How to use the built-in battery calibration function in the notebook BIOS?

With the use of notebooks longer and longer battery life is getting shorter and shorter, many people think that the battery is bad. In fact, because the battery has been charged and discharged many times, the BIOS system of the notebook computer has judged the battery power as a fault, just like the patient was misdiagnosed by the doctor. At this time, we can make full use of the remaining power of the notebook through "battery calibration".

As for the "battery calibration" method, I first teach you two methods:
First, automatic calibration: use the battery calibration function that comes with the notebook BIOS.
Most notebooks have a battery calibration program in their BIOS. The English name is "Battery Calibration", which means "battery calibration".
The specific operations are as follows:
1. Power on, as soon as the boot screen appears, randomly press F2 to enter the BIOS menu; choose to enter the Power menu (operate the left and right keys to achieve).
2. After selecting the "Start Battery Calibration" option in the Power menu, press the Enter key.
3. After that, the screen will turn blue, and there will be an English prompt asking to charge the laptop battery. When the battery is full, the screen will prompt you to disconnect the power adapter. Then the battery starts to discharge again, and it will automatically shut down when the battery is completely exhausted.
4. After automatic shutdown, connect the power adapter to charge the battery. Be careful not to boot. After the charging is completed (the charging indicator goes out), the battery calibration process is considered complete.

Second, the manual correction method: let the notebook start to discharge naturally.
Some notebooks cannot find the option of battery calibration in the BIOS. Isn't it possible to perform battery calibration? At this time we have to perform manual operation.
1. Open the "Power Options", set the "Turn off the monitor" and "Turn off the hard disk" to the shortest time, set the "Power Supply Scheme" to "Always On", and set the system standby to "Never".
2. In the "Alarm" of "Power Options", cancel all alarm options.
3. Then close all computer applications, turn off the WIFI, unplug the power charging head, and automatically shut down after the battery is exhausted.
4. After discharging, fully charge the battery to complete a battery calibration.

If you don’t know how to set up the power management software, boot into the notebook’s BIOS and keep it on. The same effect can be achieved when the computer automatically shuts down when the battery is exhausted.

Note:
1. If the battery life of the battery is still not improved after the notebook battery is calibrated, it is mostly because your battery itself is aging.
2. If the battery life of the laptop is normal, don't make extra effort to calibrate the battery.
