opened up my girlfriend's macbook, which had been in sleep mode for a few hours, and the screen is grey. you can see what had been up on the desktop, but it's like looking at it through a thick grey lens. everything is fuzzy, no color; it's like there's a screen over it, and then at the bottom there's what looks like a progress bar (a series of vertical dashes), that started out empty and then started moving across and filling up with white, but it stopped with three empty dashes left. any ideas on what happened and how to fix it??? please help...
EDIT: here's a pic of the screen:
edit again: when you close it/open it the sleep light goes on and off accordingly, but the apple stays lit up continuously and the screen stays backlit. you can see it around the edges. again, the screen has like a grey layer over it, you can't see the cursor, and there is zero response, with the progress bar remaining how it was in the picture. someone please help me....
