Given the date of my docking station (2+ years old), I would be _amazed_
if it could do USB PD.  But I should go try it, my existing Dell laptop
doesn't support that, but I have an Acer here, along with some
chromebooks that do.

I guess I need to go get the latest Dell laptop, "just to test" with :)
