated heat and SSD

Hard drives are also much less compared to electromagnetic pollution is also smaller.

Therefore, the long-term view, SSD Inside in the future you will be a good dell Inspiron 8500 battery choice.

6 errors of battery charging

6 errors of battery charging


laptop battery charging time to pay attention, in the end laptops is the correct amount of time to recharge, and in the process of charging only what is necessary to grasp? How many hours will it affect the laptop battery life? The following extensions on these issues open, take a look at the most vulnerable for the notebook notebook what could be attention.

Laptop Battery Charge Time

Misunderstanding 1: activation of a new dell laptop battery

A new battery charge and discharge cycles should be a way to activate the cell performance

Truth: This argument is not a rumor exactly. Because some laptop batteries from the product to the customer's hands will be after a certain time lag, the short is a month, as many as half a year. For longer battery life time difference, the electrode materials will be passive, so the manufacturer's suggested initial use of battery is best for 3 to 5 times fully charge and discharge processes in order to eliminate electrode materials passivation, to reach maximum capacity. However, here is the general charge and discharge is not a depth of discharge, but a shallow discharge, where there is a dell Inspiron 2500 battery charging time to grasp the problem.

Laptop batteries "before the three" charge

Misunderstanding 2: When a new battery buy it back later, people would generally say the best three times charge and discharge cycles, while the laptop battery discharge time should not exceed 12 hours in order to activate the battery maximum effectiveness.

Truth: Ni-MH battery in order to achieve the most perfect saturation, need to go through "complementary" and "trickle" process, this time, generally about 5 hours. At present, lithium-ion dell Latitude CPX battery, "constant", "constant voltage" charging feature is its deep-charge time control at 4 hours. Once filled, the battery's internal protection circuit will automatically stop charging, so this approach is unscientific and has no practical significance.

Some people have been tested with the mobile phone. Using the battery charger travel charger is full, the switch to Charger battery charger to confirm the degree of saturation. When he discovered Charger charger is still charging the battery, they think that the battery has not yet reached saturation. In fact, this lack of rigorous testing methods. The reason is that the indicator light is not detected dell Latitude C600 battery Charger saturated or not, the only true standard of reference voltage charger Charger cell phone does not necessarily mean reference voltage, so when the phone that the battery reached, Charger Charger may not think so, still charging, but is filled in, the only of its own know.

As long as the laptop battery charge time, discharge time to grasp properly, it is possible to reach the best state.

Misunderstanding 3: As long as rechargeable dell Latitude C610 battery used properly, it will, within a certain period of circulation appears best to achieve maximum capacity.

For example, the early nickel-metal hydride, nickel cadmium batteries, if used properly, regular maintenance, will be 15 to 203 cycles points to reach its maximum capacity (factory capacity 1200mAh Ni-MH battery in the loop 120 times, the capacity may be to 1200mAh).

Truth: It's a dell Latitude C640 battery in the Japanese products are more common technical specifications in its cyclical nature of the book can often be seen in Fig. However, the current mainstream of lithium-ion battery, this cycle peak phenomenon does not exist. Because the lithium-ion batteries from the factory to the scrap, with a capacity less performance for the circle time, never had the capacity rebound phenomenon. Maybe have a friend who will ask some ThinkPad notebook users through the deep discharge, you can restore the battery capacity. In fact it is only testing the software error detection only, the battery's actual capacity did not improve.

The right dell 1691P battery factor affecting the environment in which the temperature, of course, laptop charging time there is a certain relationship, but still inferior to the environment.

Lithium-ion batteries in the end there is no best state? The answer is yes, it suffered with the ambient temperature change. Under normal circumstances, lithium-ion batteries in 26 ℃ ~ 41 ℃ environment would show excellent performance. By low temperature or high-temperature state, its performance is being reduced. For example, according to your outdoors in direct sunlight using a laptop computer cases, there is no longer in the indoor use.

