I have a laptop which is plugged in to the power outlet 90% of the time. It is a Lenovo X1 Carbon, so the battery cannot be replaced (easily at least). I have therefore changed the battery power management to what Lenovo recommends, that is, start charging below 75% and stop at 80%. This works like a charm and the battery is rarely used at all. However, since I sometimes use it unplugged as well (and I know when in advance) I would really like to be able to force the laptop to charge to 100% instead of 80%. Is there any way that I can override the general power management in these somewhat rare cases, without manually changing power management (in /etc/default/tlp)?
