Generally speaking, if you can select the charging method during power-on charging, do not select the Express charge mode to avoid the battery being “full†too early. When the battery is low, it is forbidden to use the highest performance of the CPU to reduce the competition for power. If the CPU used in the notebook is supported by SpeedStep technology, it is easy to adjust the performance. The icon of the SpeedStep program is a blue flag. Right click on it to display the performance adjustment options. Under Windows XP, the SpeedStep program may have problems. At this time, you can only modify the BIOS parameters of your computer, or use some brand-specific adjustment programs.
The parts of the protection circuit of the laptop battery are usually voltage regulating blocks, control chips, insurance, temperature probes, and the like. The temperature protector is usually disposable and has a fuse inside (some are 130 ° C blown) to monitor the operation of the surge block. If the charging and discharging process is abnormal, a current will immediately blow through the temperature protector, and the internal circuit of the battery is now open and cannot be recovered. If you want to repair only the temperature protector, but this type of temperature protector is hard to find on the market. Therefore, the maintenance cost of the battery is high.
The battery will definitely wear out after use, so users will find that the battery is becoming less and less "used." If you find that the battery is very worn out, you can use a dedicated repair program to restore battery performance, such as THINK and other notebooks with a power management program. If there is no repair procedure, it can be recovered by repeated charging and discharging 2 to 3 times. Some people think that after the battery is fully charged, the external power supply is unplugged, and then the battery is completely discharged after the battery is used up. This is actually not the case. After the battery warning occurs, you must enter the BIOS state before shutting down, do not operate, and then completely discharge when the computer is turned off. In addition, do not start charging when you start charging, it is best to turn it on again after a few minutes. If the charger has a display light, the charging indicator will flash at the beginning, and then turn it on when it is not flashing.
