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)

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.
