I have a brand new 15" i7 Macbook Pro that I bought from the Apple store over 14 days ago. I opened it up to put in an SSD drive and optibay. Now, this was my first time opening up a unibody, but I've opened up many notebook computers and older style Macbook Pros before, so I'm not a newbie. However, putting things back together I ran into a problem. One of the screws that secures the metal plate on the bottom of the machine will not catch in it's hole, and therefore does not stay in. I swear I did nothing to strip this screw or the hole it goes into. When I screw the screw into the hole with the case off, it smoothly sets and seems to be fine. However, when the metal plate is put on and the screw is put threw it, it's like the screw is not long enough to reach the threaded part of the hole Yes, I'm positive it's the right screw. The hole I'm talking about is along the back side of the computer, towards the hinges, and is the only one of the 4 screws that is the shorter style screw (vs the long ones that occupy the other three holes). I'm at a loss for what to do. I'm thinking about putting all the stock stuff in place and taking it into the apple store for help at this point. Does anyone else have any better advice?
