Power Saving Made Easy

TLP

for notebooks: https://wiki.archlinux.org/index.php/TLP

Install TLP from the official repositories - pay attention to its optional dependencies that may help provide additional power saving:

  • acpi_call: ThinkPad battery functions, Sandy Bridge and newer
  • bash-completion: Bash completion
  • ethtool: Disable Wake On Lan
  • lsb-release: Display LSB release version in tlp-stat
  • smartmontools: Display S.M.A.R.T. data in tlp-stat
  • tp_smapi: ThinkPad battery functions
  • x86_energy_perf_policy: Set energy versus performance policy on x86 processors

sudo pacman -S tlp

To complete TLP's install, you **must enable** the systemd services **tlp.service** and **tlp-sleep.service**

sudo systemctl enable tlp.service tlp-sleep.service

You should also mask the systemd service **systemd-rfkill.service** and socket **systemd-rfkill.socket** to avoid conflicts and assure proper operation of TLP's radio device switching options.

sudo systemctl mask systemd-rfkill.service systemd-rfkill.socket

 

 

Thermald

https://01.org/linux-thermal-daemon

It try to keep tempertature under 45°C and will save hardware from overheating and so save energy/battery

sudo pacman -S thermald systemd-manager

start systemd-manager (will ask for password)

As mostly it will not start thermald caused by your CPU is not in the database.. you will need to add an option to the service file:
--ignore-cpuid-check


Easy choose thermald and the tab "File" on its config (right sided)
Add --ignore-cpuid-check to the ExecStart= line and save the file (bottom button 😉 )

now enable the service with the top slider, close the program.

reboot...

It will take some time to get fully working but is doing a good job!
