I sent my mbp in a while ago to get a noisy fan replaced and when it came back the hinge cover was loose. Sometimes when I open the computer it makes a little clicking noise, and when I push on the middle or right side of the hinge cover it makes a creaking noise. I assume it shouldn't be able to be pulled down like that. The left side is tight and doesn't make any noises when pressed. Did they break something or is it just a couple screws they forgot to tighten? How hard would it be to take it apart and have a look see?
