Hi Guys, Over the past few days, I've noticed that my MBP won't close. Early weekend I would be able to close it, but if I came back in a couple hours or so the lid would be slightly opened. Now today I can't close it at all. Should I bring it in? and if so is this a simple repair that can be done in store? Also occasionally I've been hearing some kind of a humming noise coming from the right speaker by the power button, sometimes its really loud, it was happening a lot over the weekend, but hasn't happened today yet. Suggestions?
