Screen goes white, then goes normal again after put to sleep
The screen on my macbook sometimes goes completly white. If I close the lid, and let the harddrive shut down, it goes back to normal. If I close the lid and open it again really fast so that the computer don't go into power saving mode, the screen is still blank.
Sometimes it goes white when I adjust the screen angle but mostly nothing happens when i try to reproduce the error by adjusting the screen angle or pressing along the edges of it.
It also seems to happen while doing heavy stuff like watching 1080p.
It happens maybe once an hour somedays but sometimes I can use it for 2 days without complications.
This is really wierd, i have reinstalled OSX from scratch. The computer is fully functional while display is white, I can start programs while it is white. The strangest thing is that the harddrive has to power down for the screen to get normal again. What could this be?
