My friend's MacBook Air had a little tequila and now is hungover and not booting up. It doesn't chime either (POST), so I am suspecting that the logic board will need to be replaced. I connect a power supply to it and the light turns orange, and when I disconnect the battery and reconnect the power cable, the light turns green. That tells me that the I/O board is working correctly, right? My next guess is that the power button is not functioning, but I am not sure if that is part of the logic board or not... Can someone let me know if I need to go the full monte on this thing and repair or replace this logic board? Or am I overlooking something simple?

thanks in advance!

I guess my question should be more specific... How can I know for sure that it's the logic board that is the problem? If I have already replaced the I/O board, and the power supply works fine to boot another computer, is that the next logical thing in this machine for me to replace if I am getting no POST? Or is there a way to replace the power button without replacing the entire logic board?
