Hi Jarryd,
Welcome to Microsoft Community.
I'm Hahn and I'm here to help you with your concern.
I'm sorry to hear about the trouble you're having with your Surface Pro 8 keyboard. Let's try a few steps to resolve this issue:
- Detach and Reattach the Keyboard:
- Unplug your Surface and detach the keyboard cover.
- Make sure there is no debris or damage on the connectors.
- Reattach the keyboard, ensuring all magnets touch the bottom edge of your Surface.
- Force a shutdown and restart your Surface: Force a shutdown and restart your Surface - Microsoft Support
- Manually update Surface drivers and firmware: Download drivers and firmware for Surface - Microsoft Support
- Confirm connectivity:
Press the Caps and Fn keys on your Surface Type Cover or Keyboard several times to check whether the LED lights turn on.
If the LED lights turn on, your problem may be with Windows and not the device itself. The next step is to reset your Surface. Here's how:
- Go to Start , enter reset in the taskbar, then select Reset this PC .
- Select Reset this PC > Keep my files > Cloud download and follow the rest of the prompts shown on screen. For more detailed steps and a video, see Restore or reset Surface for Windows .
If the LED lights don't turn on, there might be a hardware issue. To verify in UEFI, do the following:
- Turn off your Surface and wait 10 seconds.
- Press and hold the Volume Up button—and at the same time, press and release the Power button.
- You'll see the logo screen on your screen. Continue to hold the Volume Up button. Release the button when the UEFI screen appears.
- Press the up and down arrow keys to change what is selected on the left side menu to check if the keys work or not.
- If the keys are working correctly in UEFI, but not in Windows: The problem is likely with the software installed on the Surface, and you'll need to reinstall. See Creating and using a USB recovery drive for Surface .
- If the keys are still not working correctly: If the Type Cover or Keyboard still doesn’t work on your Surface, submit a service order for your Type Cover or Keyboard. How to get service or repair for Surface - Microsoft Support
I hope this helps. If there is anything not clear, please do not hesitate to let me know.
Your Sincerely
