Remove the external keyboard if the internal keyboard is to be tested.

If the internal keyboard does not work or an unexpected character appears, make sure that the three flexible cables extending from the keyboard are correctly seated in the connectors on the top system board.

If the keyboard cable connection is correct, run the Keyboard Test by performing the following steps:
  1.  Power-off the computer, and then  power it on again.

     Press the F1 key any time  while the POST memory count is proceeding.  At the end of the memory test, the Easy-Setup screen screen appears.

  2.  Press the left or right arrow key to  select Test and press Enter  or position the pointer over the Test icon and  click the left click button once.
  3.  Press Ctrl+A  to enter advanced diagnostics.
  4.  Press Ctrl+K to start the keyboard diagnostics test.
  5.  Press each key.  A shaded box appears in  the corresponding key position on the  keyboard layout on the screen. Press the key again to remove the box.

    NOTE:   The shaded box appears in Fn  only during the first keyboard test of a diagnostics session.

  6.  To exit from the test screen, press Esc.

If the tests detect a keyboard problem, perform the following tasks one at a time to correct the problem:

NOTE: Do not replace a nondefective FRU.

The following auxiliary input devices are supported for this computer through the MultiPort II:

If any of the above devices do not work, reseat the cable connector and repeat the failing operation. If the problem does not reoccur, recheck the connector. If the problem reoccurs, repeat the operation with a device that is known to be good. If the problem still reoccurs, go to 'MultiPort II Checkout'
