Connection failure can cause a keyboard to become unresponsive. To ensure proper connection, turn off your PC and disconnect the keyboard cable from the port. After waiting a few minutes, reconnect the cable into the port, turn on PC and begin to use the keyboard again.
Faulty Port Pins
Inspect ports for a bent or broken pin. Often the specific pin is able to be bent back to the proper angle, and if it can’t be adjusted, a new keyboard/ or port will be needed.
