Ive decided tobrepair my old 2009 mbp, which had this problem after spilling water on it. It boot fine and the fan runs normal and it operates normally when the internal keyboard is disconnected. As soon as i connect it, it stars running slow ad the fan goes to 6000 rpm. Everthing looks to be ok internally... I reset the pram and smc but it made no difference. Ayone know a solution to this or what coul be causing it? I coulnt figure out how to remove the keyboard.
