It's not much tinkering at all. Once you've installed powertop (probably just "dnf install powertop" or "apt install powertop", or whatever your favorite flavour is), you can just run "sudo powertop --auto-tune"[0]. If you do like to tinker, you could maybe write your own init script to run that on boot, but your distro probably included one already.
