Early 2014 13" Air: left USB stopped working after major liquid spill and subsequent tear down and cleaning. After the “accident” I inverted the computer and dried with a large fan for 48 hours. Then tore down the machine, removed the I/O card and gave it thorough cleaning with Isopropyl. Luckily after reassembly and for 1 more day everything working fine. But today, day 3 following cleaning, left USB stopped working. I’m ready to replace the I/O board and have one ordered. But wanted to see if the community has any other suggestions before I proceed with the replacement.
Try an I/O board, check the I/O cable for burnt pins and also the I/O port on the logic board. Check the bottom of the board for liquid too, since there are some components which are for the external USB port on the I/O board.
I have a 2014 Lexus is250 and a liquid just fell in my USB ports and now it smells burnt and I even noticed that it was a bit burnt, it doesn’t charge my phone and now I am just scared and do not know what to do because I do not know if it will ever work :( please help
