laptop battery

Apple admitted that some laptop batteries are charging fault

Up to now, MacBook users have reported more than cell expansion events, the problem is mainly due to 17-inch MacBookPro ... ...

Li-ion battery Toshiba Satellite A75 Battery for iPod suspected quality problems caused by "explosive door" crisis is not resolved, but also cropped up more than laptop battery expansion events; just released to solve the problem battery performance software upgrade program, then there is the design flaw traced to notebooks. Apple continued turmoil in recent days, the flagship product ipod and laptop computer battery quality and widely questioned. This, industry sources told "Daily Economic News" interview analysis, a short time a series of similar quality problems, will likely lead consumers to a crisis of confidence on the Apple brand.

April 27, Apple has publicly admitted some of its MacBook and MacBookPro laptop battery charge failure may exist, and issued an upgrade program to improve battery Toshiba Satellite A70 Battery performance. Although Apple did emphasize the laptop battery charge arising from failure, "there is no security risk, users can continue using their batteries", but according to British media reports, MacBook battery issue is much more openness Apple more serious.

It is understood that, as of now, MacBook users have reported more than cell expansion events, the problem is mainly due to 17-inch MacBookPro. According to one of being a system administrator user is introduced to his research lab where an order for four 17-inch, using CoreDuo processors MacBookPro, of which three units have emerged in the course of deformation of the battery swelling. He said, MacBookPro expansion precursor of the battery occurred, MacBookPro, when using the battery-powered Toshiba Satellite A100 Battery random shutdown, but by the expansion of the battery pressure, sometimes manifested as reduced sensitivity trackpad.

MacBookPro battery due to expansion of the incident took place in foreign countries, so there are problems of a specific product model is currently unknown. The source told reporters that such a battery can be replaced free of charge, but there are potential hazards such as heat explosion, and noted that this problem is the software fixes can not be solved. In response, Apple's head of public relations while China maintains that, Apple has confirmed that there is no battery failure and security risks, consumers can continue to use, and said the battery maintenance plan is not equivalent to the previous battery Toshiba Satellite A10 Battery recall program.

The source said that in today's digital player market, Apple's share of the market share, whether Samsung, Sony, or innovation, Microsoft, can not hold a candle to. Prior to rivals also did not pose a serious challenge to Apple. But the iPod "blast door" after the incident, another series of laptop batteries burst expansion, design flaws and other issues, Apple's product quality will inevitably suffer some of the wavering of suspected users, and even Apple's brand loyal "fans" will also be right already have doubts about product quality. Coupled with respect is not yet on Apple's iPod "explosion" problem and notebook design flaw open to respond to, nor taken any substantive initiatives. Apple brand that consumers trust crisis, "may be only a matter Toshiba Portege 4000 Battery of time only."

Buy the best laptop to detect the battery half of those in sham

Dealers see the scene clearly break the seal machines, laptops Toshiba Satellite A65 Battery discovered after the results back to the battery charge is not into power, looking for distributors for a battery, problems remain, to the authoritative department detected a battery is a fake. Yesterday (3) days, the public is very depressed Mr Tsang told reporters that he did not know which part of an error, so that my original camera battery into "Li Gui."

In March of this year, Mr Tsang in Nanjing, a computer store to help the company purchased five sets brand laptops. To buy back later, another four camera was sent to the overseas branch offices. However, not long after, Mr Tsang on the Nanjing with this laptop on the emergence of strange things, the battery charge just 10 minutes, power indicator lights on the display is full of power, but connected to the battery, with less than 5 minutes, the camera automatically shut down because of no electricity, and Mr Tsang to determine the battery Toshiba Satellite A60-662 Battery is definitely a problem.

March 23, Mr Tsang was to find store counter, his face told the salesperson, the person himself, after a try, give Mr Tsang replaced a new battery, but returned after the two electric charge, this piece of the battery symptoms identical to the previous one.

Changed how usual it is also a problem? Mr. Tsang at this time cast doubts on the quality of the battery. March 25, John came to the brand battery designated testing organization, after the staff testing, confirmed that the battery is counterfeit products.

