I'm trying to repair the power connector for a surface pro 3 (the part that mates with the computer, not the power brick). Obviously normally they're not worth repairing, and you'd just buy a new one, but I'm in a unique situation: I'm at the South Pole, where there is absolutely no mail service or package delivery until November, so ordering a new one isn't possible. My friend here has a Surface Pro 3, and only one power cord (no one here has a spare). The contacts on the connector he has are severely corroded, and I'm trying to fix it for him (or butcher the existing connector for parts to make a hacked-together new one) so he doesn't have to do without a computer until November. But that leaves me in need of a wiring diagram or some kind of spec sheet for the connector. Alternatively, does anyone know if it will charge (even verrrrrrry slowly) via the USB port?