Misunderstanding four: two nominal capacity of the same (for example, 800mAh) dell 75UYF battery, if an actual measured capacity of 860mAh, the other is 805mAh, so 860mAH's definitely better than the 805mAh.

Truth: In general, different models (different sizes) and lithium-ion battery, the higher the capacity the longer the time used. If you set aside such factors as size and weight, of course, is the capacity the better. But for two nominal capacity of the same (for example, the example above) the battery may not be. Since the actual high capacity dell 5081P battery that is likely to add in the electrode materials used to increase the initial capacity of the material, reducing the stability of electrode materials used. The result is shown in dozens of cycles, after the rapid decay of high capacity piece, while the capacity is still low strong. Many domestic firms in order to reduce costs and expand sales, often on the use of such tools to produce high-capacity dell Inspiron 700m battery. Users will find that six months after the use of working time is much shorter. In short, to improve capacity at the expense of sacrificing cycle life, battery makers are not material up and down the article, it is impossible to truly improve the battery capacity.

Battery Save

Misunderstanding 5: If you do not use rechargeable dell Inspiron 710m battery, should shine of the electric re-save.

Truth: In fact, not only are the above-mentioned rumors, lithium-ion batteries in the end that was full of preserved or preserving the shine is sure to make a lot of people confused? Answer to this question from a congenital defect of their talk, that is "aging effect." Lithium-ion battery in storage for some time, even without the use of recycled some of its capacity will be a permanent loss, because the lithium-ion battery anode material from the factory is started when the failure of their journey. Different temperatures and the saturation level of the range is also different under the age of the specific range can be seen in the table below.

Thus, the higher the storage temperature, the battery charge of the more full, the greater the magnitude of capacity. So for long-term preservation of lithium ion dell F5136 battery, the user should be controlled at 40% of its electricity and stored at 15 ℃ or lower temperatures can be. For those nickel-metal hydride and nickel cadmium batteries did not exist in this "aging effect", after the long-term storage in just a few full charge and discharge can be restored to its original capacity of the follow-up full of electric charge.

Misunderstanding 6: laptop battery recharge time is generally controlled, for the laptop battery is full then, while continuing to charge the battery charge 1 to 2 hours, which would help to enhance dell 312-0306 battery saturation.

Truth: In fact, the notebook and laptop batteries are generally over power protection circuit, full of points, then he will automatically cut off the charging circuit. Therefore, charging time is fixed, full power only after the laptop power supply equipment, real-time re-charge the dell 312-0305 battery for 12 hours to no purpose.

Waste batteries pollute the water and soil

Waste batteries pollute the water and soil


1.2 Waste laptop battery of heavy metals in the migration of contaminants in the environment

Discarded nickel-cadmium batteries and mercury batteries and other hazardous substances into the environment has the will, after the corrosive effects of long-term damage, leading to heavy metals and acid-base electrolyte gradually leak out and pollute the environment, may directly or indirectly endanger people's health. Waste dell laptop battery of heavy metals pollutants in the environment, migration path, mainly used batteries into the municipal solid waste, with the domestic garbage into the landfill, incineration, composting process. China's current low level of landfill disposal, many of garbage piling up in a simple state, and used batteries of heavy metal contamination through leakage in the role of direct water and soil. Of heavy metals in soil and water ions will be the roots of plants to dell Inspiron 500m battery absorb, when the animals to eat plants, the body will accumulate heavy metals, after the food chain biomagnification of heavy metals in the human body will be enriched, in some organs of savings cause chronic poisoning, damage to the nervous system and liver function. In the incineration process, waste batteries of heavy metals will be volatile due to high temperatures have been taken away smoke into the air directly to the heavy metals enter the body through breathing.

