Hey, so I mostly think this is a problem with the stupid MS surface my wife uses for work, but here goes:
1) bought a ugreen dual HDMI docking station for my office, but tested it at home, and it worked, and just going on memory, but I swear it worked with my wife MS surface as well (including charging, but I can't be sure I'm remembering this correctly.
2) bought a 2nd Ugreen docking station to use at home, has "100W pass through", and connects fine to wifes MS surface, displays both monitors fine, but is NOT charging that MS surface machine. Have a 65W charger putting power into the dock.
3) her MS surface charges just fine on USB C lenovo power cord, so that port will accept power.
Thoughts? Do I need a higher wattage power source, is the MS surface just not recognizing this dock as a charge source? Do I have a bad dock?
Naturally my wife started messing around with this as I was on my way out the door, so I didn't have time to do any real diagnostic work.
Next steps?
