How to use

Connect the docking station to AC power using the supplied 135W adapter.

Connect an external monitor to the HDMI port if required, and plug a network cable into the RJ-45 port for wired internet access. Use the available USB ports for peripherals such as mouse, keyboard, storage devices or other accessories. Ensure your system runs a supported operating system (Windows 10, Windows 11 or Windows 7) and install any required drivers if the host OS prompts for them.

Recommendations

For stable network performance, use a high-quality Ethernet cable and avoid long runs that could degrade signal. When charging a laptop via USB Power Delivery, verify that the host device supports PD at the required wattage. Keep the docking station on a flat, ventilated surface and avoid obstructing any vents to maintain safe operating temperatures.
