Hello! Once again I need you guys here at macrumors! Last night, when I closed the lid of my umbp, I heard this crackling noise. The results can be seen in the pictures. It's not as bad as it looks. Its the alumin(i)um cap that's come loose from the display at the corner. Each time as I close the lid , I get this gap as you can see in the pictures. But when open, the cap just fit's snugly around the screen as it is used to. What happened here? Are the displays glued to the aluminium cap or something? Anyone else had this problem? And most of all: will they be able to fix this at the applestore or do I need a whole new screen? Thanks!
