Symptoms
A message appears during POST if a Dell Thunderbolt docking station is connected to a non-Thunderbolt USB Type-C port (See Figure.1) on any commercial Dell laptop. (WD19TB, WD19TBS, or WD22TB4.) Pressing the F1 key allows the laptop to boot normally. (See figure.2)
(Figure.1 Non-Thunderbolt USB Type-C port)
(Figure.2 Error Message The Docking Station you have connected cannot provide full functionality while connected to the current port. If you have a Thunderbolt port, attach the docking station to that port for full functionality.)
The error message informs you that you should not expect Thunderbolt 3 connectivity from the dock. This is because it is not attached to a Thunderbolt port on the computer which it is attached to.
