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).
For ThinkPads with more than one battery the selection works as follows:
- BAT0 - Main or internal battery
- BAT1 - Ultrabay, Slice or replaceable battery
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
/etc/tlp.conf
System-wide user configuration file, uncomment parameters

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