Why laptop battery explode?

Laptop battery is composing of enclosure, interface, cell and control circuit board, battery cell is responsible for supplying and storing the power of the laptop. Control circuit board with complex working principle and design, it controls the battery start and stop charging at proper time, control the discharge current reasonable, and it also take charge of showing the battery capacity and recycle charge times recording. When the battery in a high temperature or large current and other un-normal condition, it the control circuit board can protect the battery.

The OEM post in http://www.laptops-battery.co.uk/

The four suspicion of laptop battery explosion.

A, Battery cells interior short-circuit

The Latitude D820 battery cells has no protection function when meet large current, if single or multiple cells happen short-circuit situation, it will let cells discharge at high current. These current generate large quantity of heats will let the battery enhance the temperature, and then transfer to the other parts of laptop.

If the Latitude D600 battery enclosure is plastic material, it will deform or even get fired under high temperature, it is dangerous. The regular cells has experience strict test when out from factory, and the battery enclosure always adopt fireproof material and difficult to get fire. So the most possibility is involved with poor quality material for VGP-BPS2C.

B, Battery cells connector wire short-circuit

The Dell Inspiron 6000 Battery, interior structure is too compact which leave opportunity for the cells. The wires in the middle are quite compact and close to the cells, if the skin of the cells and wires wore out, or the connect wires break off, then the cells will discharge at very high current and bring high temperature and cause fire final.

C, The control circuit invalidation

Sometimes, the control circuit will be invalidate for its protection part even it performed normal when use, when under full charge and un-normal, large current situation, the temperature will enhance and cause fire.

D Heat and abrupt incident

The laptop over heat or exterior liquid corrode, lightning strike or voltage un-normal will cause short-circuit.

How to measure the power consumption of notebook battery

The Original article posted in http://www.laptops-battery.co.uk/blog/

Why laptop battery capacity reduce as time? Why battery calibration can improv battery capacity? How to charge the battery correctly? All above probelm are related to battery power consumption. Open circuit voltage measurement ... ... Coulomb measurement, impedance measurement, what are these terms mean? Here we will simply introduce all of them!

Whether it is the out nickel-metal hydride batteries, lithium-ion Vostro 1310 battery , or not commonly used lithium polymer batteries, and even coming silver zinc batteries, are equivalent to the a storage warehouse of electronic power. The differences between them is that the way out of the Treasury, the volume of stocks it. In laptop batteries, there is a power manage center - power consumption chip, it is the management of power measuring, charging and discharging managing.

In the measurement of battery technology, there are four kinds common method (open-circuit voltage measurement, Coulomb calculation, impedance measurement, integrated look-up table method), but not all Vostro 1510 battery used only one method, usually using a combination of methods to one of the main method of supporting the rest of the way computing power. The first one is the open circuit voltage measurement, this method is that measuring the battery voltage under static values to calculate the remaining battery capacity, but as a result of stationary lithium-ion battery voltage and remaining capacity relation is non-linear, so this method measured valueis not accurate, the vast majority of mobile phone batteries are calculated using this method;

The second one is Coulomb calculation, the method is by measuring the Vostro 1520 battery charge and discharge current, the current value and time value After the calculation of product integration has been carried out by filling the battery into the power and the release of electricity, Coulomb's method is a accurate method of calculating power;

The third one is the impedance measurement, measuring its resistance to get the remaining battery capacity value; the fourth is a comprehensive look-up table method, by setting up a related form, the voltage, current, temperature and other parameters, you can query the remaining battery capacity.

Therefore, in addition to the internal structure of the battery batteries, there are control chips, the chip which contains 1-2 kinds of batteries power measurement method of calculation, and a charge-discharge protection circuit. Vostro 1710 battery manage program had been setted in the system, and through access to the chip-driven interface, and then set on the battery management.

