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

yay -S thermald systemd-manager

thermald is removed from Arch-Linux repo, only at AUR for now….

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!
