    There is no magic sauce to it, you just have to start following the traces from the DC-plugin and testing each and every component along the way, replacing the ones that aren't working as they should. I'd probably check continuity from the connector to the CPU first, though, as if the components along the way have shorted the damage will have reached the CPU and there's nothing you can do to rescue it.

    My Solution, order new up board... (unfortunately been there, done that)

    My visual checking of my board I found that at least one chip that was near USB was damaged (small crater in it). Not sure what else. Also I think it damaged the Wifi adapter I had plugged into usb.... I tried it later and it was at least sort of working, but it was getting very hot to the touch...
