TLP
From the project page:
- 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 the tlp package. Installing the optional dependencies may help provide additional power saving.
Enable/start tlp.service
and tlp-sleep.service
.
Radio Device Wizard (tlp-rdw)
When using the Radio Device Wizard (tlp-rdw), it is required to use NetworkManager and enabling NetworkManager-dispatcher.service
.
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.
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.). Use acpi_call-dkms if not running kernels from official repositories.
See the TLP FAQ, section "Which kernel module?", for details.
Controlling the charge thresholds using D-Bus without root privileges is possible using threshyAUR and it's example Qt user interface threshy-guiAUR.
Front end
tlpui-gitAUR is a GTK user interface for TLP written in Python. As of October 2018, the software is still in beta.
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.
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:
/etc/default/tlp
# 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
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.
If you are running TLP version prior to 0.9, run lspci
to determine the address of the GPU (such as 01:00.0), then set the value:
RUNTIME_PM_BLACKLIST="01:00.0"
If your TLP version is 1.0 or above, then set, according to the driver you are using:
RUNTIME_PM_DRIVER_BLACKLIST="nouveau nvidia"
Command line
TLP provides several command line tools. See TLP commands.
Debugging
You can display information about the currently used Mode(AC/BAT) and applied configurations:
# tlp-stat
Features intentionally excluded
- Fan control. See Fan speed control
- Backlight brightness. See Backlight
