My new macbook pro 15" makes a popping or cracking sound on the right side of the hinge and it's getting worse. It use to pop once or maybe twice some of the time when I opened it, now it's more like 6 or 7 times. I ran a search but I'm not sure if the sound mine is making is the same as those of the other people. Also, when I look down at my hinge when the computer is placed vertically, the black plastic piece is off center to the right. Is this a problem that could continue to get worse? Is this somewhat normal? I'm really particular, and this doesn't bother me that badly, but I would like my MBP to be perfect, at least as long as it can be.
