8. Troubleshooting
If you encounter issues with your ACASIS 40Gbps Docking Station, please refer to the following common troubleshooting steps:
- No Power/LED Off:
- Ensure the power adapter is securely connected to both the docking station and a working wall outlet.
- Verify the power outlet is functional by testing it with another device.
- No Display Output:
- Check that the display cables (e.g., HDMI, DisplayPort) are securely connected to both the docking station and the monitor.
- Ensure the monitor is powered on and set to the correct input source.
- Verify that your laptop's display settings are configured correctly for external monitors (e.g., extended, mirrored).
- Try connecting a single monitor first to isolate the issue.
- For Apple M1/M2 chips, remember that dual extended display is not supported.
- Peripherals Not Working (USB, SD/TF, Ethernet, Audio):
- Ensure the peripheral is properly connected to the correct port on the docking station.
- Test the peripheral directly with your laptop to confirm it is functional.
- Restart your laptop and the docking station.
- For Ethernet, check network cable and router connection.
- Slow Data Transfer Speeds:
- Ensure you are using the provided 40Gbps cable to connect the dock to your host device.
- Verify that your host device supports Thunderbolt 4/3 or USB 4 for optimal speeds.
- Check the specifications of your connected storage devices (e.g., SSD, flash drive) as their speed may be a limiting factor.
- Laptop Not Charging:
- Confirm the docking station is receiving power from the 120W DC adapter.
- Ensure your laptop supports charging via its Thunderbolt/USB-C port.
- Some laptops may require their original charger for full-speed charging, especially high-power models.
If the issue persists after trying these steps, please contact ACASIS customer support.
