The following shows how you can optimize your computer using Powertop to generate runing recommendations and apply those optimizations at boot using an rc-local service.
sudo pacman -S powertop
Run powertop report (on battery power)
sudo powertop -r
After a few seconds, a file called powertop.html is created.
Open the powertop.html file in your browser and inspect the Tuning tab for tuning recommendations.
Configure rc-local service
Create rc.local file in
/etcdirectory with the following content
#!/bin/sh -e echo "Hello World" # Insert powertop optimization scripts here. exit 0
Create rc-local.service file in
/etc/systemd/systemdirectory with the following content