2 Recycling of used batteries

2.1 The status of waste battery recycling

It is understood that China's current recovery rate of used dell Inspiron 510m battery less than 2%. Beijing battery scrap produced annually by nearly 6,000 tons, accounting for 0.15% of the total garbage. 1998 Beijing garbage collection centers established in each of battery scrap recycling to produce annual accounts for only 1.7% of waste batteries is far lower than developed countries, nearly 50% of the waste utilization. From May 1998, Shanghai started the recycling of waste batteries, recycling point is also increased year after year, has so far set up four or five thousand a battery recycling points, a total of more than 100 tons of recycling of waste batteries, but it produces every year about their compared to more than 3000 tons of waste is also a far cry from the battery.

The United States is in the pollution control legislation on waste the dell Inspiron 600m battery up to the smallest one country, not only established a sound battery recycling system, but also established a number of waste batteries treatment plant. The United States the largest battery recycling organizations RBRC, this is a non-profit non-governmental environmental agencies, "public education campaigns" and "Battery Recycling Program," is the RBRC two main tasks, and received more than 300 battery production sponsorship. RBRC has also established the United States and Canada more than 30,000 battery collection points, to recover the rechargeable dell Latitude D500 battery. Japan to engage in the largest waste battery recycling organization in Hokkaido Nomura Kosan Co., Ltd., its annual national recycling of used batteries from the 13,000 tons, accounting for Japan, 20% of the amount of waste batteries. Austria in 1967 on the establishment of a waste battery recycling system, recycling accounts for more than 80% of sales.

2.2 Waste management and recycling of batteries publicity and education

(1) increase the propaganda and education

In the battery recycling publicity and education, the EU proposed the dell Latitude D505 battery vendors, production and importers have the responsibility of educating the public, while the environmental protection department shall annually report to the implementation of the agreement then recovered. In addition to the U.S. Act provides for public education requirements, RBRC through television and radio public service announcement for battery recycling. However, there are pairs of used batteries recycling is very little publicity and education, the residents used batteries against lack of knowledge, there is no universal consciousness to form the collection, conscious awareness handed, so waste battery recycling is still difficult to create a scale, is not conducive to the waste cell to form industrial operations.

(2) for legislative and regulatory

The world's developed countries with low dell Latitude D510 battery production and disposal of mercury after the separation and recovery of the responsibilities of the legislative and regulatory. Germany in April 1998 promulgated the "waste dry batteries and battery recycling laws." Act on the battery design, production and sales made demands: to reduce mercury in alkaline manganese batteries; battery manufacturers must build on the battery contained in the recycling of hazardous materials disposal facilities; producers and distributors responsible for recycling all waste batteries and to the public for recycling publicity and education responsibilities, also asked manufacturers are required to pay the vendors and recycling old batteries for recycling and transport costs incurred. Japan Since 1986, asking to lower the production of mercury-containing batteries and a battery of mercury content, now prohibit the use of mercury in a battery. The United States in 1996 promulgated the "mercury batteries and rechargeable dell Latitude D520 battery Management Act," the legislation will require a phased ban on the use of mercury-containing batteries; establishment of an effective approach to recycling and processing nickel-cadmium batteries, lead acid batteries and other provisions of the battery; to educate the public concerned about the various types of waste battery collection, recycling and reasonable disposal; rechargeable batteries need to be affixed the appearance of uniform provisions of the label, the label shall be printed with "one shall be arbitrarily discarded batteries must be properly disposed of," the words. China is currently no specific law against the abolition of the battery, only a few industry-specific provisions.

(3) the establishment of recycling network system

RBRC battery recycling organizations, the United States used three ways to recycling of used batteries: First, retailers, retailers with RBRC agreement, RBRC for recycling used batteries costs and transportation costs, this is a simple and convenient way to recovery; two communities and recovery of public services, RBRC for recycling to the community on how information on household batteries, and provide free recycling containers and other materials; 3 is a commercial recycling, RBRC recycling operators to provide non-domestic portable information on rechargeable dell Latitude D600 battery, RBRC is responsible for all recovery costs, shippers are only responsible for transportation costs.

