That particular model, like Kris says, has a tiny cable connecting both trackpad and keyboard to the logic board. There is a possibility that this connection is either loose or breaking. I would not recommend anybody to try re-seating it, as it is very fragile and can easily break. I know it for a fact, since it happened to me while upgrading the HD and optical drives. That's one of the instances that calls for professional help --unless of course one knows soldering and REALLY handy stuff.
