Based on the symptoms already checked, the supported next steps are:
- Verify the basic hardware path again:
- Unplug the USB receiver, wait a short time, then plug it back in.
- Try a different USB port.
- If the receiver is connected through a USB hub or dock, remove the hub and connect it directly to the PC.
- Check that the keyboard batteries are fresh or fully charged.
- Make sure there is no dirt or blockage affecting keys or sensors.
- Re-establish the wireless connection:
- For USB wireless devices, unplug the USB wireless receiver, wait about 10 seconds, and plug it back in.
- If the device has a Reset button on the keyboard or USB receiver, use it to disconnect and reconnect the wireless connection.
- Test whether the keyboard hardware itself still works:
- Connect the keyboard and receiver to another PC.
- If it does not work on another PC either, replacement may be necessary.
- When testing on another PC, make sure the correct driver is installed if the device requires one.
- If the keyboard is detected but does not behave correctly in Windows 11:
- Open Start > Settings > Time & language > Region & language and confirm the keyboard input language matches the PC display language.
- Open Start > Settings > Update & Security > Windows Update and confirm the PC has the latest updates.
- If special keys or custom behavior are the issue rather than basic typing:
- Open Start > Settings > Devices > Mouse to review mouse-related settings.
- Microsoft Mouse and Keyboard Center is used only for supported devices, so “no supported devices were detected” indicates the app is not recognizing this keyboard as a supported model.
Since Windows already detects the dongle as an HID keyboard device and the keyboard still does not function after re-pairing attempts, forcing a different driver is not supported by the provided guidance. The most decisive check is testing the keyboard on another PC. If it fails there as well, the hardware is the likely cause.