Dealer or soft sum of damages,
。 The dealers argued that he had never before moving packaging. Mr Tsang prepared on the matter when the complaints to the business sector, this dealer Huang Leshen, she immediately pulled to the side of Mr Tsang said that to "compounding." Mr. Xiang Zeng promised that she Toshiba Satellite 1900 Battery could give Mr Tsang replacement of the laptop battery, and do not need to test the premise of the report can also be another four camera battery replacement, and can be committed to this legislation to the writings of the battery is true. In order to compensate for the loss of Mr Tsang, dealers also willing to 2,000 yuan as compensation for mental damages.

The face of dealers "sincerity", Mr Tsang would also like to leave it alone, but he was somewhat puzzled, because it was obvious to see 5 sets his camera boxes are packaged good, but the battery was sealed packaging Yanyanshishi, What is the time the battery to , and I am still do not know. However, Mr Tsang said he hoped a good reporter to help him look into it.

Half of the professional inspection are false

Because the appearance is not easy to Toshiba Tecra 9100 Battery distinguish them, using relatively normal, so a lot of black-hearted merchants have been fighting the idea of fake mobile phone batteries. They use these fake batteries to back replace original battery, and then sell the original battery, you can make considerable profits.

"Basically, here detected more than half of all fake mobile phone batteries." A brand camera test center staff told reporters, laptop battery is indeed most likely to be "Diaobao" brand batteries and the general spread of counterfeit batteries to more than seven eight times, and some even higher. Brand manufacturers have also been fake, but the market is so huge inevitably "slip through the net."

One has done digital product owner, Wang told reporters, "Now the laptop market prices closer to costs, some vendors," Tsutsumiuchi loss Diwai fill "in the Toshiba Tecra 9000 Battery accessories on the relentless" slaughter "consumers, while some even direct for one of the parts. "For example, he said that with the Canon camera, for example, an ordinary genuine battery cost will be around 300 dollars, while the counterfeit Canon batteries need only tens of dollars, if the" Diaobao "successful, then earning more than selling more than a laptop.

Buy the best laptop to detect

"Counterfeit digital products accessories has been the focus of our efforts to combat the same time, the complaints in this area are indeed a lot." Nanjing industrial and commercial departments have told reporters that the price of digital products are now more Toshiba Tecra 8100 Battery and more transparent, a camera on the Internet can be quote found, compared to purchase price, usually a difference of no more than 50, a laptop to reduce machine profits has led some businesses to take the risk, so that consumers must learn to distinguish a certain knowledge.

"In general it will not matter a laptop, the problem is most camera with battery." The source said that the camera accessories businesses the means to make a big fuss on the variety, now sold on the market of laptops, batteries are manufacturing plants for the production of original equipment batteries. And an original laptop batteries are generally priced at 200 yuan to 300 yuan, the price is only tens of dollars on fake to 100 yuan. Although in the short-term use, and there is no significant difference, but the fake battery Toshiba Tecra 8000 Battery standby time significantly shorter than the original battery, and charge a very low life expectancy. How to avoid buying fake batteries, the person said, you can buy the camera when the monitoring point directly to the official, "verify its validity," Under normal circumstances professionals with the naked eye can distinguish

Notebook computer batteries and energy-saving

Read popular science books, learned through training in mice can be equipped with a roller cage running direction of North Korea carried out a power to provide Fujitsu FPCBP63 Battery electricity for the future society was very strange. However, this vision and the industry compared with the latest ideas, we should be much less. In order to get more laptop power supply support for a long time, the industry invented a patented technology: the keyboard charger.

Keyboard Chargers

Keyboard charger concept: magnet assembly of multiple keys on the keyboard, the power generation coil installed in the key seat, when a user tapping the keyboard, the magnet in the coil movement, resulting in induced current, these currents through the transformation with the to give the battery charge. Allegedly collected the energy of keystrokes can be battery life increased by 20% or more. To tell the joke, suggested that, in its installed on the notebook shell light bulbs, power Fujitsu FPCBP68 Battery failure or Zouye Lu someday when pounding the keyboard to lighting, this is the real way is called "flashlight."

