Recently I've noticed that my top lid on my Mid-2010 MBP has become out of alignment with the bottom one, the back plastic piece is sticking out on one side as well. I tried nudging it back into place but it doesn't seem to work. It's 4 months old and has no scratches, dents, or any other problems, and I keep my screen in perfect condition. Should I take this to an Apple Store? Or is it something I shouldn't worry about.
