              source.

       bat    Apply power saving settings for battery power source.

       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,  STOP_CHARGE  >  START_CHARGE  +  3.   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

              and recharge to 100%.

       stat   Same as tlp-stat.

       diskid Show disk ids for configuration.

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/default/tlp
              System-wide configuration file containing all power saving settings.

EXIT STATUS

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