Can I Set a Charging Limit on My ASUS Laptop Through BIOS or Terminal?
Asked by

Hey there! I recently picked up an ASUS TUF gaming laptop, and I'm looking to extend my battery life. I noticed the software (MyASUS) for managing settings is only compatible with Windows. Is there a way to limit the battery charge to 80% using BIOS settings or via the command line? Any help would be appreciated!

If you prefer doing it through the terminal, you can use the command: `echo 80 > /sys/class/power_supply/BAT0/charge_control_end_threshold` as root to set the limit. This will need to be reapplied after every reboot, so it’s a good idea to add it to your crontab with `@reboot`.

Just a heads-up, to access the BIOS, you usually press the 'Delete' or 'Esc' key while booting up your laptop. Check if there’s an option in there for battery settings; some laptops allow charging limits directly from BIOS.

Absolutely! You can use TLP, which is a power management tool for Linux. Just install it from your distro's package manager and check the TLP documentation for ASUS-specific settings. It has options to set charge thresholds that can limit your battery to 80% and help prolong its life.
