Enable Automatic Suspension in Ubuntu Linux Easily
Automatic suspension is a power-saving mode that puts your computer to sleep after a set period of inactivity to save battery and electricity. Ubuntu 22.04 LTS and newer versions let you set different idle timers for when your laptop runs on battery power versus a wall charger.

Go to Settings , then Power. Under Automatic Suspend, choose On Battery Power or Plugged In, turn the switch on, and select a delay time for your system to suspend when idle.