Energy conservation is a requirement for notebooks

Not long ago, playing an old 386 laptop, which does not drive, there is no multi-media, of course not keep up with today's notebook computers fun, but one thing impressed me is its battery seems to be more durable. 386 computer Although there is no strong current computer 3D and multimedia capabilities, but word-processing needs energy consumption point of view, it will be much more energy-efficient. In all fairness, notebook computers are really not as easy to use desktop machines, we had used the laptop, because we lack a fixed sitting quietly in one place the conditions for office, so we want Fujitsu FPCBP77 Battery to move office, so our laptops are not for the completion of What 3D design and video production, nor is it used for playing some kind of three-dimensional simulation games are basically word processing, data and Internet access and other office uses, may not be a strong need for the latest CPU and 3D accelerator card, to know these two parts in Desktop machines are required cooling fan, which means they are energy-hungry. If you spend more time on the battery to maintain care, you are shopping for desktop PCs should consider these factors.

Nickel-metal hydride batteries and lithium batteries

At present the major use of two kinds of laptop batteries: Ni-MH battery Fujitsu FPCBP80 Battery and lithium batteries. Since there are two kinds of the battery market, of course, also have their own advantages and disadvantages. The most obvious one, that is, when buying cell phones, we have Gaode quite understand, that is, Ni-MH battery cheaper than lithium batteries, its negative side is the volume and weight are relatively larger. The characteristics of lithium batteries with them just the opposite. Because users prefer lighter, thinner, longer battery to maintain a notebook computer, so lithium batteries more popular pursuit of high-end products favored customers.

Charging Tips

Some notebook computers equipped with lithium batteries, using smart battery systems such as the SBS technology, accurate measurement of battery life, so use this to worry some. If you use nickel-metal hydride batteries, should be careful not to frequent over-charging, otherwise it will reduce the battery life, so a good control of charging time.

Ni-MH battery should be fully discharged before charging, the charge should be fully charged, use the methods and attention to issues with the use of cell phones nickel-metal hydride battery is the same. Buy a new nickel-metal hydride cell phone batteries, required to complete three complete charge and discharge after further normal use it, the laptop battery so should we.

Most users accustomed to using a laptop computer each time, plug the AC power supply, very little battery Toshiba Satellite 2100 Battery power for laptops. In fact, for at least a month should be used to power batteries once or twice, the battery completely run out, draw a line on a one-time full of alternating current. Remember this one: For the rechargeable battery for full charge with a dry, useful and harmless, but done a little trouble.

Accidents in the Mainland batteries battery factory pouring in Japan and South Korea favored supplier

The size of the global notebook PC market at an IBM ThinkPad T42 Battery annual rate of 25 ~ 30% of the growth of notebook computers have the supply chain works can look forward to glory in 2008, however, Japan and South Korea Department of battery factory fire accidents are frequent, with 10-inch below the 2008 low-cost PC supply high demand, many notebook computer plant started turning to the mainland of China battery factory, recently, including HP, Asus and other product lines divergent use of the mainland of China battery cell.

Since the 4th quarter of 2007, Japan, IBM ThinkPad T41 Battery South Korea Department of battery cell factory frequent accidents, so that notebook assembly plant and brand a big headache, but it also let the battery die factory in Mainland China given the opportunity, in the past a large number of Japanese battery factory recall Sony laptop Zengyin computer batteries, notebook computer market has started to make significant use of Korean-notebook computer batteries, battery cell factory in Mainland China is now taking advantage of the rise, began to receive attention.

Notebook computer industry pointed out that some of Asus Eee PC battery from the battery cell factory in Mainland China, Taiwan, Department of S & P also have to find a new battery IBM ThinkPad T40 Battery factory in Mainland China battery cell factory, and through HP's certification, will be first in HP's low-priced models use a paragraph, Ran quality problems are still not the effect that the notebook works, only a very small part of the low-end consumer products line of a trial.

Mainland China leading producer of batteries in Shenzhen, including BAK International (China Bak Battery) its wholly-owned subsidiary, Shenzhen BAK Battery (BAK), Amperex Technology Limited (ATL) and other battery cell factory, has been made in ASUS, HP certification, China battery Fujitsu FPCBP95 Battery cell factory in 2008 surfaced, the battery capacity is expected to make up part of the gap

Case study material Gaoding durability of thin and light notebooks

Many of my friends in the purchase notebook computers IBM 92P1060 Battery tend to focus only on the specific configuration of the book, while ignoring the notebook shell, in fact, this is a relatively large errors in the shell of notebook computers is our most accessible part of it important parts to play to protect the internal book, or even machine cooling effect. Therefore, the notebook shell also has an extremely important role and should be attention. Notebook computers are a common shell: ABS plastic, polycarbonate, carbon fiber, magnesium alloy, titanium alloy and so on several.

