Just cleaned up a A1286 mbp mid2010 from a spilled cup of tea. The machine works except the keyboard+power. have tested two different keyboards, same issue, i figure it must be the logic board. So i cleaned it up real nice, but found a chip near the keyboard connection socket which looked like it had som residue covering it. After i had removed the residue, the chip looked like it was missing a pin. On this pics from ifixit the chip has all pins, on my LB ones is missing. i have marked which pin is missing. see pic Does anybody know what the chip do or controlls? Is there somewhere i can get a datasheet of the LBs architecture?
