My retina macbook pro (15" 2012) fell off my bed and the chassis became dented on the right side. Fortunately it is working fine and the screen was closed so that was not damaged (as far as i can tell). In addition I also discovered that the screw on the bottom of the right side is missing, and the screw directly to the left of it is in place but appears not to be actually holding the bottom plate in place.
Here is the damage.
I'm have apple care 3 year warranty but I assume this would not be covered, so is there anything I can do to fix the damage (and is it even worth worrying about)? And where can I get a new screw?