1, ABS engineering plastic

ABS engineering plastic that is IBM FRU 08K8193 Battery PC + ABS (plastic alloy), in the chemical industry of the Chinese name is plastic alloy, the reason named the PC + ABS, is used because it not only has excellent heat-resistant PC resin, weather resistance, dimensional stability and impact resistance , but also has excellent ABS resin processing mobility. Therefore, applications in thin-walled and complex shaped products, able to maintain its excellent performance, and the maintenance of plastic with a molding material composed of esters of. ABS engineering plastics is that the quality of the shortcomings of the best in the weight, poor thermal conductivity. In general, ABS engineering plastics due to low cost, by most notebook manufacturers to use, at present most of the plastic shell notebooks are based on the ABS IBM ThinkPad R51 Battery engineering plastic made of raw materials.

Xiao Bian's book is spent nearly 99 years to buy Da-Yuan 20000, when the consulting engineer's time, people told me that engineering plastics, and then kinda proud of it, do not think so ordinary plastic, but look at the existing arrangement, kinds of alloys of the book, really naive back then ah ~ ~ ~ ~

Polycarbonate polycarbonate shell notebook PC IBM ThinkPad R50 Battery is also a kind of material used in its raw material is oil, after processing of polyester chips plant after the particulate matter into polyester chips, and then processed by the plastics factory became a finished product, From a practical point of view, its thermal performance is also better than the ABS plastic, heat is more evenly dispersed, and its biggest drawback is more crisp, a down on the break.

The use of this material is more significant FUJITSU, and in many models are using this material, but for all shells have adopted such material. No matter from the surface or from the feeling of touch on, PC-GF-# # material feels like all metal. If the laptop has no identity, then do not see a single from the outer surface to observe carefully, you may think that the IBM ThinkPad T43 Battery alloy material.

Laptop battery should be prohibited on the plane

Recently, an explosion occurred in a matter notebook computer batteries IBM 92P1089 Battery, notebook batteries against people panic, the terrorists it can also be used as a weapon. So, why not just ban laptop batteries on the aircraft?

Notebook computer could be considered travel

Is the best things. It allows you to not delay the work, but also lets you play games on the road, watching movies to kill time. Even more remarkable was that many airlines invested heavily in Wi-Fi so that passengers can access in the air.

Can be, unfortunately, this laptop to give the "paradise" may not last too long, because the laptop will cause a catastrophic explosion. Past and present, the battery exploded when such things happen, no one can guarantee that it does not occur in the future, that is, the plane exploded only a matter of time.

Federal Aviation Administration (FAA) to prohibit the use of take-off iPod, why not just laptop batteries it is prohibited?

Let's take a look at laptop computer batteries IBM 92P1101 Battery caught fire What will the consequences.

Laptop batteries are usually in plastic or metal box, if a battery overheating, it will leak flammable liquid, and then an explosion, and caused a chain reaction in other cells. Temperature increased, notebooks will be hot out of a hole. As other batteries continue their explosive and incendiary, poisonous liquid can be left out of any one direction. These explosions and flames will be accompanied by acid and toxic fumes.

If you appear on a crowded plane a series of explosions, flames and toxic smoke, it's easy to panic. Passengers would have to leave the seat, towards the end of the aisle, blocking the road crew, so that they can not get the fire extinguisher on board the aircraft. Passengers rushed the front or rear aircraft may affect the pilot's weight and balance calculations. FAA also admitted that the flight IBM 08K8192 Battery crew to deal with fire incidents in the battery ill-prepared.

There is also a risk that terrorists could be a lot of laptop batteries on board aircraft, either directly on the laptop computer can also be placed inside the bag to do battery backup. During the flight, they can be together all of the laptop batteries, and then heated to cause explosions, fire, panic, and then, crash.

Now, FAA issued a new set of measures to prohibit the spare laptop battery in your checked luggage, in the hand luggage of the battery to accept a complex set of checks.