So, why the dell vostro 1000 battery will become weak, but the battery calibration can improve the battery capacity? Notebook battery 6-cell and 4-cell, means that there are a number of battery cells inside the battery. The batteries cells conenect together, the battery capacity reduce reason is that: all the batteries quality and discharge rate can not be in the same level. After discharge, one battery cell capacity in substantial reduction, in order to maintain voltage stability, the battery management chip will be according protection of core power as the "bucket principle", so after the electricity charge will decrease.

Battery calibration is to balance the multiple batteries cells, the dell vostro 1500 battery cells own internal resistance can not be completely consistent, the large internal resistance battery will shoulder the larger current, and its own consumption more than the other batteries. So regular battery calibration is necessary - it can balance the burden of multiple batteries work and prolong the whole battery life.

Notebook Battery daily maintenance FAQ

Note that these steps correspond with decision points on the flowchart and are reached directly by clicking on the diamond symbols. The text below cannot be read sequentially.

Needs AC Adapter to boot? The first step in troubleshooting your inspiron e1705 battery is determining whether it can hold enough charge to boot the notebook. Will the laptop power up and run on the battery, or does the AC adapter which doubles as the laptop battery charger need to be plugged in? Modern notebooks usually have a whole array of status LEDs that will tell you if the laptop senses good power coming from the battery charger and whether or not the battery is charging. Unfortunately, there's no universal standard for these LEDs, their colors or their actions. Note also that we're using the term "boot" rather loosely here. If the laptop powers up on battery, you can hear the fans and the drives, your troubleshooting problem lies elsewhere.

Life Of Battery Too Short? This is the main problem laptop owners complain about, and often for good cause. Older laptops using Ni-Cad and early Ni-MH inspiron 6400 batteries often ran for 2.5 to 3.5 hours when brand new, but within a month or so, would barely keep the notebook powered up for an hour. Newer laptops using Ni-MH and Li-ION batteries are much better, often holding onto a three hour life through hundreds of charge and discharge cycles. The first line of defense against complaints about battery life by the manufacturers is always, "Did you charge and operate the battery according to the manual?" Unfortunately, different laptop manufacturers seem to disagree over how to best treat GD761 batteries of the same technology, and I wouldn't be surprised if the differences extend to different models from the same manufacturer.

If the laptop's Dell D610 battery life has been slowly degrading over time, it's probably operating more or less in accordance with plan, but if you find the operating life shortened by more than 15% or 20% within the first few months, there's probably something wrong. Batteries of all technologies can be "trained" to perform poorly through non-ideal usage patterns, but the Li-ION battery technology is pretty resistant, and as long as you run them all the way down once a month or so, you can probably prevent any serious charging memory issues.

Is Battery New? Purchasers of brand-new laptops are often surprised to find the battery is dead, or runs down very quickly. Even if the a1175 battery was fully charged when the laptop was boxed for shipment, that box may have been sitting in a warehouse for six months or a year before you purchased it in a store, more than enough time for a notebook battery to self discharge to an appreciable degree, even if it's not being drawn upon. If the battery isn't new, and you just received the laptop as a hand-me-down or purchased it second hand, there's no reason to expect that a short Ibook G4 battery life is due to anything other than an aged battery. You can try to recondition the battery (see the laptop manufacturer website for for software that may be available), but odds are the battery simply can't hold a charge the way it did when it was new.

User Condition Powerbook G4 Battery? Some manufacturers may condition the battery before installation in the laptop, others expect you to read the owners manual instructions and do it yourself in the first few days you own the laptop. The most general procedure is to charge the battery fully before use (leaving it on the AC battery charger overnight is best), and then to run exclusively on battery until the battery is discharged. Some brands suggest you run until the operating system warns of low battery life remaining, which could be anywhere from 10% to 3% remaining on standard settings. Others recommend that you run the laptop until it shuts itself down. This doesn't mean that you have to sit there working for three or four hours, you can run the Macbook Pro battery down over multiple sessions over multiple days. The important thing is not to plug the AC power adapter back in and start recharging the battery until it is completely run down. The condition process generally requires you to go through this cycle three times in a row.