Japan in the "Renewable Support Act" defined the nickel-cadmium batteries and dry battery recycling by consumers to the regeneration of the three channels of business: By Category collected and forwarded by the local government to focus; from the battery vendors, manufacturers referred to. By matching the machine vendors and service center to transmit, thus improved the recovery of channels. In addition, the Japanese MITI launched a trial of various local government bodies dry separation and recovery to ensure that regeneration unit's needs.

In order to enhance the recovery of waste battery management, Germany implemented a battery recycling management of the new requirements. Provision requires that consumers will use the end of the dry dell Latitude D610 battery, button batteries and other types of batteries to the store or recycling waste recycling, shops and scrap recycling of waste batteries must be unconditional acceptance, and transferred to manufacturers for recycling processing.

China has yet to establish a comprehensive battery recycling system, and battery recycling is still difficult to pose a real problem. Even if the battery recall to face an embarrassing situation, because people do not know how to properly handle the waste batteries. China has so far not a professional, capable of batch processing of waste batteries enterprises across the country to collect used batteries in areas which are experiencing similar problems, resulting in many areas and departments can only be taken by stacking approach. Therefore, the formation of industrial waste dell 312-0068 battery treatment has become imperative.

2.3 a variety of waste battery recycling technology and its advantages and disadvantages

At present, waste battery recycling technology are mainly two kinds of wet and pyro-metallurgical approach. Hydrometallurgical waste battery recycling process is based on zinc, manganese, nickel, cadmium, lead, lithium, etc. can be dissolved in acid, the principle, the methods used to roasting - leaching and direct leaching. Wet and fire wears compared with less investment, low cost, factory speed, high-profit, technology flexibility and other advantages. Pyro-metallurgical processing of waste batteries, dry dell 6Y270 battery at high temperatures, so that the metals and their compounds, oxidation, reduction, decomposition and evaporation, condensation. Pyro-metallurgical method is divided into pressure and vacuum metallurgy. At present, Switzerland, Japan, Sweden, the United States and other countries are mainly used pyro-metallurgical processes, recycling of the fire method has high efficiency, no secondary pollution, the benefits, but the one-time investment, technological requirements and operating costs relatively high. To date, all waste battery recycling technology still can not guarantee 100% recovery of harmful ingredients.

3 Waste battery recycling policies and measures to be multi-pronged

Recycling of used dell 1X793 battery in China is not optimistic, very low recovery rate. According to relevant statistics, China's large and medium cities battery recovery rate is only about 2% of batteries sold, indicating the vast majority of batteries are still being arbitrarily discarded after use, and always in a polluted environment and endanger people's health. This phenomenon should be caused by the relevant departments and people's attention. At present, China's work to dispose of scrap batteries still in its initial stage, the urgent need to establish an effective recycling system and the system, but can take some practical methods and measures: first of all should be drawn up on the detailed rules of used dell C1295 battery recycling, recovery and non-recovery should be to reward or punishment, the relevant functional departments of the production enterprises, recycling sector, individuals make a targeted guidance. Second, we should step up publicity to raise public awareness of environmental responsibility, so that more and more people used batteries must be recycled to establish the concept and thus consciously involved in recycling activities. At present, measures should be taken for the recycling of used batteries to create a variety of facilities, to accelerate universal waste separation and recycling in all neighborhoods generally set up a special dell Inspiron 1100 battery recycling bins to promote waste separation and recovery measures, while improvement of existing recovery methods, such as trade-in, home care, increase the density of the establishment of recycling bins, so that people are willing to waste battery recycling. Third, the legislation provides for sales of batteries and implement mortgage payments system, the battery manufacturer in the factory, in every cell of the ex-factory price of the mortgage on the basis of certain withholding payments, this mortgage payment through subsequent layers of distribution channels the transfer of withholding, until the battery from the consumers to buy the ultimate responsibility. At the same time, the battery manufacturers need to be withholding payment transferred to the recovery of the mortgage sector, consumers will be when used batteries to the recycling sector, we can recover the purchase of prepaid cell when the mortgage payment. This makes the lack of internal value of used dell Inspiron 5100 battery under the premise of man-made externally generated interest in its mechanism to allow the recovery of used batteries to the final implementation.

