Hi. I spilled about a half cup of coffee on my Macbook Air. As soon as it happened I turned it upside down and shut it off. After letting it sit for a while I turned it on and everything works fine except the charging. I have no light at all on the magsafe and the battery will not charge. When I plug it up it shows that’s it’s plugged in on the status bar and will run on the charger but the battery is not charging. I have cleaned the logic board and the DC board with alcohol and after putting it back together it’s the same. I would really appreciate some advice I’m hoping it may be the DC board as I can’t afford the logic board. I also didn’t see any coffee or anything sticky on the logic board. Actually very little coffee got into it. Thank you for your time! Macbook Air mid 2013 11"
Check the function of all your keys to see if it needs a top case replacement. Your diagnosis sounds correct. Try replacing the magsafe board and see if it solves your problem.
