My screen turns off if I'm inactive for some time, even though I disabled the setting. It happens on battery as well as on AC power.

Does anybody what I forgot or how to fix this?
I already looked at this question, but I don't want to use Caffeine.
I've watched the problem for some time now and found that it is not really reproducible. It happens very seldomly by now, but when it happens I can't find out what it is triggered by. Sometimes it's on battery and sometimes not (although I have the feeling it happens more often on battery). Also the battery loading state doesn't seem to have anything to do with it.
