Powertop & Tuned Subject description: to minimise a computer's electrical power consumption & system-tuning daemon
Powertop PowerTOP is a software utility designed to measure, explain and minimise a computer's electrical power consumption. It was released by Intel in 2007 under the GPLv2 license. It works for Intel, AMD, ARM and UltraSPARC processors.
To configure PowerTOP on your system, simply calibrate it, enable it, and start it:
powertop --calibrate: This will take a while and do things such as change the brightness of your screen.
systemctl enable powertop: This will enable PowerTOP the next time you reboot.
systemctl start powertop: This will start PowerTOP in auto-tune mode.

Tuned is a dynamic adaptive system-tuning daemon that tunes system settings dynamically depending on usage (also from the man pages). To configure tuned on your system, simply enable it, start it, and pick a performance profile:
systemctl enable tuned
systemctl start tuned
tuned-admin list (shows all the available profiles)
man tuned-profiles (if you want to learn more about each profile)
tuned-admin profile desktop (changes your system’s tuning profile to desktop)
