6. Troubleshooting
If you encounter issues with your Yottamaster Thunderbolt 3 Dock, refer to the following common problems and solutions:
- No Power/Indicator Light Off:
Ensure the power adapter is securely connected to both the dock and a working power outlet. Try a different outlet if necessary. - No Display Output:
Verify that the Thunderbolt 3 cable is correctly connected to both the dock and your laptop. Check display cables (DisplayPort, USB-C to display) are securely connected to both the dock and the monitor. Ensure your laptop's display settings are configured to detect and extend/mirror displays. Confirm your laptop supports the desired display resolution and refresh rate. - SSD Not Recognized:
Ensure the M.2 NVMe/SATA SSD is correctly installed and secured within the enclosure. For new SSDs, it may need to be initialized and formatted through your operating system's Disk Management (Windows) or Disk Utility (macOS). - Slow Data Transfer Speed:
Ensure you are using a certified Thunderbolt 3 cable. Verify that your laptop's port is a Thunderbolt 3 or 4 port, not just a USB-C port. Performance can be affected by the type and speed of the SSD installed. - Peripherals Not Working:
Try connecting the peripheral to a different USB port on the dock. Ensure the peripheral has necessary drivers installed on your computer.
If the issue persists after trying these steps, please contact Yottamaster customer support for further assistance.
