You have been subscribed to a public bug:
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.
