Please note that not all USB-C ports on a computer support charging. Verify if your computer supports Power Delivery (PD) over USB-C and also identify which port has this functionality (if multiple USB-C ports are available).
Otherwise, please check that the docking station is powered on. Depending on the model of the dock, you should see a blue or white light which indicates the dock is powered.
