My macbook air, wont charge, I plug in the Power supply and no light comes on the magsafe plug, I can hold the power button and after a few seconds it CHIMES, you can see the back light on the screen, but it stays black. After a few minutes I get the file with the question mark. Is my logic board dead? I run the Internet repair (only option) and It doesnt see my HD. I ran a diagnostic, and It says it cant see the battery, It cant see the HD, and a few other error. I fear the worst. Any information would be helpful.
It sounds like you have two issues here. The first is your MagSafe charger is not working correctly, either the charger is bad or the I/O board within your system.
