- 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.
Install the package. Installing the optional dependencies may help provide additional power saving.
Radio Device Wizard (tlp-rdw)
One should also mask the service
systemd-rfkill.service and socket
systemd-rfkill.socket to avoid conflicts and assure proper operation of TLP's radio device switching options.
See TLP configuration for details.
For advanced battery functions, i.e. charge thresholds and recalibration, install the following package(s):
- – tp-smapi is needed for battery charge thresholds, recalibration and specific status output of tlp-stat
- – 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.
Controlling the charge thresholds using D-Bus without root privileges is possible usingAUR and it's example Qt user interface AUR.
GTK user interface for TLP written in Python. As of October 2018, the software is still in beta.AUR is a
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.
Force battery (BAT) configuration
When no power supply can be detected, the setting for AC will be used (e.g. on desktops and embedded hardware).
You may want to force the battery (BAT) settings when using TLP on these devices to enable more power saving:
# Operation mode when no power supply can be detected: AC, BAT. TLP_DEFAULT_MODE=BAT # Operation mode select: 0=depend on power source, 1=always use TLP_DEFAULT_MODE TLP_PERSISTENT_DEFAULT=1
To avoid filesystem corruption on btrfs formatted partitions, set:
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.
lspci to determine the address of the GPU (such as 01:00.0), then set the value:
TLP provides several command line tools. See TLP commands.
