My new 13.3" Unibody MacBook Pro has been great up until now. I've had it since September and it's worked without a charm. For some reason, as I went to close the hinge (slowly) today, it made an extremely sharp cracking sound, as if the screen had broken off. I had mini-heart attack on the inside, thinking that the screen of my MacBook Pro had just broken. I quickly opened the screen to see that nothing was damaged. I went to close it again and I went past the point that the cracking noise happened at (it sounds like it gets caught). As I kept closing it, the cracking noise happened about 3 more times. No noises come from it as I open the MacBook Pro, but when I slowly close it, it cracks (really loudly). I've been closing the lid really quickly now, and no cracking sounds occur when I do that. Do you think it's a loose screw or something like that? Should I take it into an Apple Store to see if they can fix it? This laptop is like my baby. Edit: I somewhat temporarily alleviated the issue by pushing a piece of paper through the hinge and out the back of the laptop an pulling it back and forth. The hinge worked well for about 5 times, then started cracking again. Edit: Now that I think about it, it might be caused because it's been on for about 11 hours. I've never worked it this hard before. I'll try again after I go to sleep, and see if the problem has gone away. Edit: Okay, the problem is a little better now. There are still tension points (there are less though), but they don't crack very often as I go past them.