However, these provisions can not be avoided I have just mentioned laptop battery IBM 08K8193 Battery fire issue, especially in allowing the battery installed on the laptop computer case.

In addition, the laptop caught fire more from the inferior or problems caused by the battery. Airlines will never be able to check the battery's safety.

In my view, connected to the laptop computer batteries are more likely to cause accidents. If you are running together on the laptop, but it did not go into sleep mode, it is likely a computer package in an insulated heat up.

Another risk is that if put together a few batteries IBM 08K8195 Battery and other battery-fire will trigger a chain reaction explosion, in which case the temperature higher, more dangerous, more difficult to fight the fire.

Could it be that insisted until the laptop battery caught fire in flight, we would have the introduction of new regulations do? I think that the future of FAA may require the battery can not be installed on a laptop computer, but only on the plastic bags, and other cells can not be together. Although such a requirement than a total ban on in-flight use of laptop computers are much better, but still I have described would undermine the Wi-Fi laptop heaven.

So, someone invented a better battery IBM 08K8214 Battery before, to our security, often fly, best bar and so on.

With regard to the basic knowledge of battery

We have been charging for mobile phone batteries IBM 08K8199 Battery have different understanding of the use and maintenance, where I think we are all unified point of view and to correct some wrong views.
Talking about the lithium-ion batteries do, let's a brief look at the so-called lithium-ion batteries is to use can be hidden from the lithium-ion absorption of carbon materials as negative electrode active material of batteries, lithium-ion symbol Li-ion. As we all know batteries are normally as a positive, negative, diaphragm, electrolyte, and other basic elements, then the lithium-ion batteries used in these materials are generally the following substances:

Anode: lithium cobalt oxide (LiCoO2), lithium nickel (LiNiO2) lithium manganese oxide (LiMn 2 O 4), etc.;

Negative: artificial graphite series, series of natural graphite, coke, family, etc.;

Diaphragm: polyethylene (PE), polypropylene (PP) composed of single-or multi-layer micro-porous film;

Electrolyte: acetate propylene carbonate (PC), ethylene carbonate (EC), dimethyl carbonate (DMC), diethyl carbonate (DEC), methyl ethyl carbonate (MEC) composed of one dollar , binary or ternary mixture of

Sold on the market are mostly based on lithium-ion battery lithium cobalt oxide as cathode and graphite anode of the battery series.

The working mechanism of lithium-ion batteries laptop battery are: battery charging, the cathode material of lithium to form an ion leaching, embedded into the cathode-modified graphite layer; the battery discharges, the lithium-ion de-embedded from the graphite layer, through the separation membrane to the anode backfill lithium cobalt oxide layered structure. With lithium ion charging and discharging of the continuous positive and negative from the embedding and prolapse, so it was called "rocking chair cell" lithium-ion battery rated voltage of single 3.6V, charging limit voltage of 4.2V, discharge limit voltage to 2.5V.

Lithium-ion battery charging process is divided into two steps: first, constant current charging, the current is constant, voltage is going up, when the voltage to 4.2V when the charge is automatically converted to constant voltage charging, constant voltage charging at constant voltage, current is a smaller and smaller until the charge current is less than a pre-set value so far, so someone direct charge of the mobile phone when the battery charge clearly show is full grid of power, but still shows is charging, in fact, this time the voltage has reached Therefore, a 4.2V battery IBM 92P1073 Battery is displayed as full frame, then, is the constant voltage during the charging process, then someone may ask, why a constant voltage charging it directly to 4.2V with constant current charge is not on the list do, in fact, very easy explained that, because each cell has a certain amount of resistance, when carried out using constant current charge to 4.2V, when the 4.2V is actually not the actual battery voltage, but the battery voltage plus the voltage of the battery internal resistance on the consumption of the sum, if the current is large then the internal resistance of the voltage on the consumption also big, so it is the actual battery voltage is much smaller than 4.2V, so use constant voltage charging process, the charging current slowly down , so that the actual battery voltage is very close to 4.2V.

