Ok, so on my old white 13" MB when I pick up the computer to take it to another room with the screen open it would never move back and forth. When I would tilt it at a 45% angle it wouldn't move. Now I just purchased a new 15" MBP (sweet btw). My only issue seems to be that when I tilt the computer 45% or more the screen almost closes. Is it a weak hinge? Can that be tightened at an apple store (I am lucky and have 4 that are within about 35 to 40 minutes here in NJ)? I would open it up myself and take a look but since it's only a couple days old and I have 2 weeks with it I'd prefer to take it back to get fixed or replaced so I don't think I should open it.
