2. KEYBOARD NOT WORKING The most common problem when you have a keyboard that is not working is an bad connection. Try reconnecting your keyboard, restart your computer and see what happens. Turn off the system. Unplug the keyboard connect and look for any bent or broken pins. If the pins are bent, then it is possible to kindly make straight them using the tip of a pen or mechanical pencil. If the pins are broken, then replacement of the keyboard may be necessary. If none of the above steps resolves your keyboard problem, it is likely that your keyboard is bad or it is really old.
