Maybe the Airpad has a surface mounted fuse(?) If so, it will probably look like a chip resistor and likely be very near, and on the circuit trace from the center pin of the power connector. Perhaps "depot" will know if the AP is fused on the external power input.
Armed with that information you could try and replace it. I would not reccommend soldering a fine wire (aka "magnet wire") short across the open fuse, as that would be unsafe.
