I got this laptop for Christmas, so it's not even a month old. I have seen a few threads on this issue, but I didn't really see a fix. If I have the Macbook on my lap and move the left side to the left so it's off center on my lap and press down on the left side of the top part, it creaks. If I press on the bottom towards the left/middle, it creaks.I just noticed this in the past few days. I can see if I can tighten the screws or should I take in the the Genius bar? I do plan on getting Apple Care, but I don't need it right now. Other then that, it seems solid everywhere else. Isn't the processor on the left side? I mean more components on the left vs. the right? It's definitely warmer on the left side.
