Lenovo Carbon X1 gen 3 USB mini DP board
 

Hello guys,

I am looking for a schematic (and possibly boardview) for the little USB/DP board of the carbon X1. I can't seem to figure out what's wrong with it. Friend of mine brought it in after some magic smoke escaped from the port. I already ordered a replacement board but I'd like to practive on the old one and try to figure out whats wrong with it.
