Got in a liquid damaged 3462.
trackpad connector cable had corrosion and looked like pp5v_s4_cumulus was eroded away on the cable. next to smbus_smc so i suppose it had affected that line too. Did ASD and its showing th1H SMC IO failed.
Checked U5550 and its good.
Resistance on R5550, R5551 and R5552 is also good. R5550 seems to bounce around a lot but compared with another board and it seems to match up can you confirm that?
any ideas? should i be looking into the smbus_smc line?
When it powers on fan is normal and then at about a quarter way through the osx boot up fans slowly turn to full.
