Dear all,

I'm trying to fix an Apple A2179 (820-01958).

The laptop had water poured over it while it was on. The audio board was corroded. The VBUS pins on the connector were completely eaten away. The main board shows no signs of corrosion, but most likely was also exposed to water. Also the water corrosion on the audio board might have led to damage on the main board.

I tried first to check all pins coming from the audio board to the main board using the component tester of a Hameg HM303-6 to see if there is any damage. All looks fine. I see protection...

From time to time I try to fix some stuff. For myself and sometimes for some family members. Sometimes more successful, sometimes less. For a living I currently do ASIC design. This forum is an amazing source of knowledge when it comes to repairing things.
