Don't know where to start here. Board was very lightly water damaged. Has a bit of corrosion on u5800 and keyboard connector. cleaned both off. Board has green/orarange light and fan spins but no chime and does not boot.
CPU getting warm or staying cold? Probably corrosion somewhere. The usual suspects are U1900 and traces to its crystal, crap under SMC, possible U6100 area.
