Hi, Nabiscuit!
Thanks for reaching Microsoft Community and letting us know the Surface Dock issue you have. We appreciate details you provided and we also apologize for the troubles you have to go through here in scouring for troubleshooting guides to no avail. This isn't the experience that we want you to have.
If I understand it correctly, this involves several Surface Docks and Surface devices. You mentioned there are Surface Pro 4 devices that don't have issues. Are they using their own docks? If yes, can you try to borrow it and use it on your Surface Laptop then observe it?
Let me know how it goes.
Regards,

Janette_Z,
Can we get some help here? You haven't responded to any of us, yet. It's been a week.
You guys are selling an expensive PC ecosystem that turns out to be a big bummer when it doesn't work as advertised. We could have all purchased Dells & Lenovos and saved a bunch of money... But we chose Microsoft for the product build quality, the pedigree, and the promise that you guys know what you're doing when regarding hardware compatibility with Windows.
Please get back to us and let us know what's going on with these Surface Docks.
