To give some backstory on this MacBook Air had water spilled on it, the person who spilled the water had put the laptop in a tent position waited for probably an hour then tried to attach the MagSafe cable and power on repeatedly.
After no success he gave up, and I offered to attempt to fix it for him. There was minor corrosion in multiple spots of both the logic and I/O board as well as the CPU heatsink thing.
I remove all those parts and put them in a ultrasonic cleaner with distilled water and 5% elma tec S1 solution at 62 degrees Celsius for 2 minutes. It appears that had removed the corrosion, inspected the logic board closely for any signs of discoloration/damaged pins and it looked good to me (also reapplied thermal compound to attach the heatsink).
I then checked the I/O board and where there was previously corrosion I saw there was a somewhat burnt discoloration on the board itself. After the ultrasonic cleaning I used a Multimeter on it to check connectivity throughout the board (I honestly didn’t have much of an idea what I was doing with the multimeter in terms of understand what I was suppose to interpret).
I will post some images of what the I/O board in question looks like and possible a pic of the logic board itself, thanks for the help in advance.
