What to Do If the Keyboard Test Fails
Try these steps to diagnose and fix common keyboard errors:
- Check the connection. Ensure the keyboard cable is firmly plugged in. If it is a USB keyboard, try different USB ports on the front and back of the PC. For wireless keyboards, re-seat the USB receiver and replace the batteries.
- Detect and fix device errors. On Windows, open Device Manager → Keyboards, right-click your keyboard and choose Update driver or Scan for hardware changes. You can also run the built-in Keyboard troubleshooter from Settings.
- Reinstall or update the keyboard driver. In Device Manager, uninstall the keyboard device and restart to reinstall automatically. You can also check Windows Update and your PC/laptop manufacturer’s support page for the latest driver. If you prefer a third-party updater, you may try Driver Booster to scan for outdated drivers. Create a system restore point before using any third-party tool and decline extra offers.
