Power saving made easy

by joekamprad


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 tries to keep the temperature under 45°C, to prevent hardware from overheating and also to save energy and battery life.

Nowadays Thermald is removed from the Arch repo to the AUR, so therefore to install, you can use yay or if you’ve installed a GUI installer you can also use that one. in this example we use yay. 

yay -S thermald systemd-manager

Then, start systemd-manager (will ask for password)

Most of the time you’ll get the notification that your CPU is not supported, so  you will need to add an option to the service file:

Then 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.


It will take some time before you notice the effect that Thermald has on your system, this is normal, but once the effect has taken in, you’ll never work without it again.
