a	moment	soon	after		the computer is	powered on.
Make sure		they		turn	on.

If the problem persists, replace the system board.

System Board and CPU Card Checkout

The system board and the CPU card FRUs perform the operation on the computer. Processor problems can be caused by either FRU. Generally, the CPU card has a lower failure rate. If a numeric code indicates the system board or the CPU card 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 card. If no error is detected, return to “Undetermined Problems” on page 32.

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 card. Transfer the CPU card from the old system board to the new system

	board.
3.	If	FRU	code	11	appears, reseat the CPU card.
4.	Rerun the test to				verify	the fix.
5.	If	FRU	code	11	remains,	replace the CPU card.

If this procedure does not correct the problem, go to “Undetermined Problems” on page 32.

TrackPoint Checkout

1.Run the ThinkPad Configration program and check if the TrackPoint is enabled.

2.If it is not,Enable selectand enable it.
