Public bug reported: When I'm working without the power cable connected (mostly), I noticed that after some while - still can't identify a pattern - the screen starts to flicker and then goes black/turn off. Closing the lid and reopening after few secs restores the screen (sure at that point I have to log in again).
As far as I've seen, if a second screen is connected, this is not happening. But at that point I have the power cable in. So this might explain why.
