Hey there! I recently got a new ASUS TUF gaming laptop, but I've found out that the software MyASUS for setting battery limits only works on Windows. I'm looking for a way to set a battery charging cap at 80% through either the BIOS or the terminal so that I can extend my battery life. Any suggestions?

Another way is to execute a command in the terminal. You can use `echo 80 > /sys/class/power_supply/BAT0/charge_control_end_threshold` as root. Just a heads up, this command won't persist after a reboot, so you'll need to add it to your crontab as an `@reboot` job to make it stick.
If you want to go the BIOS route, you can usually enter BIOS by pressing the delete or escape key right when you start your laptop. Look for battery settings there, but keep in mind that not all BIOS options might allow you to set a battery threshold.
Once you have TLP set up, you'll need to edit the `tlp.conf` file to specify your charge thresholds for BAT0 or BAT1. You'll find options for setting when charging starts and stops. If you need more help with that, just ask!
You can set that up using TLP! Most Linux distros have it available in their repositories. Once you install it, check out the TLP documentation related to battery settings specific for Asus laptops. It should guide you through setting the charge limit you want.
