NAME
tlp - apply laptop power saving settings

SYNOPSIS
tlp command [parameters] [-- <config> ... ]

DESCRIPTION
Apply power saving settings manually and control ThinkPad battery features.

COMMANDS

start
    Initialize tlp and apply power saving settings according to the actual power source. Also use to apply a changed configuration.

bat Apply power saving settings for battery power source.

true
    Same as bat.

ac  Apply power saving settings for AC power source.

false
    Same as ac.

usb Enable autosuspend for all USB devices, except blacklisted ones.

bayoff
    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.

setcharge [START_CHARGE STOP_CHARGE] [BAT0|BAT1] (ThinkPads only)
    Set charge thresholds of main (BAT0) or auxiliary (BAT1) battery temporarily. Values must be between 1 and 100, START_CHARGE must not exceed STOP_CHARGE - 4. Configured thresholds are restored upon next system boot-up. When called without arguments, configured thresholds are set.

fullcharge [BAT0|BAT1] (ThinkPads only)
    Set charge thresholds of main (BAT0) or auxiliary (BAT1) battery to factory presets (96/100) temporarily (causing a full charge). Configured thresholds are restored upon next system boot-up.

chargeonce [BAT0|BAT1] (ThinkPads only)
    Charge main (BAT0) or auxiliary (BAT1) battery to the stop charge threshold once (bypassing start threshold). Configured thresholds are restored upon next system boot-up.

discharge [BAT0|BAT1] (ThinkPads only)
    Force complete discharge of main (BAT0) or auxiliary (BAT1) battery.

recalibrate [BAT0|BAT1] (ThinkPads only)
    Battery recalibration: completely discharge main (BAT0) or auxiliary (BAT1) battery and recharge to 100%.

diskid
    Show disk ids for configuration.

-- PARAM=value ...
    Add parameters to temporarily overwrite the system configuration (for this program invocation only).

NOTES
For ThinkPads with more than one battery the selection works as follows:

    BAT0 - Main or internal battery

    BAT1 - Ultrabay, Slice or replaceable battery

EXAMPLES
Apply thresholds of 70 / 90% to the main battery:

    tlp setcharge 70 90 BAT0

Charge the auxiliary battery to full capacity:

    tlp fullcharge BAT1

Recalibrate the main battery:

    tlp recalibrate BAT0

FILES
/etc/tlp.conf
