Water Damage, Battery not charging. Worked until battery drained
My Mum dropped some coffee on top of her Macbook Air. I managed to open it, dry it and cleant it with Isopropyl Alcohol 99%. After a few days of drying the computer booted up but I never got it to charge the battery or work with AC Adapter. It worked until the battery was drained and nothing has happened ever since.
Any ideas on where shall I start testing? I already bought a new IO Board which didn't work so it's clearly not that.
I got the schematics of the board but I have no idea where I should start testing. Does someone has any idea?
