In this way, at least two cycles back and forth. Second, the unstable factors of the battery in use and charging will cause the capacity of the battery to decrease, but this decrease is not caused by aging, so proper calibration can restore this part of the lost capacity of. Therefore, it is very necessary to perform battery calibration regularly, such as once a month in January.

Method three: Use the battery refresh program to restore the battery discharge time: Most branded laptops have a battery refresh program, which can be used to repair the battery. There is a software called BatteryMon. There are many versions. It is a small software specifically for notebook battery monitoring. It can display the discharge curve and run automatically after installation. For laptops, the battery is charged and discharged improperly, which leads to shorter and shorter discharge times, with less than 5 minutes left. It is very inconvenient to carry the laptop to work. Which methods can restore the battery? What about the discharge time? Battery repair In response to the above situation, we can use the battery refresh program introduced by ibm to refresh the battery to restore the discharge time. The specific methods are as follows. (1) Use alternating current to supply power to the notebook computer, and download the refresh program of the supplied notebook computer battery. (2) Restart the computer, press the f8 key to enter the boot menu, and select the safe dos mode.
