I have the white Macbook (non-unibody). As I was cleaning it a few minutes ago, I broke off the cover to the up arrow key. The key and white/clear hinge thing is still attached to the underside of the key. The key works fine when I press the rubber button but the top plastic key is off. If anyone has any idea on how to get it back on, I would really appreciate it. Merry Christmas and a safe & happy New Year!
