Hi Inder,
Welcome to Microsoft Community.
I'm sorry to hear you're having trouble with your Surface Dock.
Would you describe your issue in more detail? Are all devices not working properly with the dock, or are there specific features (e.g., video output, USB ports, network connections) that are having issues? What model of Surface Dock are you using, and what model of Surface or other brand of laptop are you using with it?
You can refer to this link to conduct preliminary troubleshooting based on your specific problem. [Troubleshoot Surface Dock or Surface Docking Station - Microsoft Support] With more details, I can give you a more precise solution!
Please note that my initial response may not resolve your current situation immediately. However, with your help and more detailed information, we can work together to find a specific direction for your current situation.
I hope this helps. If there is anything not clear, please do not hesitate to let me know.
Your Sincerely
Hahn. W - MSFT | Microsoft Community Support Specialist