Runs Always With aspire 3000 Battery? If the owners manual for your notebook suggests removing the battery when plugged in for prolonged periods, doing so may greatly prolong the battery life in terms of both charge cycles and years. Personally, I tend to be lazy and just leave the battery in all the time, despite the fact I almost always work plugged in. The battery life on the first couple Toshiba's I owned dropped down to a half hour or so of running time within a few months my buying them, so it may have been my fault. Li-ION Aspire 3000 batteries are much more friendly to poor power management habits, but you should run them down to empty once a month to keep them from developing a memory.

Battery conditioning means training the individual LCBTP03003 battery cells into a pattern of giving as much power as they can and accepting the largest charge that they can. It would take an advanced chemistry text and a person much smarter than I to describe the underlying reasons for battery memory, and the techniques for best charging and storing batteries sometimes contradict one another. Once a laptop battery pack is conditioned, you may still need to run it all the way down once a month for best performance, especially if you normally work with the laptop plugged in. It's important to read the owners manual section on battery life, because different models ship with different battery technologies, and the best practices to extend the battery life may not be the same.

Maximize your battery life

 

When I first got my laptop (8 mos. ago) my laptop battery life was about 2 hours 45. Now after daily use (mostly with plug but using battery as well) it is down to 1.5 hrs which is basically useless. I have tried draining totally recharging etc and still only 1.5 hours. SO I am buying a new one. My question is how do I make my battery keep its charge so I can have it when I need it?
I originally wanted to title this article "Why does my Ibook G4 14 battery life suck?", because I know that's exactly what it feels like when the battery life gets shorter and shorter. My oldest laptop has about a 20 minute lifespan, so in many ways the battery is really nothing more than a glorified UPS. Not that that's bad, but it does limit the laptop's portability.

I turned to a friend, Jerry Foutz, for some help on this one. Do a Google search for Power Supply Design, and Jerry's site, SMPS Technology, is the top result. Jerry knows power supplies.

It turns out that the single, most important aspect to maximizing battery life is something that I wouldn't have thought of: matching the battery to its charger. In Jerry's words: "Make sure your Ibook G4 12 battery and charger match and you have a quality charger. About the only way you can maximize the probability of this happening is to buy both from the computer manufacturer for the exact computer model."

"...even small differences in output voltage of the charger can have dramatic impact on the lifespan of your Dell laptop battery..."Apparently even small differences in output voltage of the charger can have dramatic impact on the lifespan of your battery, by either under, or over-charging. "If you get a low-cost charger and it is off by as little as 10 mV (millivolts, 1/1000 of a volt), you will also get less than optimum performance." An example Jerry shared is that a 4.1V cell charged at 4.050 V might be good for 4,000 charge cycles. Increasing the charge voltage to 4.250, a difference of less than 1/4 of a volt, can reduce this down to less than 100 cycles.

I had no idea that batteries were that sensitive.

I'm also glad that I've purchased my Toshiba PA3451U-1BRS batteries, extra batteries, and chargers from the manufacturer at the time I got my laptop. That, further, minimizes any manufacturing differences that may occur over time.

The number two factor in battery life? Temperature.

The fact is that laptops just aren't designed for ... well, for laps. If you look at the bottom of your laptop you'll see it probably has feet (or more likely, bumps or rubber pads) that lift it off of any flat surface you might put it on. That creates very important space for ventilation. If you block that space, with say your lap, it's likely that you'll be causing the laptop Inspiron E1705 battery to run hotter than it should. If you do this regularly, you'll likely shorten the lifespan of the laptop's batteries.

Again, in Jerry's words: "If you have your laptop on your lap and it is burning you, you are shorting the battery life and charge-cycle capability because you have interfered with its cooling system."

If you do like to use your laptop on your lap, there are various "laptop desks" out there that will provide you a flat, or even grooved surface (for even more space and air flow) on which to comfortably place your laptop Inspiron E1505 battery. My wife and I actually each have a laptop desk from LapWorks.

Temperature cycling - allowing the laptop Lenovo 40Y6799 to become very cold and then warm, repeatedly - say by leaving it in your car overnight in cold weather regularly can also adversely impact the battery's life.

