  The system fails to respond to keyboard entries.

  This problem is most likely caused by a faulty keyboard, keyboard adapter, or keyboard cable.

  Try the FRUs in the following order. Test each FRU by retrying the failing operation.

  1. Keyboard.
  2. Keyboard adapter, typically located on the system board.
  3. Keyboard cable, if not included with the keyboard.

  3. If the system does not have a graphic adapter POST, go to the display's problem determination procedures. If you do not find a problem, replace the graphics adapter.