4 Conclusion

Used batteries to the environment pollution problems are gradually attracted people's attention, scrap battery recycling, processing and utilization is a systematic project, people have been looking for technically feasible and economically desirable to the scientific approach. Harmless disposal of waste batteries and comprehensive utilization of the protection of the environment, saving resources is of great significance, is the power in the contemporary era will benefit future dell 6T473 battery generations of the feat

how to protect you battery

how to protect you battery


Should pay attention to the use of questions:

Battery is a "dell laptop battery consumables," the degree of damage depends on the battery when you use the battery for the correctness of the operation, the operation mode, operating frequency, the working environment temperature, storage time (for unused batteries), etc. Factor .

1. The battery charge and discharge frequency is directly related to battery life, in general the number of lithium battery charge and discharge of about only 400 ~ 600 times, improved product nothing but 800 times, each time the laptop battery charge on the end to the use of a step forward. (When the power of 85% or less of the battery charge, will be recorded and to increase the number of times on a single charge.)

To this end, when the battery voltage is greater than the battery-management process set starting value 96% charge, and your current place in which there is 220V AC power, they should make full use of AC power to minimize the number of battery charging to extend the the battery life.

At this point the battery do not have to remove from the machine because it will not start more than 96% of the electricity to recharge the battery. But even so, if you are a long-term use AC power and rarely used the dell G5260 battery, it is recommended, or remove the battery from the machine to compare the good, because the long-running laptop heat generated when the battery will cause some damage.

2. When the power is 3 ~ 5%, it should be timely to charge the battery, or battery self-discharge phenomenon will cause over-discharge and damage to the battery, charging the machine and may be shut down, suspend any other state, you can also charge while edge use.

Charging must be a full, otherwise it will damage the battery.

If charging machine at shutdown or hibernation, when the charge to 3 ~ 4 hours after the green power status indicators are no longer beating, the time has reached 100 percent capacity, it is timely removal of the AC power plug to prevent dell G5266 battery excess charge on the battery The damage the battery.

If charging machine was waiting, hang, or side with the state of charge while, then when the charge to 3 ~ 4 hours after the green power status indicators are no longer beating, the battery will automatically exit charge state.

Charging process will carry out a fast-charging, when the power status indicator light yellow (Chang-liang), filled to a certain a certain value into the thin trickle charge current is slow, when the power status indicator light flashes green the color becomes ; has been filled with 100%, after, it becomes green (Chang-liang) of the. Lithium battery charging process is the constant pressure dell Latitude CPi battery approach, and began charging voltage that will soon stabilize, while the current is getting smaller and smaller.

3. Power is not fully depleted before (ie electricity in the 5-100%), not to recharge the battery, otherwise it will shorten the battery life.

When the power is 5 ~ 95% battery should be used, so the use of AC power adapter will charge the battery (charging side by side state).

4. When the power is 96 ~ 100% or the battery removed from the machine can use the AC power adapter switched on, use the AC power adapter AC power adapter when you please put the DC output plug on the plug into the machine, and then AC power plug to plug it into 220V ~ socket; removed when the AC power adapter should be first, and then unplug the AC power plug from the machine, unplug the AC power adapter DC output plug. Otherwise, they might damage your equipment.

Using the AC power adapter, when the AC power plug to plug it into 220V ~ socket, while the power status indicator on the machine yet, gave the former (Note: During this period of about 5 seconds time), please press the power button to turn; dell Inspiron 8200 battery shutdown or go to sleep, in addition to green power status indicator lights have been extinguished all the other things, make a timely manner from 220V ~ unplug the AC power outlet plug, AC power plug pulled out after about 5 seconds, the green power status indicator light turns off ; (if necessary, may from time to unplug from the machine on AC power adapter's DC output plug, this time the battery will discharge through the AC power adapter reverse.) Otherwise the battery will overcharge and damage caused by the battery. Off state due to AC power adapter is still non-unloaded state, it will recharge the battery.