A concern that I've had for a long time is whether or not leaving a laptop plugged in for extended periods of time would harm the Pavilion ZD7000 battery. Today's designs pretty much expect that type of usage, so it's not the issue I was afraid it might be. Good thing, too ... my laptop is plugged in and running pretty much 24x7.

Finally: "All this assumes a well designed power supply (including charger and Latitude C600 battery). Unfortunately, not all designs are perfect and the layman has almost no way to judge the quality of the design. You pretty much have to trust the manufacturer and his reputation."

The ThinkPad W701ds feels solidly built

ABSTRACT:Although Lenovo is at the heart of our most recent reliability survey laptops, the ThinkPad W701ds feels solidly built. We were impressed with the keyboard. The buttons are of decent size, but lack of resistance, so feel elastic when pressed. This makes it more likely typographical errors. The small pad is precise and its buttons well placed.

This simple two-button mouse-and-scroll includes high-speed mode for better track your movements. I have not noticed any difference with those settings, but the pointer feels lighter and generally a good hand. The track pad is missing 1691P, however. While the large surface feels great to move the cursor, 40y6795 includes a button to swing left and right-click. Push near the center, and you use a lot of pressure. Push in the center, and will not choose at all.

The screen has a problem with viewing angle. If the screen is not in the correct angle, this greatly affects the image quality. On the positive side, it dims the brightness when idle, saving HP dv4 Battery life laptop.

And with our new fastboot technology that provides ultra-fast startup time of just 30 seconds, you can use your PC anywhere, almost immediately. A generous 500GB of disk storage containing your favorite music, videos, and photos.

Although Lenovo is at the heart of our most recent reliability survey laptops, the ThinkPad W701ds feels solidly built. You'll have to lug the massive system of 8.97 pounds between large desks, but it's like bringing a powerful workstation almost everywhere. The IBM ThinkPad T60 Battery lasts about 2 hours, 10 minutes, a length reasonable for a laptop with this power and speed. Given this complete roster of car ports and extra content creators, including color calibrator, the surface Wacom tablet, and LCD extra-high-end laptop that looks equipped to help you complete any demanding job.

Compact, and less than 1 cm thick, the Asus (Asus A32-U5 battery) UL30Vt-A1 fits anywhere, freeing space for books, files, or whatever you need. The UL30Vt-A1 allows you to concentrate on the essentials of life. With this type of mobility, you get peace of mind you deserve.

Inside the netbook MSI Wind U210-075UK AMD is a new combination of central and graphics processors. The CPU is clocked at the same speed as most of Intel atom, but the MV-40 Neo Athlon helped MSI (Inspiron 9400 battery) to a WorldBench 6 speed score of 52 points. Compared with the results about-30-point Atom several machines, this is a healthy step-up.

The iPhone OS 4 upgrade includes a limited form of multitasking is more like fast switching application. It will not be able to view two applications side by side, and background activity will be limited to a small class of assets, such as listening to music, handling phone calls, buying a Inspiron 1300 Battery or updating position.

Solid as the graphics system is - I have not seen a snag when watching videos or doing some light export digital video - is the Core i5 and i7 processors in 15-in. and 17-in. models that buyers probably key in on. That's because they are relatively efficient to pack the punch, and even if they are dual-core chips, bring at least a touch of pseudo-quad-core to the top of Apple (Apple A1079 battery) 's line of laptops. Let me stress the word pseudo here: These are not the same chip quadcore true that the line of iMac desktop use.

The Dell (Dell Inspiron 1521 Battery) is Inspiron 15 15.6-inch LED backlight has a ratio of 16:9, which is nice for watching HD content. The screen is glossy in nature, have a good horizontal viewing angles, and it does a good job to display both text and film.

Another time tested Lenovo (IBM thinkpad x300 battery), strength is the keyboard, and the Lenovo IdeaPad S10-3 does not disappoint in this area either. The typing feel is good as it lies on a netbook, and there are crumpled or misplaced keys, Fujitsu and Asus. Using the Lenovo IdeaPad S10 Netbook-3 feels less like using a 10.1 incher any other netbook we've ever tried.

