this sort of thing a lot of contacts in my laptop 3 years ago, have only seen two cases. Instead, things like your phone number, or the quality of the battery problem in the final analysis, a large number of low-quality assembly of mobile phone batteries, and notebook computers almost never sell this battery, because no models have a large enough to warrant produce compatible battery. The reason why, after charging to 99% less than 100%, often because the battery control circuit of the records and the deviation of the state of the battery itself, the battery has not toshiba satellite A205 Adapter reached the record of the voltage control circuit, so the power control circuit has been charged, in fact, the battery has been filled, the problem can usually be resolved through the correction, but even without calibration has nothing to do, because most of the charging circuit will not be filled in automatically after a long break, and even smart auto refresh 99% of the current record is 100 %, even a fool has been non-stop design, but also because the current is very small at this time without causing damage. The current laptop batteries are basically the temperature detection circuit, when the battery temperature is too high, the control circuit will usually be forced to disconnect the battery to prevent the temperature increased further, so this situation fully to the explosion in notebook computer batteries in place no less chance of winning the lottery jackpot. No matter how scientific maintenance measures, the battery will always aging, like how the magic of cosmetics and beauty care can not prevent an old wife, at most only delay it, the only way to avoid the battery aging is to not use (so many people Select the battery to win), but this is meaningless but that laptop battery ... ... the time is always the extension with the use of aging is actually a toshiba Satellite A70 adapter Aspire aspire 5560 adaptersemi-consumables, f

battery needs to be fully charged (or put photovoltaic) preserved, whether full or shineAC adapter laptop keyboard lcd screen Acer AC Adapters, in fact, is not correct, put long-term preservation photoelectric batteries will lose their activity, and even lead to the control circuit protection self-locking and can not re-use, charged long-term preservation will bring security risks, the best preservation methods is to discharge to 40% and then save, fear of high humidity and temperature lithium battery, it should be placed in a cool dry place, but the temperature not too low, otherwise capacity will be greatly reduced, about 20 degrees Celsius is the ideal storage temperature. Seven Mistakes: batteries die, you can also change your batteries a lot of people change the batteries is such a deadly, manufacturers seem to have long been expected to do so, and many brands of laptop batteries are designed with self-locking function, once batteries from the control circuit, the circuit to enter the self-locking state, only the use of specific tools to unlock, before the control circuit will not work, that is the same scrap batteries, laptop batteries batteries are not free to change the batteries, If you do not have to change batteries, please Toshiba PA3165U-1ACA adapter Dell Inspiron E1505 Adapterremember to find the battery maintenance company dedicated to wield the sword, their little trouble for waste, the kind of effort also failed after the frustration and depression is the most miserable. Error Eight: 99% charge less than 100% since been and continue to charge laptop battery will explode almost no chance of explosion, at most, a result of shell melting heat issue, but few can cause fire, was released a few incidents, in fact When the production process as bad, cause a short circuit in the use of a result, even if most of this will be short-circuit protection circuit disconnects the battery circuit Buzhi Yu greater damage, unless it is in the batteries before the protection circuit Short (prior to the time COMPAQ laptop battery explosion was so caused should be),

consumption, while only one desktop CPU frequency display. 3, the LCD screen: beautiful eyes In the purchase, the LCD screen need to note a few places, one dead pixel problem, the second is reaction time, third-grade LCD screen itself. Dead pixel problem is often said that the LCD screen are bright or dark spots. To avoid dead pixels necessary to ensure that each TFT tubes and liquid crystal device is not bad, which is very high on the process requirements. So the state is less than seven the following for qualified products, to test whether there are dead pixels as long as the LCD screen displays a monochrome image, carefully observe whether the particular highlight on it. Furthermore is the reaction time. System response time is the input device receiving the instruction, reflecting the time to display, that is, examine whether there is smear phenomenon.

The most simple test is to open a particularly long way to the text, hold down the button to scroll down to observe the screen to know. Response time is as short as possible.

First, the laptop brands: Generally can be divided into the following categories: 1) The international brand. Mainly the United States Dell laptop keyboardhp laptop keyboardtoshiba laptop keyboardand Japan, the brands, including IBM, Toshiba (TOSHIBA), DELL, Compaq (COMPAQ), Hewlett-Packard (HP) and so on. Its brand more outstanding product quality, market share is very high, of course, the most expensive price. 2) Taiwan brand. Include Acer (Acer), Asustek (ASUS), Twinhead, Lianbao and so on. Such notebook technology is mature, relatively cheap, people buy very much. 3) domestic brands. There are Lenovo, Founder, purple and so on. As cheap, easy maintenance, more and more user favorite. Second, discuss the main components: 1, the board: the cornerstone of a strong The integration of laptop computers is very high. Some major functions are concentrated on the motherboard, the motherboard determines the performance of a direct machine

performance. Intel's chip set is the best performance and quality, the price is the most expensive; In addition, the most common is the SIS and ALI chipsets, and low-priced machines generally use two chips, stability is very good, but in performance compared with Intel, there is a considerable gap. 2, CPU: healthy heart If the design from the strict point of view, used in the notebook computer CPU to be "dedicated processor notebook computer", commonly known as "Mo  bileCPU". If the notebook uses desktop CPU, will increase the burden on the cooling system and machine weight. So here I do not recommend buying laptops with desktop processors. So, when we in the purchase be sure to ask whether to adopt a laptop-specific processor. Here to teach you a way to differentiate: the WINDOWSXP system, in the "My Computer" right click select "Properties" to connect a system status bar, status bar has

More important issue may be the books of the data security, a sudden stop working for the automatic protection of the computer is a terrible thing, especially a lot of friends without the battery. Sometimes a reboot the computer somehow and relevant. For the first wife of the power supply, the manufacturers know what kind of access is a load, so you can easily calculate the nominal power supply voltage and nominal current, the nominal voltage power supply should meet the following two conditions, first when the nominal maximum current output voltage minus the power supply itself should be larger than the load required voltage drop of 95%, the second is the smallest when the current output voltage minus the power supply itself, the design should be less than the required load voltage drop of 105 %. However, if the adapter using a non-original equipment, such as general purpose transformers and the like, the problem can not be seriously considered, this is from the electrical parameters of the user can only think of ways to be compatible as far as possible, but the resistance is different for each adapter , the nominal voltage of the allowable error may be different, under the nominal current output voltage range of the definition may be different, and even output ripple factor is not small enough not necessarily, if not carefully measured the output power with the relationship between the output voltage, in principle, there is a certain risk, but this risk is small, because if you choose to supply enough current nominal resistance does not appear the problem is too large, the ripple coefficient can also be stable within books pressure to reduce, so I said, first wife of the power

Here to talk about why the first wife of the power supply is usually better than non-first wife. I want to say first wife's power theory is relatively better, in fact, may not feel different. Allowable load is usually a safe range of input voltage, such as the nominal value plus or minus 5%, one example is that many 2.5-inch hard drive 5v input requirement is plus or minus 5%. Notebook, too, if the input voltage is too large or too small will result in protection circuit action, in order to stop work.
