Check your connection on your laptop. If your laptop has connections, as pictured below, plug in as follows. Do NOT use the USB-C connector. Use the Thunderbolt connector. This connector is disguised and not dedicated. Once this is plugged in, your docking station will function normally.

Plug in the rear of the dock. The cable with the 3 on it is the Thunderbolt 3 cable. Make sure the 135-watt power cable is plugged into the correct port.
