MBA 13", early 2014. MD760. A1466 820-3437-B Spilled liquid all cleaned off OK and carefully dried for 3 days. Will startup OK *only* if the left I/O ribbon is removed. Connecting the ribbon after boot up puts laptop to sleep, remove ribbon, touch power button and wakes back up! All keys on keyboard functioning correctly. Will not charge, mag power led off. Any suggestions? I have main schematic and board layout. Need schematic for i/o board. PS - not my mba, it's the daughter's!
