Hi I left the Mac on sleep when I went to work and when I came back I couldn’t turn it on. There was plenty of battery when I left but it’s not turning on. There was no liquid or physical damage to the laptop. When I plug the charger on, the green/orange indicator doesn’t turn turn on. This happened once before and I left the Mac plugged in, when I came back I could see it’s charging and all was back to normal. But when I tried to do the same thing this time it didn’t work. i checked the power adapter with a voltmeter, and I can see it’s working fine, i also took off the back cover and I checked the terminals on the circuit. And I can see still there’s power flow. But the charge indicator is still not working. I tried doing the SMC reset with out plug in and with, still no response. I tired disconnecting the battery and reconnecting, without a response i tired turning on with the battery disconnected, again without response. Whats should I do here, what do you guys think that’s wrong with the Mac and how to troubleshoot it
Sounds like your I/O board has failed MacBook Air 13" (Mid 2013-2017) I/O Board and here’s the guide MacBook Air 13" Mid 2013 I/O Board Replacement Otherwise the charging logic within the main logic board has issues. Update (07/31/2019) DC-In Board header