A Green Economy is in the end inevitable

The fourth annual meeting of the Business for Environment Global Summit (B4E) was attended by around 1,000 senior executives from some of the world's largest multinationals, including Coca-Cola, Dow Chemical, HP, Hitachi, LG Electronics, McKinsey & Co, Puma, Siemens,Sony VGP-BPS8 , and Virgin Group.

UN secretary-general Ban Ki-Moon said that he was looking to businesses to play a "major role" in efforts to tackle climate change.His comments were echoed by Achim Steiner, UN under-secretary-general and executive director of the UNEP, who warned that latitude d610 battery businesses could either take part in a well-managed transition to a low-carbon economy or face a rapid and potentially unplanned change in business models brought about by climate change and resource constraints.

"Thus a transition to a Green Economy is in the end inevitable. The question now is whether this happens by design or by default."The summit demonstrated that large numbers of firms now accept this argument and are exploring how best to develop new sustainable Dell C1295 batterybusiness models.

The message is clear: incorporating environmental, social and governance issues into business strategies and operations leads to long-range value creation for companies and societies. It is a winning formula for the global economy and our planet."

The ASUS Notebook series UL are the perfect balance between style and performance for mobile computing

Before the launch of the iPad, there were intense discussions whether it iPad would transform the market e-book upside down. In the U.S., users can download from Apple iPad iBook (A1008 battery) 's iTunes app store. Apple has not yet developed agreements with publishers in many other countries yet, so that the function will initially be absent when the iPad launches globally.

The new MacBook (Macbook Pro Series battery) Pro models still available in 13 -, 15 - and 17-inch varieties, with the same benefits as previous versions: a one-piece aluminum body for strength, lightness, and end-life recycling a glass touch pad that also acts as a two-button mouse, and beautiful LED backlit screens.

U200 speakers are reasonably strong, but the music sounds much muddy and there's little stereo separation. We recommend a pair of quality speakers or headphones for best sound quality possible.

Although benchmarks can give you an idea of how you stack against other computers, the activities of the real world are better on a computer to test. With this in mind, IBM 40y6797, I opened a file of 88 MB video in QuickTime and "chose the command" Save for Web This exports essentially the same video in different versions at the same time - and pegs the CPU while doing so.

The 17.3-inch screen, 1920-by-1080 pixels looks great in many situations. You can view more or spreadsheet are absorbed in games and movies. Text is clean and sports a range of brilliant colors. The contrast is good, but suffers at times under the surface slightly glossy, the laptop can handle a room bright enough, Presario R3000 Battery, but the reflections can overwhelm the image or outdoors near windows. The screen also does not tilt back quite far enough. You'll probably never have a problem with his corner on a desk, but you may wish for a bit 'thinner if it is perched on your lap.

But despite the six-cell Presario 1700 Battery bulk of our sample, the runtime netbook MSI Wind U210-075UK was a bit 'disappointing: just over three hours. For a similar sized U4873 battery on MSI Wind U100 netbook Atom, we used to see twice.

To be honest, is still among the best performances we've seen in laptops that are not ideally designed for the game. A special mention must be made of Webcams on R480. Used with the preloaded software Cyberlink YouCam, this webcam is much better to gather light in low light than many of its competitors. If you plan to extensively use video chat, mobile scores highly on this front.

The ASUS Notebook series UL are the perfect balance between style and performance for mobile computing. All are equipped with Ultra-Low-Voltage Intel ® Core ™ 2 Duo processor so you can enjoy the performance and long battery Asus A22-700 is necessary in the elegant models you need.

Not a powerful hardware configuration, although very good, however, for its target audience.

The Lenovo IdeaPad S10-3 for 8 hours, 27 minutes in our IBM ThinkPad X60 Battery tests, but his performance was bland to say the least. His score of 31 on WorldBench 6 is paragraph for a netbook, and feeling the global operating system Windows 7 starter system is slow. Part of the problem is that Lenovo (ThinkPad T42 Battery) has a habit of piling on background processes using the software that does nothing more than duplicate the existing functionality of Windows. The 5 ReadyComm network utility is an example. A few minutes with msconfig.exe and uninstalling unnecessary applications revived the machine on a lot.

