system76 galago pro ubuntu linux latop
three notebooks (I wanted to find a way to control the charging threshold of the laptop battery under ubuntu linux, and finally got to the BIOS here, which should be supported by many of the latest laptops, different brands of computers may be different, If you can find the charge keyword, you can set it. The following takes the blue sky clevo notebook as an example: that is, system76 galago pro)
1. Restart the computer: F2 to enter the BIOS reboot system76 ubuntu linux system, then F2 in BIOS
2. After entering the BIOS: Advanced-> Advanced Chipset Control->Flexicharger Select Enabled
3. Set the start and end charge power: Start Charge set is 70% And Stop Charge set is 80% (default value Disable. ! Notebook battery power is lower than 95% and start charging battery power 100 % to end charging).
a. Recommended settings for new computer and new battery: start charge 70%, stop charge 80% (i: If you rarely use the battery, you can set it to a lower level: start charge 50%, stop charge 70%. ii: If you use the battery often The battery can be set higher: start charge 80%, stop charge 90%.)
b. After the laptop battery has been used for 1-2 years, increase by 10%: start charge 80%, stop charge 90%.
c. Laptop battery use 10% increase after 2-3 years: start charge 95%, stop charge 100%.
