Correct charging and discharging to prolong the laptop battery life

In general, when you start charging, if we can select the charge, do not select the fast charge mode (Express charge mode), to avoid premature battery "full". Low battery prohibit the use of the highest CPU performance, in order to reduce the power of the competition. If the laptop CPU support SpeedStep technology, you can easily adjust the performance. SpeedStep program icon is a blue flag, right-click on it to performance tuning options. Windows XP system, SpeedStep program may be a problem, this time can only modify the computer's BIOS parameters, or the use of brand-specific adjustment program.

Laptop battery protection circuit parts are usually the voltage regulator block, control chip, insurance, and temperature probes. Temperature protection device is usually a one-time internal fuse (some 130 ° C fuse), used to monitor the voltage regulator block work. If the charge-discharge process exceptions, immediately there is a current through the temperature protection fuse is blown, the internal circuit of the battery as a cutoff state, and can not restore. If you want to repair only the replacement of temperature protection, but these shall only be such as temperature protection is difficult to find in the market. Therefore, the cost of maintenance of the battery is higher.

Battery after use will certainly be a loss, so users will find the battery less and less by. If you find that the battery depletion can fix with a dedicated restore the battery performance, such as THINK notebook with the power management program. If there is no fix available 2 or 3 times repeated charge and discharge to recover. Some people think that after the battery is fully charged, unplug the external power supply, and then wait until the shutdown has been fully discharged battery runs out. In fact not the case. After the battery warning appears, enter the BIOS state before shutting down operation, wait until the computer shuts down only truly fully discharged. Not start charging, a charging boot, preferably every few minutes, and then boot, if the charger indicator lights, just start charging indicator will flash the time not flash and then boot.