If the suspension of work in order to wait for the machine to enter, or suspend state, not from 220V ~ socket unplug the AC power plug; so when the machines still have the power to maintain. (Not recommended for a long time to make the dell Inspiron 8000 battery machine enters a wait or suspend state, in order to care for your machine.)

5. If the battery is a long time (several months) do not, we should start the machine remove the saved backup. Recommended that each one and a half or so once the battery discharge and charge order to improve the status of your battery to increase battery capacity.

6. If the battery is not a long time, it should be power set to 30 ~ 50% in stocks, it is recommended to charge the battery about once a year, and its capacity is set to 30 ~ 50%, to prevent over-discharge and damage to the battery. The battery is set to 30 ~ 50% of the specific operation method: When the battery power is greater than 50%, it can turn power to 30 ~ 50%. If the power consumption of less than 30%, then the first boot power to 3%, then recharge to 100% and then turn to 30 ~ 50% power consumption can be.

7. Do not put the battery temperature and a cold environment, the battery performance will be dell Inspiron 8100 battery temporarily reduced. Should be at standby mode to save battery life and storage of the state placed in places of lower temperature for the battery, the best temperature range is about 10 ~ 20 degrees Celsius.

8. With regard to the adjustment of charging start value

Charge starting value is set, click the system tray in the power plug icon (when you use the AC boot), or large white battery icon (when you use the battery at boot time) / select Improve Battery Health / modify the Start charging when below values.

Do not extend the charge cycle deliberately use substantially changed in battery management programs charge set start value; because when you charge a low start value set (for example, 80%), though with the battery using the AC dell Inspiron 4000 battery power adapter "charge with the cycle" may take up to three or four months, but if the battery when in use is bound to have to deal with their re-activate, otherwise the battery status and capacity of poor. This is in fact increased the number of charge cycles and shorten battery life. Furthermore, the battery every month and a half or so in need of a discharge and charge order, which is located due to charge a low start value (for example, 80%) after extended charging cycles will be more obvious with the meaningless.

After the battery is fully charged due to the phenomenon of self-discharge capacity fell to 96% generally last for about 50 days, while the battery every month and a half or so just in need of a discharge and charge order, it is apparent, IBM for us since pre-charge start value of 96% is not unreasonable. However, with the aging batteries, the battery is fully charged after the phenomenon of self-discharge of electricity dell Inspiron 4100 battery due to fall to 96% of the necessary time may be shortened, this time we have a need to charge slightly lower start value, so that the time just in one and a half months about.

how to choose a laptop

how to choose a laptop


Check carefully look to see if it dell laptop battery had not been demolished or is the collision before, whether the cracking of the Department, if we find this kind of problem, regardless of its price is not cheap to buy more. However, only some minor scratches, you can consider that this is because due to mobility needs, some small friction is inevitable. And the purchase of second-hand laptop depends on its thickness, size, weight, and similar comparison of second-hand laptop, take care who is who, according to their actual needs.

