    • Verify the power outlet is functional.
    • If your dock has an ON/OFF button, ensure it is pressed to the 'On' position.
  • Display Not Working or Flickering:
    • Confirm that the Thunderbolt 4 cable is securely connected between the dock and your host device.
    • Ensure your host device's USB-C port supports DisplayPort Alt Mode.
    • Check display cables (DisplayPort) are firmly connected to both the dock and the monitor.
    • Try a different display cable or port on the dock/monitor.
    • Update your graphics drivers on your host device.
    • Adjust display settings in your operating system.
    • If using multiple displays, ensure the combined resolution and refresh rate do not exceed the dock's capabilities (e.g., 2x 4K/60Hz).
  • USB Devices Not Detected:
    • Ensure the USB device is properly connected to the dock.
    • Try connecting the USB device to a different USB port on the dock.
    • Connect the USB device directly to your host device to verify its functionality.
    • Restart your host device.
  • No Network Connection (LAN):
    • Verify the Ethernet cable is securely connected to the dock's 2.5GLAN port and your router/switch.
    • Check the network status lights on the dock and your router/switch.
    • Ensure your host device's network settings are configured correctly (e.g., DHCP enabled).
    • Update network drivers on your host device.
    • Some operating systems might default to lower speeds for the Ethernet port. Check your network adapter settings to ensure it's set to 2.5 Gbps or "Auto Negotiation".
  • Host Device Not Charging (Power Delivery):
    • Confirm your host device supports USB-C Power Delivery via its Thunderbolt 3/4 or USB-C port.
    • Ensure the Thunderbolt 4 cable is connected to the correct upstream port on the dock and your host device.
    • Verify the power adapter is connected and working.
