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)

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
