Mac Air had a few drops of water spilled on keyboard. I opened it and saw slight corrosion on U7090. So far only cleaned it with a brush and alcohol.
Measuring voltages Here's what i'm seeing:
PPDCIN_G3H is giving me 15v (though it cycles between 14.9 to 15.0)
I also get 15v at the magport and dcin on the board, and also at PP18V5_DCIN_ISOL_R.
I thought those were supposed to be 18.5V?
Also, on PPBUS_G3H i only get 3mV @ R7006 which i think should be 8.6V?
Any ideas where to check next? I'm a beginner, so appreciate all the help.
