T520 Screens (internal & docked external) blackouts

I have a friend who says her external monitors (she has 2 connected to her dock) have been randomly flickering/going black momentarily (and always simultaneous/syncronized with each other) for the past 3 weeks or so. 

The other day her internal screen went black for about 15 minutes, and by restarting several times, she said it eventually came back.

She said the battery was low when her internal screen went down, but I don't think that would be a cause (as it happens when she is docked and charging)

I checked the graphics drivers, everything was up to date, but the "Monitor" driver needed an update. Again I don't think that would solve the issue as it is also doing this on her dock.

Any thought on what could cause this?
