Save battery on ThinkPad

You can set how many percent the battery is charged to on the ThinkPad and when the battery should start charging. A full charge to 100% is harmful.






I have installed Ubuntu 22.04.2 on the Lenovo ThinkPad without operating system. Windows comes with a utility to set the battery charge. Here's what I did on mine:

Install TLP:
 sudo add-apt-repository ppa:linrunner/tlp
 sudo apt update
 sudo apt install tlp

Check what package needed for battery:
 sudo tlp-stat -b

If acpi_call is recommended
 sudo apt install acpi-call-dkms

If smapi is recommended
 sudo apt install tp-smapi-dkms

Open config file of TLP
 sudo gedit /etc/tlp.conf

Find the lines regarding battery settings,
remove the leading # for comment and maybe insert the value you want
 START_CHARGE_THRESH_BAT0=75
 STOP_CHARGE_THRESH_BAT0=80

Restart tlp
 sudo tlp start
Check the config status
 sudo tlp-stat -b

Important, picture up, picture down, position 1 and end are executed as single keys. Why do other notebook manufacturers save on the keyboard of all things?
