- TLP brings you the benefits of advanced power management for Linux without the need to understand every technical detail. TLP comes with a default configuration already optimized for battery life, so you may just install and forget it. Nevertheless TLP is highly customizable to fulfill your specific requirements.
Contents
Installation
Install tlp from the official repositories - pay attention to its optional dependencies that may help provide additional power saving.
To complete TLP's install, you must enable the systemd services tlp.service and tlp-sleep.service. You should also mask the systemd service systemd-rfkill.service to avoid conflicts and assure proper operation of TLP's radio device switching options.
ThinkPads only
For advanced battery functions, i.e. charge thresholds and recalibration, install the following package(s):
- tp_smapi – tp-smapi is needed for battery charge thresholds, recalibration and specific status output of tlp-stat
- acpi_call – acpi-call is needed for battery charge thresholds and recalibration on Sandy Bridge and newer models (X220/T420, X230/T430 et al.)
See the TLP FAQ, section "Which kernel module?", for details.
Start
After installation TLP will be automatically activated upon system start. To start it immediately without reboot or to apply changed settings, use:
# tlp start
Configuration
The configuration file is located at /etc/default/tlp and provides a "largely" optimized power saving by default. For a full explanation of options see: TLP configuration.
Btrfs
To avoid filesystem corruption on btrfs formatted partitions, set:
SATA_LINKPWR_ON_BAT=max_performance

Bumblebee with NVIDIA driver
If you're running Bumblebee with NVIDIA driver, you need to disable power management for the GPU in TLP in order to make Bumblebee control the power of the GPU.
Run lspci to determine the address of the GPU (such as 01:00.0), then set the value:
RUNTIME_PM_BLACKLIST="01:00.0"
Radio Device Wizard
The Radio Device Wizard allows a more sophisticated management of radio devices depending on network connect/disconnect events. It requires NetworkManager, tlp-rdw and enabling NetworkManager-dispatcher.service.
See TLP configuration for details.
Command line
TLP provides several command line tools. See TLP commands.
Debugging
You can display informations about the currently used Mode(AC/BAT) and applied configurations:
# tlp-stat
