System Board and CPU Mini-Cartridge Checkout

The system board and the CPU mini-cartridge FRUs perform the operation on the computer. Processor problems can be caused by either FRU. Generally, the CPU mini-cartridge has a lower failure rate. If a numeric code indicates the system board or the CPU mini-cartridge as failing, do the following procedure to isolate the problem:

1.  Run the system board test to verify the symptom.  This test verifies both the system board and the CPU  mini-cartrige. If no error is detected, return to 'Undetermined Problems'.

   NOTE: Do not touch the keyboard and the pointing  device when the system board is being tested.  This might cause unexpected errors.

2.  If FRU code 10 appears, replace the system board,  but do not replace the CPU mini-cartrige. Transfer  the CPU mini-cartrige from the old system board to  the new system board.
3.  If FRU code 11 appears, reseat the CPU mini-cartridge.
4.  Rerun the test to verify the fix.
5.  If FRU code 11 remains, replace the CPU mini-cartridge.
