The notebook appears, the market was something called a mobile PC, mobile PC is no different in appearance with the average notebook, but these mobile PC battery, and thus become a truly mobile PC. Has been successively the definition of the notebook itself is explored, what accessories is the notebook of the flag, the processor? Mobile chipset? The example above, a good answer to that is to give the notebook to the continuation of life - the battery.
It is difficult to imagine when you can not boot even with a laptop, notebook. In such cases, it is estimated that many people will say: "leave power step will not work, this is also called the notebook?" This means with the above is basically the same. We usually use very few would have thought the laptop battery, because it was too small, tiny to you usually do not ignore its existence, but one day a sudden power outage, while the laptop is still lit, you'll want: "This laptop is really The good. "In fact, laptop or notebook, just this time of the battery to play its true role, people feel the truly bring the convenience of the laptop. Above that so much nonsense to say in fact that, no battery, no laptop, I am talking about is a conceptualized view, rather than that the laptop to leave the battery useless; Rather, leave the battery, the notebook is lost its most important characteristic - mobile and continuity. We all know now, the laptop can be drawn to a heavy battery and notebook batteries are lithium batteries. The historical Why lithium abandoning the other? From early to say, early on, the battery we use is called a nickel-chromium batteries, nickel cadmium NI-CD battery, although give the notebook a duration, but it has many shortcomings of headache, such as: bulky, heavy weight, small capacity, short life, the memory effect, etc. (nothing), of course, is no longer used. And nickel-metal hydride battery, this battery is also the battery industry, be active in, compared to other batteries, nickel metal hydride batteries to be more environmentally friendly, and also by far the most environmentally friendly battery, but the volume of the nickel-metal hydride battery itself does not make many thin and light machine satisfaction. In the lithium battery, small size, light weight, large capacity, low memory effect, charging time is short and the advantages of lithium batteries, all of a sudden rage, all mobile basic design quickly popularized the lithium battery, which not only in the field notebook, digital camera, MP3 and mobile phone, etc., need to use the laptop battery of basic products also became a lithium battery. However, the environmental protection of lithium batteries from time to nickel-metal hydride batteries, lithium batteries to discard will cause environmental pollution. May be present on the lithium battery has been misunderstanding that lithium batteries no memory, in fact, lithium is not memory, but memory is relatively small, it seems not very obvious. And lithium can be divided into two kinds of lithium and lithium-ion battery. Lithium there is a long time ago, it is not safe when used, often in charge when burning, bursting, perhaps because the elements are too active, lithium's sake. Then there is the improved lithium-ion battery, can inhibit the active ingredient lithium element, so that lithium really achieve safe, efficient, convenient, and the old lithium will be eliminated. As to how to distinguish them, able to identify from the label of the battery, lithium battery for the LI, lithium-ion battery is LI-ION. Another difference is that lithium and nickel-metal hydride battery charge cycles, the number of general lithium rechargeable only 400-600 times, specially modified products, but 800 times, and the general use of scrapped two years, and this is why the general notebook The vendors just take the battery 1 year package repair, and even some only six months warranty, even if the brand is also true. S relative to the number of lithium batteries, nickel metal hydride rechargeable batteries and more, is generally more than 700 times, good quality battery can charge and discharge of 1200, nickel-metal hydride battery life longer than lithium batteries. Just the same volume of Ni-MH battery power is not enough to satisfy the needs of the notebook now. Dismantling notebook lithium batteries in here to see the specific structure of the battery, so we reproduced in a dismantling of a foreign Dell laptop, in fact, if we really want to look at and even touch some. Is recommended when visiting second-hand notebook market, places to see, to repair the battery is definitely gain a lot.

Let us look at the Dell Computer to the newer lithium battery boxes, battery box has been damaged, and identifies the portion of the battery, we can see that the battery specifications 14.8v 3600mAh capacity.

In general, the battery seams are glued together by adhesive, so it is easy to see the location of the bonded, but basically the interface location, there is no strong tool, basically unable to open. The dismantling of the battery itself, or a little technical content, too much violence may damage the battery casing, too light and have no real effect. If we want to distinguish a dell 1691p battery have not been revised, see these seams with or without passive traces, basic can be determined.

Above the dismantling process is quite smooth, of course, the tools of the largest credit.
The configuration of a total of two sets of four green battery, looks like the AA batteries, but is not so, they just wrap up the same way, but the chemical composition and size of the inside is not the same as the next figure is closer to Figure show.

This is a group of 8-cell battery, the dell laptop battery itself, we see from Sony, the structure of the batteries of the battery itself is not a simple parallel and series, we learn the circuit, we know that the series can increase the voltage, in parallel to increase the current combination of batteries and series, the basic need batteries. Through the dismantling of the above, we probably know the batteries are shell + PCB + batteries, seem the most important part is the batteries, it is not true, the most important part of the circuit, because the use of a battery. is recorded in the circuit board. Maintenance of a battery, if you simply replace the batteries, it is of no use, because the battery itself is good or bad, always have a record. So if if there is to inquire about battery maintenance, you will find an unlock of the word, in fact, the information recorded in the circuit board lock the battery to reset, for example, the number of charge cycles, and time reset, and all good electrical core with the new battery duration. These are behind our maintenance part is to explore the content. From the above introduction, we know that lithium is the absolute protagonist, our maintenance will start from the lithium battery, lithium battery itself has many advantages, small size, relatively large capacity, it is sufficient to allow manufacturers to acceptable. Lithium itself is more active, careless and even cause an explosion. Lithium Ion batteries adding slowly over time, capacity becomes smaller, the last scrap. However, we still have many ways to avoid the accelerated aging of the lithium battery. Avoid the accelerated aging of the battery: Do not use high temperature

