I have an old Aluminum 13" MacBook (equivalent to the current 13" MacBook Pro). Recently, someone bumped into the monitor and knocked the laptop back a little. I found that the right side of the black piece of plastic connecting the monitor to the MacBook will move out a few millimeters when I wiggle it. The left side is stable, and the laptop and monitor still works. Does anyone know if this will cause any other problems, and how would I go about fixing this (and how much would it cost)? Thanks for any help.
