I received a new 15" MBP Core i7 about a week and a half ago and it was in perfect condition. Today, I noticed when I open / close the screen there is a point that the hinge makes a "pop" sound... In addition, the hinge is weaker than it once was. The first day that I got it I held it at a 90 degree angle and the screen held itself perfectly, now it falls like down has been shown in previous models. Has anyone else experienced this with the 2010 models and is going to the Apple Store to have them check out the "pop" the best solution?