Step two: look closely and check your LCD screen

This is very important. As we all know, LCD is the most expensive notebook accessory components, accounting for the cost of the whole machine 20% ~ 35%, so choose should pay special attention to: 1, whether the injury marks on the screen because there are traces of the machine length time use, the refraction of light can seriously damage people's eyesight, believe it or move back to an impact of the machine vision laptop battery too worthwhile. 2, carefully observe the display size and display, the display screen size and price effects and linking to consider, of course, can be used to keep the prices down. 3, detailed identification of display colors. Observation of color apart from monitoring screen is 16 colors, 256 colors or 16, and 24-bit True Color True Color outside, but also placed at an angle both vertically and horizontally, in its observations, if the context in which that could be accurately regardless of the screen to see the color, can determine the true color. Otherwise, if we can only observe its front in order to identify the color, then it is pseudo-color. Can be hailed in the business, where a high-priced high-quality liquid crystal displays, and you want to buy it in a notebook next to the contrast in the same interface to their brightness, contrast and response speed, visibility and other parameters of the pros and cons. 4, note that monitor the performance and brightness of the delay. In dell Inspiron E1705 battery the selection of LCD monitors, the main fact is that it should be the length of the delay, if the delay time is too long, the eyes will feel tired. At the same time the brightness is an LCD display weakness, universal-type LCD's brightness will generally be in 200cd / ㎡ (lumens), below this brightness display on the desirable. There is not the time to see the brightness of a single look, look to tie in with the contrast adjustment. Some LCD monitors have the same brightness no matter how stressed a result, increase the contrast a very dazzling look very uncomfortable. In short in order to prevail eyes looked pretty comfortable. 5, pay attention to LCD screens dead pixels. The most common is the white point and black point, we use the following when buying a simple approach to identify: the identification of black spots in the general approach is to tune into the background of the entire screen black and white, then black spots on the general escape your eyes; white spots are just the opposite will be dell Inspiron 6000 battery (dell 6000 battery) the screen background to tune into the black, white spots at this time it will have Xianchuyuanxing啦! Nevertheless, except for white spots and black spots, and sometimes there are other color points, this time consumers were established three primary colors red, yellow, blue-screen background to identify a simple click.

Step Three: careful identification and testing of notebook components

Double-check notebook CPU, hard drives, memory and other components, buy the best you can when you open the machine to go and see. In addition, we must guard against the use of second-hand books of the profiteers CPU desktop replacement notebook CPU despicable practice. Since the same frequency of the CPU general users will not notice, but the use of desktop CPU and notebook CPU is totally different, due to heat different issues, making CPU issue comes in the notebook can not shed heat, resulting in system does not stable. So in the process of buying as much as possible on-site inspection request to the CPU. For hard drives, due to visual observation can not understand the pros and cons of the hard disk, and only be detected by means of software, testing dell Inspiron 9300 battery software available DM, NORTON and so on, through the DM, NORTON scanned, DM with a longer time, NORTON shorter time-consuming. Scanning process must be smooth uniform, if the cluster region which, when used too long, stating that the cluster region there must be problems. With regard to memory, second-hand laptop memory from 32M to 256M are, we should try to select more than 64M of memory, preferably more than 128M. Memory buy when to add a little, because some of the notebook computer's memory is rather special, and now long discontinued and can not reprovision. In addition, other houses, such as graphics card, we should also see a clear face to face.

Step four: Check the interface of second-hand laptop

Because there are no complete interface is very necessary. In today's notebook computers, with the popularization and application of external memory devices, USB interface, has become both desktop and notebook PCs an essential dell Inspiron 9400 battery device, USB port is very important to an interface. Therefore, the best to buy second-hand notebook computers have a USB interface. In addition, the infrared emission and reception capabilities of a laptop is now an essential feature. And, when buying second-hand laptop, there is an important condition is that the purchase of the machine depends on its power supply. External power supply is a must have, no battery is totally unacceptable and therefore also look at the main power supply is to see the battery is good or bad, that is, the length of battery usage time. Pairs of second-hand goods, the nickel-metal hydride batteries generally within one to two years can be used for one hour, lithium-ion batteries can be used for two hours, which is a basic requirement, otherwise we do not consider them.

Step five: Check peripheral status

View keyboard, mouse, CD-ROM, floppy drive, modem, etc. is available and easy to use. The last in the secondary market to see a second-hand laptop keyboard shiny, wear very serious, so no need to buy, and for the keyboard is necessary to block dell 310-6321 battery hundreds of pieces. At the same time to open a word processing software, to try every key on the keyboard is available, the mouse is flexible. Built-in floppy, CD-ROM, modem, etc. is available, please try one by one, as long as the equipment inside the computer can not be undetected!

Step six: to fight for second-hand merchant service
