I took apart my macbook to fix the IR cable and since the keyboard was out i decided to clean it. When i put it back, turned on the computer... everytime i hitted enter it repeated as if it was stuck. then i noticed most keys from the right side didnt work. after a few minutes, no key worked at all but the power key, eject.. and the trackpad and its button. I think i made a mess when i cleaned it or something, and i'll just have to order a new one from ifixit.com. But i wonder why the trackpad, eject and power key do work. Maybe there's something i can do? any tips on how to debug what could be malfunctioning?
