1. Don’t rush to charge your laptop after you buy it.
First of all, the original battery of the new battery should be used up and then charged. The specific method is to use the battery alone without AC external power supply. Complete the discharge operation according to the following steps (indicated by wIndows xP):
Click on the Control Panel – Performance and Maintenance – Power Control – An alarm will be cancelled. When the power shortage alarm is cancelled, when the critical power shortage alarm is reached (1 – 2% alarm is set), it will be considered as fully discharged and shut down (be careful not to use the off The power is off by itself, so there is no difference with power off, and it will cause some damage to the notebook.) After the discharge is completed, charge it to full charge (preferably in the off state, and do not select the power supply during charging, and when When the charge indicator is off, it will continue to charge for a period of time. In many cases, the battery will only have 80-97% of power, and it will return the power reminder alarm to the initial warning state. Pay attention to the completion of charging, wait about 30 minutes until the battery is basically cooled before use.
2. The battery life is not determined by the total usage time, but by the actual number of charge and discharge times.
The second method of battery maintenance for notebook computers is that if the battery is always attached to the computer without removing it, after removing the AC power source, since the environment where the battery is located cannot be absolutely insulated and the control circuit is integrated in the battery, even The battery will gradually discharge when the computer is turned off. When the AC power is connected again, the battery will begin to charge (most batteries are designed to start charging under 95%, different battery designs are different), so the battery will be charged repeatedly whenever the power is turned on or off. And discharge. This practice is very damaging to nickel-hydrogen batteries that have a strong electrical memory effect. Although the ionization effect of buried ions is relatively small, long-term incomplete charging and discharging will also reduce the battery to some extent. Life; In addition, the heat generated by the computer will also affect the battery life.
Therefore, under the condition that the power supply of the computer environment is stable, it
is recommended that everyone remove the battery and use the power adapter alone to supply power. The purpose of this is to simply prevent the battery from being frequently charged under incomplete discharge.
