Well, I have a 15" MBP intel core duo with a 1.83GHz processor (one of the very first models). I need to replace my keyboard because a few of the keys don't work but I'm having trouble finding which keyboard is compatible with my specific machine. Does anyone know how I can find out which keyboard is for my specific machine? I just want to make sure I am order the correct piece first because I have found plenty of different keyboards on numerous sites that all say different things. Ex: part number xxx-xxxx or ribbon number: XXXXXXXXXXXX The ribbon number on my keyboard is AEPW1PLU016 but I can't find the part number anywhere. thanks for your help in advance.
