I'm using my second late 2008 MBP. I got the first one replaced at a local Apple Store because of graphics issues. After having this one for a few weeks, I've noticed that most of the time when I move the screen down or up, I hear a slight yet obvious creaking/cracking noise. I'm not sure what the cause of this is, but I think it is a misalignment of the screen hinge. Here are some pics: Left side of hinge (not touching the aluminum unibody at all): Right side of hinge (all of it is in contact with the aluminum): I've already taken it to the Genius Bar at the local Apple Store, and the guy I talked to (the same guy who gave me the replacement last time) told me that they could not replace it, but could realign the screen for me. I ended up telling the guy that I might come back later to get it repaired, but wasn't sure. What I am wondering is if this problem warrants a replacement or not. I've had bad experiences with repairs before and would like to just get a replacement instead of hoping that the technician knows what he/she is doing. Any advice/of you had the same problem with your MBP?
