I've recently bought this laptop: NP305V5A-S03IT, with the new AMD A8 APU and a dedicated video card in crossfire.
Anyway, from time to time (I think once or twice in an hour), the display turns black for a fraction of second (couldn't say if the backlight or the entire screen, it's fast but I think the first).
I tried to connect an external screen (a TV to be exact), and for what I've seen it doesn't happen with that (but the screen does); so it might be a problem of the screen itself, I think.
Somebody has a better idea?
(I'm not sure about the title, maybe there is a better word for this)