We use lithium-ion battery IBM 92P1077 Battery in the process actually does not need to know so much, we just know how to charge, how to discharge, how to use in order to maximize battery role and maintain a good cycling performance. Next, I will talk about in this regard some of my views:

1. The best is to use lithium-ion battery charger original, otherwise they will be a certain degree of damage to cells and affect their life;

2. Charger and Charger for the direct question, I think, if time permitted, it is better to use Charger, then it can extend battery life and also can increase the capacity of a single charge;

3. If the battery does not use a long time, it is best to charge into about 40% of the electricity in the 10 ~ 30 ℃ of temperature preservation, and every six months or so make up a battery;

4. For just bought a new battery, it was said that the first three charge must be charge 10 hours for the full activation of the battery, I think it is not necessary, of course, is for the new battery than the previous capacity of the future to be reduced, It was a long-term battery storage, caused by surface passivation active substances, I think the previous charge with the Charger IBM 92P1102 Battery to charge one or two hours after the green light is sufficient, of course, charging time depends on your charger and your battery charge current there will be changes in the different capacity, in short, the longer the charging time is not good, so not only can not activate the battery, on the contrary will affect the life, the worst case (if your charger voltage accuracy control is not enough) will be an explosion.

5. In the process of long-term use the battery often and have an understanding of the errors, I need to talk with you, we tend to believe that the battery usage is a certainty, for example 500 times, So every time the full utilization of So we asked every charge must be filled with as much as possible, every discharge it to be clean and put as much as possible, it seems that such use is the most efficient use of, in fact not the case, the battery life with your use of the existence of a certain relationship, If your battery IBM 08K8196 Battery cycle life is 500 times, if you're used properly, then perhaps it can use 700 to 800 times, so that the correct way is to use the charge should not charge too full, about 90% is enough, in the course of to see lower power consumption, we can immediately charge, rather than wait until it automatically shut down or even shut down automatically after the charge is not carried out, and we have done this in the lab experiment: 80% DOD of the battery life of more than 100% DOD's long battery life by about 30%;

6. It is also very important, lithium-ion batteries on the charger requirements are very strict limits for the charging voltage is very strict, you have to look at its requirements are 4.1V or 4.2V, because when the graphite anode used in series, then the limit When voltage is 4.2V, if the negative electrode using a series of coke, then it limits the voltage is 4.1V, the battery on this general description will be short, and battery charger must be matched, you can not use the charger to charge 4.2V to 4.1V battery;

7. It must also be emphasized: Absolutely not use rechargeable nickel-metal hydride batteries, or nickel-chrome battery DELL 08K8194 Battery charger rechargeable lithium-ion battery, so that will not only damage the battery and has the potential to explode;

8. Lithium-ion battery with no memory feature, so every time unlike the Ni-MH rechargeable batteries and nickel-chromium batteries need to discharge the same, it can conduct charge and discharge at any time.

In general, do not blind faith in the first IBM 92P1087 Battery three 12-hour charge, and do not always afraid and gave intentional discharge, as long as possible is to run out of charge, full use, not to emphasize too much of what the cell phone battery life is very long, Otherwise, self-defeating.

With the Device Manager can also be energy-saving

Do not know if you paid attention to not, for the laptop, its battery laptop battery state when used are generally there is no network, there is not much a state of external devices. For electrical appliances, anything running in the device, but it should be the use of electricity. Just like 600 years ago, pulling the ship inside the livestock, livestock is also a must eat to drink. But if we do not have access to this device, so that power consumption of the device in vain affect other brothers and sisters in the use of time, of course, is not desirable. Therefore, to get rid of. Of course, here to say get rid of is not a rip, but only temporarily disabled.

Set up and that would be fairly simple, in the Device Manager found the equipment it needs to do, and then right-disabled enough. Such as card readers, CD-ROM, 1394, network card, wireless card, etc. In any case, do not get rid of all. A world in IBM ThinkPad R32 Battery peace, and use of time can get about 10min to upgrade.

In addition, we believe that at this stage processor and WINDOWS system still has a BUG when the laptop battery under the state is best not to use an external USB and other peripherals. Prior to the study of this issue we also reported: external devices can cause mobile processor can not enter deep sleep power-saving state, the processor will maintain a relatively high frequency to consume precious power. Although later released a patch, but it does not seem to attract people's attention.

