    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!

    Sound like the liquid damaged the LIO board. Pretty straight forward. And the machine won't charge because the IO board has to be unplugged to boot. The MagSafe connector is on the IO board.

    Sounds like you just need to change the Left IO board. They are pretty cheap.

    Many thanks for your thoughts. That was my gut feeling but I'd like to prove it as getting the board in the UK costs a minimum of $60 plus (if unlucky) import duty & 20% tax! This machine is so new that parts are still fairly rare.

    No charging takes place even with the ribbon connected and I assume an MBA normally charges while asleep.

    I had to buy it like everyone else so I'm afraid you will have to do the same:

    from

    getnotebookschematic.com

    If you need an I/O board I have a good one for sale that I didn't need.

    Good luck!
