Why is my keyboard not working

@sifisomoloi could be a failed keyboard or a bad keyboard connection. Also, if you are using Windows, check the driver for the Keyboard. I would even go ahead and remove the driver and then reinstall. Just to make sure this is not caused by a weird software issue. Once you rule out the software, time to open up your computer and have a look at the keyboard cable and connector. Make sure the cable is well connected and not tears and no corrosion on the connector. If all that checks out okay, consider replacing the keyboard.

Now, for any help opening your computer and possibly even replacing the keyboard, we will need to know the exact model number for your computer.
