If its just folded back, then you could de-solder the connector, fold the pin back and re-solder it. Even if the pins has broken off (quite unlikely, but it happens), its probably possible to solder a wire to the stub, and still repair it.
Its also possible that if you re-heat the hole with the non protruding pin, and add a bit of solder the pin will connect, not nice but that often works, so its worth trying that first.
P.S. because it the power pin, make sure before testing it that the added solder didn't shorten the power pin to another pin or ground, use a multimeter between the pins to make sure it didn't.