The Sony Vaio VPC-F11J0E / H is a well featured laptop that can handle any and multi-task with ease

The latest crop of MacBook Pro laptops from Apple has several new features, such as a new generation of Intel processors, improved graphics and enhanced dual Apple MacBook Pro 15-inch battery life. Most of the changes, however, are relegated to 15in and 17in models. 13in models remain less expensive than the Pro line, but stay as close as the previous generation.

We like the new keyboard for the Dell Inspiron 15 - is much better than its predecessor. The keys are well defined, well-prepared and well packaged - very similar to what we saw on the Dell (Inspiron 1521 battery) your V13. With the Inspiron 15 is 15-inch form factor, has a full-sized keyboard with a dedicated numeric keypad on the right - similar to Acer Aspire 5740.

Unfortunately some of the weight savings were made by a small three-cell Inspiron E1705 battery handset. This means a limited duration rather moving little more than three hours (185 minutes), when extended from the MobileMark 2007 Productivity test.

Adding a color screen is another needs except apple a1036 adapter. End While reading the book, devices with black-and-white screens are unlikely to be a draw for readers - and publishers - newspapers and magazines are all gravitating who Toward the iPad. Color screens that use E Ink technology is not yet available but are under development.

keyboard keys are now flatter and more laminar, but there is a bit 'too much bending toward the center. We accept that if the MSI (PA3534U-1BRS) trackpad netbook Wind U210-075UK was more usable, is the least accurate input device that we had to work harder for a while.

Other titles include DirectShare, which synchronizes files and folders over the network, and OneKey Recovery, the pictures on your hard disk for disaster recovery - relatively boring, but useful, utility, although the latter program duplicates the functionality of Windows. Unfortunately, you also get Microsoft Works to perform basic tasks with Office. Most likely, Lenovo (IBM ThinkPad T40 Battery) feels the public will have its intended business productivity suite or activate the included 60 day trial of Office 2007.

Sony (VGP-BPS8 battery) VPC-VAIO F11J0E / H is a well featured laptop that can handle any and multi-task with ease. Its 16.4-inch screen and Blu-ray also make it one of the best portable media friendly around. If you intend to take our home or use only as a replacement for the Sony VAIO desktop VPC-F11J0E / H is a great, if not pricy proposition.

As for its performance, Sony (Sony PCGA-BP71 battery) VPC-EB1E0E/WI VAIO has an Intel Core i3 operates at 2.16 GHz which is great for everyday tasks like web browsing, email, documents and media . Last 7 Windows Home Premium Edition operating system also runs smoothly. Its 320 GB should be more than enough space to store music files and documents.

The cover attaches through different tabs Velcro is the insert liner and the main body of the same backpack. Once the liner in place, is pretty sure you will not have to worry about being pulled out of the moving components inside. SLAPP suggests this central pocket is large enough to handle gaming systems like Xbox 360, including power ibook g4 adapter supply, controller and games. This is fairly accurate, as the TARDIS, new form Slapp's system seems bigger inside than it is on the outside.

An immediate and obvious question must be whether the 13.1-inch screen offers enough real estate to work seriously. The answer really depends on the view as much as any other factor. The screen has a 16:9 aspect ratio,13 inch MacBook Pro Adapter, and to second iteration you choose comes with either a 900 or 1600 × 1920 × 1080 resolution. Our review sample had the highest resolution and while we were able to easily work with two documents open side by side, some people may find this resolution too squint inducing for comfort.

Apple launches new range of MacBook Pro news

They finally arrived on the market, after so much waiting, the MacBook Pro range of notebooks from Apple. And analyzing the models presented, it appears that the forecasts made by analysts about the performance capabilities of the new models have been very satisfied to A1079 and Apple iBook G4 14 inch Battery.
