• Did this happen after a recent window or software update?

While you respond to that, let's try these steps:

3. On the BIOS Setup screen, press F9 to select and load the BIOS Setup Default settings.
4. Press F10 to Save and Exit.
5. Use the arrow keys to select Yes, then press Enter when asked Exit Saving Changes?
6. Follow the prompts to restart your computer.

Next, uninstall Keyboard from device manager:

1. Use shortcut keys Win + X on Windows 10.
2. Select Device Manager.
3. Expand the entry. Right-click the Keyboard and select Uninstall device.
4. You may need to check the option Delete the driver software for this device, and then click the Uninstall button.
5. Reboot the computer. and check for the issue.
