Hi, I'm new to this forum, but I'm looking for some help on how to fix my Macbook Air Mid 2013 Model A1466. Last week, my computer experience some water damage from a leaked water bottle in my backpack. I took it to the apple store and they told me that nothing was covered under warranty and told me the only option was to pay 750 + tax to fix the computer(doing whatever was necessary to fix it). My computer turned on so I didn't think that there was much water damage or at least less than 750 dollars. Having some prior experience with laptops before(although never water damage), I decided to try some steps I found online. Not wanting to risk taking apart the whole computer, I just cleaned some corroded parts (only two specific parts seemed visibly corroded) of the logic board/magsafe board with isopropanol and dried it under a fan; it seemed to turn on and work, however, battery would discharge and the charger would work, but the battery would not charge. Also, there was no sound output and the internal speakers were not detected. I thought maybe I needed a new magsafe board because the battery would not charge and because the speakers were connected to the board. Seeing as how there wasn't much for me to lose, I decided to take apart the whole computer and wash the logic board/magsafe board with high concentration isopropanol. I noticed that I had missed some corroded sections on the the underside of the boards that I could not reach before. I let the boards dry and reassembled the computer. I connected all of the wires, plugged in the charger, and it seemed to solve the battery charging issue. I am able to charge my battery regularly without any issues. However, I still have a problem with the sound. My internal speakers don't seem to be detected. Also, earphones were not detected by the computer either. What do you think I should do in order to fix the computer most efficiently? I also factory reset the computer to check if it could be a software issue. Do you think that it could be a simple swap of the speakers? magsafe board? or the actual logic board? I'm not sure where to begin because I don't know where everything is located. Thank you in advance for the help!