A 40% lithium batteries into the refrigerator refrigeration could save the decade, but an unplugged laptop, continuous use in the case of this heating, usually only to maintain 12-18. This illustrates well the lithium battery is very sensitive to temperature, if you find that laptop computers use one year later, the battery life is greatly reduced, most of the above reasons caused. But can not use the notebook will not generate heat while speaking laptop battery remove the fact, nor is it a good way, because if a sudden power failure, the computer will be as close, not only the user itself losses also accidents damage to the notebook hardware. Therefore, in the process of using a laptop to try to make the battery in a better cooling case. In general, the batteries are located in the bottom of the notebook, and therefore add a base radiator is a good choice. Prevents the battery from the accelerated aging method: Do not too many frequent and rapid charging many of my friends prefer to use the battery, whether at home or outside, and often the battery runs dry. These friends may be subject to the influence of the nickel-metal hydride battery, I feel fully charge and discharge and allow the battery is maintained at high capacity. In fact, this is the nickel-metal hydride batteries and lithium, excessive depth of discharge and fast charge will accelerate the aging of the lithium battery. This is mainly because many manufacturers are applied fast charge, two hours put the battery is full. This larger load charging the battery itself is not very good, and too much depth of discharge with a fast laptop battery charger is undoubtedly putting the two rods. Therefore, unless have to use battery or external power supply or external power supply connected. In addition to protect the battery, external power supply the notebook performance is the best processor speed faster than just using the battery, more than 40%. Save money? Playing with fire? Finally - on the laptop battery maintenance , have to talk about a problem is the battery maintenance, dismantling and principles of the lithium itself, I believe many of my friends already know, the laptop battery duration of follow bucket principle, a bucket can hold How much water is determined by the minimum side, here, too, generally speaking, the battery low-battery, a lot of time because of a batteries there is a problem, as long as the replacement of the batteries can. This processing is relatively low maintenance costs, official battery is basically replacement, the price is extremely high, so a lot of businesses saw an opportunity, at a lower price for user maintenance battery.

In fact, this is a very dangerous act, the first lithium is a very active bombings is not a two replaceable lithium batteries, if the quality is excellent but fortunately, but the merchants basic maintenance battery not the battery itself the security is too much awareness of the batteries used are relatively common, even before the old.

The general process of the battery maintenance technology, Toshiba PA3905U-1BRS laptop battery maintenance is not difficult, that is, a change of batteries solution to unlock reset under the chip. Notebook repair technicians specifically involved that step, or unlock, unlock during the storage performance of your laptop battery inside will be reset to zero even number of charge cycles. This technique, often businesses used to create new compatibility battery.
Maintenance anyway, this practice is not responsible for those repairers will not be responsible for the problem after the battery, so, we still need to take advantage of their usual maintenance than to seek medical attention more reality.

The notebook is more and more how to properly maintain your laptop battery is also more and more people are concerned about this issue will be about the content of this field.
: Notebook battery without having to run out of the power before charging
Notebook batteries are lithium batteries, lithium batteries, run out of battery again for a long time filled with do not have any role, or even harmful. Because lithium does not exist in the so-called "cache effect", only the early nickel batteries have this feature. Laptop battery life in general with the man-made damage, or natural life. Basically, the battery life are fixed 300-600 charge and discharge times, generally available 2 years.
: When the hp power adapter is connected, the battery can pull or not pull
Pull and pull depends on the actual usage: Connect the DC power at the same time do not disconnect the battery and the battery does no harm, because the battery is fully charged, will not accept any electricity into the power will be directly to the laptop power supply supply system. But when the laptop high-speed operation, the internal overheating is best to remove the battery, otherwise it is harmful.
: How correctly to the notebook battery charge
Should avoid the battery is run out of run out of recharge, because this will give the hp laptop battery a lot of pressure resulting in damage. A more feasible approach is to charge about 20-30% of power remaining. In fact the notebook lithium battery in the number of "light / charge" is limited, all used to recharge will significantly shorten the battery life. At the same time, the battery should be charged in a dry place, Also note that the heat problem, which is the enemy of the battery.
Tip:
The use of mobile phone battery with the use of laptop battery for hp pavilion dv4-5000 is not the same, a lot of people may experience in the use of mobile phone battery to determine that the laptop battery should be fully used up recharge, this idea wrong.
Laptop batteries: Long-term use how to save
The laptop battery is to put the photoelectric save or should be filled with the power to save? Put the photoelectric long-term preservation of the batteries will lose activity, and even lead to the control circuit protection self-locking and can no longer use fully charged, long-term preservation will bring security risks, the best way to save is the will power to about 40% and then stored in a cool, dry place, about 20 degrees Celsius is the ideal storage temperature. Of course, the best month to take the battery out with time, can guarantee the battery good state of preservation, but not so the battery is completely lost and damage the battery.
: Some measures of working hours to extend laptop battery
1> to reduce the brightness of the screen: you can use the fn + down / up key combination to quickly adjust brightness (specific fn + which keys need to see their own laptop).
2> use of standby, sleep and other functions: a long time without a computer, notebook standby or hibernate, saving power and extending the use of computers
Life expectancy.
> Open the cpu speedstep functionality can greatly extend the hp elitebook 8540p laptop battery working time: CPU speedstep function is the default in the bios to start when using the battery, cpu will automatically underclock to use to save energy. If not open, can boot into the BIOS, press F2 to find the Performance settings
Speedstep Enable to Enabled.
4> when using the battery, try to turn off the wireless, Bluetooth and infrared port. Removed without the use of peripherals and avoid large 3D program is enabled,
Games, to reduce unnecessary battery consumption.
