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
              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.

       /etc/default/tlp
              Obsolete system-wide configuration file.  DO  NOT  USE  this  file,  it  is  evaluated  only  when
              /etc/tlp.conf is non-existent.

EXIT STATUS

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