tlp(8) Power Management tlp(8)

NAME

tlp - apply laptop power saving settings

SYNOPSIS

tlp command [parameters] [-- CONFIG_PARAM=value ... ]

DESCRIPTION

tlp applies power saving settings manually and controls battery care features.

COMMANDS

Profile Management

Start tlp and apply the power profile for the actual power source. Also use to apply a changed configuration or to leave manual mode.
Apply the "performance" profile. Parameters ending in _AC are used.
Apply the "balanced" profile. Parameters ending in _BAT are used.
Apply the "power-saver" profile. Parameters ending in _SAV are used. If there is no _SAV parameter available for a feature, the _BAT parameter will be used instead.
Apply profile "performance" and enter manual mode. Manual mode means that changes to the power source will be ignored until the next reboot or tlp start is invoked to resume automatic mode.
Apply profile "battery" and enter manual mode. Manual mode means that changes to the power source will be ignored until the next reboot or tlp start is invoked to resume automatic mode.

Battery Care

Change battery charge thresholds temporarily. If your hardware supports only a stop threshold, set the start value to 0. Configured charge thresholds will be restored at the next boot or by using tlp setcharge again but without the threshold arguments.
Charge battery to full capacity. This is done by applying vendor presets to the charge thresholds temporarily. Configured charge thresholds will be restored at the next boot or by using tlp setcharge without the threshold arguments.
Charge battery to the stop charge threshold once. This is done by temporarily lifting the start charge threshold. The configured start charge threshold will be restored at the next boot or by using tlp setcharge without the threshold arguments.
Force a complete or partial discharge of the battery while on AC power.
Perform a battery recalibration while on AC power: completely discharge the battery and recharge to 100%. The latter is done by temporarily applying vendor presets to the thresholds. Configured thresholds will be restored at the next boot or by using tlp setcharge.

Device Power Management

Enable autosuspend for all USB devices except those excluded by default or via configuration.
Turn off optical drive in UltraBay/MediaBay. The drive may be re-enabled by pulling the eject lever or pushing the media eject button on newer models.

Information

Print disk ids for configured drives.
Print TLP version.

Configuration

Append configuration parameters to a command. These temporarily override the system configuration during execution of that command only and are not kept afterwards. Disclaimer: this feature exists for the sole purpose of test automation during TLP's development. It is provided as is and there is no support whatsoever.

AUTHORIZATION

Almost all tlp commands require root privileges. To change the power profile without root, you may use tplctl.

BATTERY CARE

Availability of the above battery care commands and the possible charge threshold values always depend on laptop vendor or brand, Linux kernel version and TLP version. Check for actual availability, threshold ranges and battery names with tlp-stat -b. Follow the link in the SEE ALSO section for details.

For laptops with two batteries, the secondary battery must be specified as a command parameter in order to select it. In many cases the main battery will be BAT0, the secondary battery BAT1. When in doubt, the output of tlp-stat -b, which lists all batteries, can help.

POWER PROFILES

Optimizes the system for maximum performance at the cost of higher power consumption. Recommended for demanding workloads. TLP default when running on AC power.
Provides a balance between performance and power consumption. Suitable for general-purpose use. TLP default when running on battery power.
Optimizes the system for maximum battery life at the cost of reduced performance. Recommended for maximizing battery runtime.

EXAMPLES

tlp setcharge 70 90
    
tlp fullcharge BAT1
    
tlp recalibrate

FILES

/etc/tlp.conf

System-wide user configuration file, uncomment parameters here to override default settings and customization files below.

/etc/tlp.d/*.conf

System-wide drop-in customization files, overriding defaults below.

/usr/share/tlp/defaults.conf

Intrinsic default settings. DO NOT EDIT this file, instead use one of the above alternatives.

/run/tlp/run.conf

Effective settings consolidated from all above files. DO NOT CHANGE this file, it is for reference only and regenerated on every invocation of TLP.

EXIT STATUS

On success, 0 is returned, a non-zero failure code otherwise.