We believe that the power peripherals to their needs be more. We know that most of the wired mouse are not energy-saving features, and the use of power from the books in all. Therefore, the mouse ah, U disk ah sort of peripherals, the best is not to use, if you want to use, rapid Nong Wan, and then pull down IBM ThinkPad R40 Battery enough.

Computer screen brightness, the notebook makers have for us ready to FN add shortcut keys to adjust quickly. Of course, a very lazy in the hands of individual users, such as Xiaobian such people, some notebook also comes with a photosensitive element, automatically detects the surrounding light intensity, adjusted to a suitable brightness to save energy, take the opportunity to protect the eye. For example before the evaluation off on the seven-AW5500 have such functionality.

When the ambient light changes, they can effectively help you adjust the screen brightness to reduce power consumption and your eyes.

You see, it's that the recipe for half an hour's IBM 92P1075 Battery use of time so squeezed out. It seems the famous words of Mr. Lu Xun is still very right!
Energy saving in progress .....

Read the above so much, I think we should have a clearer notebook power-saving awareness. Finally Xiao Bian here or to conduct a summation.

One, buy this time, try to pick classes Centrino notebooks and the adoption of dynamic adjustment of voltage frequency processor notebooks. For example: Intel Celeron mobile processor, the non-respect, it is better PM, Core, Core 2 Duo.

2, buy this time try to pick a mainstream price, great brand support is not virtual, you look at the power management software functionality will know how to choose a.

3, the installation system, for the first time boot after the most energy-efficient power management settings can be ready to waste after the re-changed. A dedicated IBM 08K8197 Battery power management software must be installed on the laptop, the system can be preset settings let you get a good battery life results. Not have a dedicated power management notebook, be sure to take advantage of the system built-in power management projects.

4, battery condition, fewer peripherals; useless as far as possible the hardware is disabled.

5, in order to save energy, protect eyesight, it is recommended to adjust screen brightness on an appropriate, high brightness of the eyes not good. If you need to extend the use of laptops, the screen brightness can be transferred to the low-grade.

So that more IBM 08K8198 Battery power to be stronger the storm bar.

In fact, the energy saving is a need to adhere to things. In addition to extend notebook battery life time, and if you are using a direct current can also be used when such a setting, it is not also a province of the country for the people out a little bit of energy? A person may be more insignificant, but the power of a group of people can not be a small glimpse of the! Xiao Bian personally think that such an energy shortage in the present era, a little more trouble to save quite a bit of resources is good overall.

Crazy Test! A stroke recovery of used batteries can power? (b)

1. Experiment only for lithium batteries and nickel batteries, other batteries would be invalid

2. Experiment requires special attention to the battery laptop battery moisture treatment, in order to avoid moisture induced problems.

3. In the freezer test after the battery needs to be put it aside for a period of time (2-3 days), to prevent corrosion of the circuit drops its internal condensation.

In conclusion, several of the above caveats, we found two "aging" of the cell phone batteries, ready to be tested. This two battery battery performance than in the past have gone up substantially decreased an average of half a day of standby time (4-6 hours) or so.

■ real

Next, we started this experiment two batteries, first of all, we have packaged these two batteries.

Thick layers of newspapers on the packaging

Reuse plastic bags, IBM FRU 92P1167 Battery seal them, to avoid entering water
Next, we put it in the fridge freezer room, began a two-day wait.
Two days later, we have the battery removed and replaced with a package of newspapers, in the process of replacing the battery does the surface of a number of water droplets condensed, be erased, we are once again a good battery pack with newspaper, put it aside at room temperature .

And waited for two days, we began to separate these two battery charging. From the charging time point of view, this two batteries and an ordinary battery, and there is not much difference.
Results

In the charge wires, we were placed in these two cell phones to conduct the actual performance of the battery of tests.
In the test, a battery life and experimental ago and did not change much, still can only stand 3-4 hours, while at full power state to answer IBM ThinkPad X60 Battery the phone, there is still power shortages, forced the shutdown phenomenon.
While a battery, change is more obvious in the case of normal use, reaching about 2 days use of time (at night is not shut down), in which the amount of roughly 30 text messages, while the talk time in 50 minutes about.
The same testing process, the same aging batteries, why test results are will be completely different? The power to restore the battery, but also because of what the principles of the resumption of power it?
■ Battery principle analysis

Similarly, here we lithium battery, for example, first explain how it works.

