D3000 video and Ethernet no longer functioning on W8.1 with Dell XPS 13

Molds,

I am aware of older Dell 3000 docks having a possible hardware issue, but most often it is the older XPS13 i.e. LS321. Post the complete CY... number of the dock and I can check it, post the Service Tag and I can check the PC for you.
