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

       start  Start tlp and apply power saving profile for the actual power source.  Also use to apply a changed
              configuration or to leave manual mode.

       bat    Apply  battery  profile and enter manual mode.  Manual mode means that changes to the power source
              will be ignored until the next reboot or tlp start is issued to resume automatic mode.

       true   Alias for bat.

       ac     Apply AC profile and enter manual mode.  Manual mode means that changes to the power  source  will
              be ignored until the next reboot or tlp start is issued to resume automatic mode.

       false  Alias for ac.

       usb    Enable autosuspend for all USB devices except those excluded by default or via configuration.

       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.

       Note: charge threshold and recalibration commands below work for specific laptop vendors and models only.
       Check the actual support status and the value ranges with tlp-stat -b. For details on  charge  thresholds
       also refer to the link at the bottom.

       setcharge [START_CHARGE_THRESH STOP_CHARGE_THRESH] [BAT0|BAT1|BATx|CMB0]
              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.

       fullcharge [BAT0|BAT1|BATx|CMB0]
              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.

       chargeonce [BAT0|BAT1] (ThinkPads only)
              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.

       discharge [BAT0|BAT1] (ThinkPads only)
              Force a complete discharge of the battery while on AC power.

       recalibrate [BAT0|BAT1] (ThinkPads only)
              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.

       diskid Show disk ids for configured drives.

       -- CONFIG_PARAM=value ...
              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.

NOTES

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

              BAT0 - Main or internal battery

              BAT1 - Secondary or replaceable battery

EXAMPLES

       Change thresholds of the main battery to 70 / 90% temporarily:

              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.
