Hello Mike,
Thank you so much for posting in Microsoft Community.
I appreciate you raising this concern and I understand that you're having issues with your Surface Keyboard.
You got me here; we'll definitely sort this out together. Before anything else, allow me to ask a question:
- When your Surface booted to UEFI, does the keyboard works there or not?
For now, let us do some other troubleshooting steps that could help us to isolate this issue:
- Check for Windows Update. Go to Settings >> Update and Recovery >> Windows Update >> Check for Updates >> Install >> Restart.
- Disconnect and reconnect the keyboard.
- Run Surface Diagnostic Toolkit - Microsoft Apps
- reinstall keyboard driver. Go to Device Manager >> Keyboard >> double click the keyboard driver or long press >> Select Uninstall >> Restart.
- Check if it has been disabled. Go to Device Manager >> Keyboard >> double click the keyboard driver or long press >> if the option says enable, that means keyboard is disabled >> click enable.
- Download Drivers and Firmware: Download Surface Pro 6 Drivers and Firmware. from Official Microsoft Download Center
- Boot your Surface to UEFI again and see if the keyboard works there. If any case it works, there is a software issue that can be solved by resetting the Surface. See this link for the steps: Restore or reset Surface for Windows - Microsoft Support
On the other hand, if the issue persists in UEFI, there is likely a hardware issue of it that the best thing to do is to create a replacement/repair order to it. However, when it comes to this kind of issue, this is already beyond of our scope as we don't have the necessary tools for that. The best I could do is to refer you to our live supports, to contact them, see steps below:
