TLP is an advanced power management tool for Linux. It is a pure command line tool with automated background tasks and does not contain a GUI.
TLP is available in the AUR: tlpAUR, tlp-rdwAUR.
Features
Read the the full documentation at the project homepage.
Installation
Install the following packages plus dependencies:
- tlp (AUR) – Power saving
- tlp-rdw (AUR) – optional, Radio Device Wizard
- tp_smapi (Community) – optional ThinkPad only, tp-smapi is needed for battery charge thresholds and ThinkPad specific status output of tlp-stat
- acpi_call-git (AUR) – optional ThinkPad only, acpi_call is needed for battery charge thresholds on Sandy Bridge and newer models (X220/T420, X230/T430 et al.)
After package installation it is mandatory to enable both contained services via:
# systemctl enable tlp # systemctl enable tlp-service
Start
After successful installation, TLP starts automatically on every boot.
Configuration
The config file is located at /etc/default/tlp.
The default configuration provides optimized power saving out of the box. For a full list of options see: TLP Configuration.
To make use of the ThinkPad-specific battery options, install and configure tp_smapi and/or acpi_call (see Installation).
