I would love to see the look on the face of the guy at the Apple Store when OP pulls out the multimeter. No disrespect, but in my experience they're good at handling common issues and terrible when you have something unique.

Yep, I laughed when the only response on that forum thread was “take it to the Apple Store”.

I doubt anyone in there would even know how much voltage should an USB port deliver.

I guess he can prove his point by asking the Apple people to plug their iPhone into the laptop and watch the thing catch fire.
