- 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
- official repositories. – acpi-call is needed for battery charge thresholds and recalibration on Sandy Bridge and newer models (X220/T420, X230/T430 et al.). Use if not running kernels from
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 May 2020, the software is still in beta.AUR is a
The configuration file is located at
/etc/tlp.conf 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 on devices like 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.
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:
If your TLP version is 1.0 or above, then set, according to the driver you are using:
PCI(e) runtime power management on AC
Enabling runtime power management for PCI(e) bus devices while on AC may improve power saving on some laptops. This is enabled by default on battery, but not on AC. To enable on AC, set:
You may want to disable the autosuspend mode for certain USB devices, such as keyboards, mice or Ethernet adapters. See the TLP documentation for details.
TLP provides several command line tools. See TLP commands.
You can display information about the currently used Mode(AC/BAT) and applied configurations:
If your bluetooth headphones suddenly stop working and you see this error in
dmesg, it may be caused by TLP suspending your device. Create a file like
/etc/tlp.d/10-disable-autosuspend.conf and put this in there:
# Disable bluetooth autosuspend AUTOSUSPEND_RUNTIME_DEVID_WHITELIST="8087:0aaa"
Get the device ID for your bluetooth device from
lsusb -v. Restart TLP and the bluetooth service.
