Dead MBA, but not the motherboard - ideas?
We heard a loud humming noise coming from the next room where this MBA was, and I actually don't know if it was coming from the attached speakers as I assumed, or from the MBA itself. Moments later it died, never to be woken again.
I jumped right to the motherboard solution based on my local repair shop, who doesn't do this kind of work. But after replacing the motherboard, still dead. I didn't have any extraordinary difficulties with the transplant, and went slow and careful on the reassembly, so I think it's unlikely that's the cause.
A bad replacement board is possible but also seems unlikely. So, any other components that would be good candidates for this?
Only other symptom besides "dead" would be that the magsafe connector does not light up when plugged in and attached.
Is this a good question?
