My Dell XPS 13 (Windows) will kill it's battery if you look at it funny... Or don't look at it at all.
One time, I fully shut down the laptop and put it in my carry-on.
When I took it out after my flight, my bag was suspiciously warm and the battery was fully dead. Power management on Linux might be a joke but Dell is certainly the Carlos Mencía of the comedy club. At least I know my enemy now though. I unplug the battery to turn it 'off'.
