Lid will not shut completely. Hinge too tight?
I have a 2012 MacBook Air, obviously out of warrantee, that suddenly will not close all the way. It was a problem on one side only at first, but it’s getting worse with a half inch between the lid and the body of the machine. I opened it up and removed the screen. I’ve found that one hinge is moveable with my fingers alone. The other is so tight it needs a wrench to move. I can’t tell which is “normal” or if either is the problem. I can say that when the machine is assembled the tighter hinge will not move past a certain point when closing and that may be the reason the screen bounces back open. My only idea is to wd40 it a bit to see if it loosens up, but I’m loathe to do such a thing without checking here first. I wouldn’t want a screen so loose it can’t stay open.
