Hello, this is my fourth MacBook Pro. First one the display stopped working. Next one was an open box disaster (Best Buy). Third one had a hinge loose and apple told me to just exchange it opposed to getting it repaired. Now this one makes a clicking sound from the hinge when I first open it or when I adjust it after its sat for a while. Not only that, but when I pick it up and apply pressure on the bottom it makes a clicking sound too. This happens when its been sitting for a while and I'm not sure if its normal because its metal on metal. Anybody have similar experiences?
