Hello, we had some liquid (cranberry juice I was told later) spilled on my daughter’s MacBook Air and we did our best to clean it up as quickly as possible without disassembling the machine. The device worked fine for about one month and then it popped up with the “question mark folder” and will not boot at all now. We have done a recovery boot and the system does not show the storage device installed. I have removed the I/O board and found some residue on it that I cleaned as well as inspecting the other components. Is there anything else out there that I’m not doing that I can try before I try to decide which component need replacing? Thank you.
When it comes to liquid contact, the most important thing is to cut power as soon as possible. The longer the device has electricity running through it, the higher chance of a short circuit and the more damage will be done. First, shut the laptop down and unplug it immediately. Using this guide, disassemble the device and remove the logic board and other major components. Wipe them down/immerse them with 90%+ isopropyl (rubbing) alcohol. Let them sit out in front of a fan for 48 hours, or longer if they need more time to dry. Once you are certain that they are thoroughly dry, reassemble the device and try to turn it on. Then, let us know the results when you are at this point and we can troubleshoot any possible part failures and what can be done in terms of repair.
