Keyboard not working issue and solutions

If your keyboard isn't working, there are several possible reasons, ranging from software glitches to hardware issues. Here are some common solutions:

1. Check Physical Connections

   - Wired Keyboard : Ensure the keyboard is properly plugged into the correct USB port. Try a different port to rule out the one being faulty.

   - Wireless Keyboard : Check the batteries or recharge the keyboard if it's rechargeable. Ensure the Bluetooth connection is working and the receiver is properly plugged into the computer.

2. Restart the Computer

   Sometimes, a simple restart can resolve the issue, especially if it’s related to software or system processes.

3. Try the Keyboard on Another Device

   To rule out whether the issue is with the keyboard itself, try connecting it to another device, like a different computer or laptop. If it works on another device, then the issue might be with your computer.

4. Check the Keyboard Settings (Software Issues)

   - Windows : 

     Go to Device Manager → Keyboards→ Right-click and select Uninstall. Restart your computer to let Windows reinstall the driver automatically.

     Check Keyboard Settings under Control Panel→ Ease of Access→ Keyboard Settings to ensure sticky keys, filter keys, or other accessibility features aren’t interfering.

   

   - Mac :

     Go to System Preferences → Keyboard to check settings and reset to default if needed.

5. Update or Reinstall Drivers

   - Windows :

     Right-click Start → Device Manager→ Keyboards→ Right-click on your keyboard and select Update Driver.

     If the driver update doesn't work, try uninstalling the driver and restarting the computer.

   

   - Mac :

     MacOS usually handles drivers automatically, but check for any software updates in System Preferences→ Software Update.

6. Check for Malware

   Sometimes, malware or a virus could cause hardware issues. Run a virus scan to ensure your system is clean.

7. Try Safe Mode (Windows)

   Boot your computer into Safe Mode and check if the keyboard works there. If it does, the issue may be with a third-party application or a driver conflict.

   To enter Safe Mode, restart your computer and press F8 (or Shift + F8 on some systems) before Windows starts loading.

8. Reset or Update BIOS (For Hardware Issues)

   If none of the software fixes work, try updating or resetting the BIOS/UEFI settings on your computer. This is especially helpful if the issue is related to hardware initialization.

   Be careful when updating BIOS as incorrect updates can cause issues. Check your motherboard manufacturer’s website for instructions.

9. Try Another Keyboard

   If possible, try using another keyboard to see if the issue is hardware-related. If the second keyboard works fine, then the original keyboard may need to be replaced.

10. Check for Physical Damage

   Inspect the keyboard for visible damage, such as broken keys, spilled liquids, or loose connections. If you find damage, you might need to replace the keyboard.

If none of these solutions work, you might want to consider replacing the keyboard, especially if it’s hardware failure.
