This is actually a rather common fault with this line of MBPs. As the power button still works i believe (don't know for sure) that the USB controller on the topcase fails. Keyboard and trackpad are connected via USB internally. Open up system profiler and you'll shure won't find them listed anymore. Have a look at [http://www.ifixit.com/Answers/View/25532/Internal+keyboard+%26+trackpad+quit+working.+Please+help+diagnose!#answer25613|this] discussion.
