From the project page:
- TLP is a feature-rich command line utility for Linux, saving laptop battery power without the need to delve deeper into technical details.
- TLP’s default settings are already optimized for battery life and implement Powertop’s recommendations out of the box. So you may just install and forget it.
- Nevertheless TLP is highly customizable to fulfil 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 settings for details.
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
- 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 do I need for my ThinkPad?", for details.
Controlling the charge thresholds using D-Bus without root privileges is possible usingAUR and its example Qt user interface AUR.
- GTK user interface for TLP written in Python. AUR is a
- AUR is a different GTK interface that works with addional drivers like AMD and NVIDIA.
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 settings.
When starting TLP with the default configuration, some USB devices such as audio DACs will be powered down when running on battery due to TLP's autosuspend feature. Some devices such as keyboards and scanners are blacklisted from autosuspend by default.
You may simply want to disable USB autosuspend entirely with the following setting:
# Do not suspend USB devices USB_AUTOSUSPEND=0
Or blacklist specific devices from being auto-suspended. See the TLP documentation on USB devices for details.
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
Bumblebee with NVIDIA driver
If you are 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.
Depending on the driver(s) that you are using, blacklist one or more of them, preventing TLP from managing their power state:
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:
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 from dmesg, it may be caused by TLP suspending your device. Add device ID to
# Disable bluetooth autosuspend USB_BLACKLIST="8087:0aaa"
Get the device ID for your bluetooth device from
lsusb -v. Restart TLP and the bluetooth service.
