How to Fix USB Keyboard Not Working But Mouse Does
You should follow the below steps to solve your USB keyboard that isn’t working:
Unplug and Plug Again
The first and most common method that you should try is to unplug and replug the keyboard into the motherboard.
Sometimes the keyboard cannot be connected securely to your PC and it prevents the device from recognizing it.
So, you should carefully unplug it from the USB port and wait a few seconds. Then plug the keyboard back into the USB port firmly.
Faulty Keys
Another possible cause for this problem can be faulty keys of your keyboard. It is possible that the keys you are using/pressing are faulty.
So, the faulty keys lead you to the keyboard issue. So, you should check all keys from the keyboard to ensure whether a few keys are not faulty.
You can test your keyboard using offline/ online keyboard testing softwares. And check if one of the keys are functioning.
Check USB Port
When your USB keyboard isn’t working it can be caused by a malfunctioning USB port on your motherboard.
So, in this situation you should carefully inspect theUSB port and ensure it isn’t clogged or broken.
If you find a build up of dirt inside the port, you should clean it to solve the problem. In order to clean the USB port you can use compressed air, toothbrush or rubbing alcohol.
Check With Other Device
If the port is clean but the keyboard is still not working you should check it with your friend’s computer or another device if you have one.
If your keyboard works correctly with the other computer, it means that your computer isn’t compatible with that keyboard.
On the other hand you can check all other input USB ports from your computer. Plug the keyboard into each port individually and check if it respond.