Simply put, lithium-ion battery IBM 02K7039 Battery cathode material of lithium active compounds are usually composed of negative electrode is a special molecular structure of carbon. Common cathode material for the major components of LiCoO2, charging, added to the battery positive pole of the electric potential to force the release of compounds, lithium ion, embedded negative elements arranged in lamellar structure of the carbon. Discharge, lithium-ion from the lamellar structure of carbon precipitation and re-cathode combination of compounds. Lithium-ion movement generated a current.

Specifically, lithium-ion battery as a chemical power source, refer to two separate and de-embedding can be reversibly lithium intercalation compounds as positive and negative ion secondary battery constituted. When the battery is charging, the lithium-ion from the cathode in the de-embedded, embedded in the cathode, discharge the contrary. Lithium-ion battery IBM 02K6620 Battery is physics, materials science and chemistry of the crystallization of interdisciplinary research. Lithium-ion batteries involved in the physical mechanism, is currently being embedded in solid-state physics to explain the physical, the embedding (intercalation) is movable object particles (molecules, atoms, ions) reversible embedded in the main body with the right size of the lattice The network space point. Electron transport lithium-ion battery cathode and anode materials are mixed ionic and electronic conductor embedded compound. Electronics can only be positive and negative material movement. Embedded in a wide range of known compounds, object particles can be molecules, atoms or ions. In the embedded ions, requested by the main structure for charge compensation in order to maintain electrical neutrality. Charge compensation can be the main material can be achieved with changes in the structure, electrical conductivity before and after the embedded subject to change. Lithium-ion battery electrode materials can exist stably in the air is closely related with this feature. Intercalation compound only to meet the structural changes in reversible and are able to change the structure in order to compensate for the charge, as lithium-ion battery IBM 02K6928 Battery electrode materials.

Crazy Test! A stroke recovery of used batteries can power? (a)

■ Battery aging how to do?

Has now entered the digital era, we use more and more IBM FRU 92P1121 Battery electronic products. Did not say anything else, the past few years, mobile phones, digital cameras, PDA, MP3, etc. have already come into our lives. For a digital product, determine whether it is the standards of excellence is not only to look at its performance and appearance, and its battery life have become more user attention.

Used in a long time, we will find that, regardless of camera or mobile phone, the battery usage time is becoming shorter and shorter, cell phone batteries in these products is particularly evident, since most cell phone users every day during the normal work in the use of 1-2 years, many batteries are aging, and even the battery had just filled, then one or two phone automatically IBM FRU 92P1125 Battery shuts down.

These phenomena troubled a lot of users, is well known that an original battery can be described as valuable, and if the purchase of domestic battery life is even more can not be guaranteed.

But there are also a lot of friends interested in battery research, recent Xiaobian on the network to see a claim to "restore" the aging battery means in the end this way what is it?

■ Fun Web rumors starting

When your mobile phone battery IBM 40Y6793 Battery time shorter (memory effects or aging), you would buy a battery to replace it?

Next time you encounter this situation when you save your money, tell you a very effective way to give it a try.

1. To the battery with a newspaper (or paper towel) wrapped in plastic wrapping before being placed in a good three days into the freezer (newspapers can absorb excess moisture)

2. Three days later delegated two days out at room temperature (to avoid internal condensation droplets corrosion circuit)

3. Two days after the battery IBM ThinkPad Z61t Battery charge, charge mobile phone saturation, yellow wrap test (estimated to save 80% -90%)

This information revealed by the well-known battery manufacturers engineers and tested to be effective, anyway, everyone has the refrigerator, you will try it! (Please disseminate widely to the benefit of all Members)
These are Xiaobian see in a forum post, the content looks Xie Hu, for the success of this method, Xiaobian not very good judge, after all, we know that the principle of lithium batteries from the point of view, the battery capacity The failure is not reversible.
However, coincidentally, in the Xiaobian when browsing another forum, also encountered almost the same content, it seems the scope of this method is still very popular. So, this "method" Can we really restore the battery power it? This Xiaobian also created some interest, after all, there are also some close to home, "end" of the battery IBM ThinkPad Z60t Battery, brought to try, will not lose any.
