Running the Diagnostics 2. If FRU code 10 appears, replace the system board but do not replace the CPU card. Remove the CPU card from the old system board and install it 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 the "Undetermined Problems" section for each model. TrackPoint Checkout If the TrackPoint does not work, check the configuration in the ThinkPad Configuration program. If the configuration of the TrackPoint is disabled, select Enable to enable it. If this does not correct the TrackPoint problem, continue with the following. After you use the TrackPoint, the pointer drifts on the screen for a short time. This self-acting pointer movement can occur when a slight, steady pressure is applied to the TrackPoint pointer. This symptom is not a hardware problem. No service actions are necessary if the pointer movement stops in a short period of time. If a click button problem or the pointing stick problem occurs, do the following: 1. Go to the Easy-Setup menu. 2. Select an item with the pointing stick. 3. Press any one of the click buttons. 4. Verify that the item is selected. 5. Move to another item with the pointing stick. 6. Press the pointing stick (press-to-select), and verify that the item is selected. Note: This step is only for the model that has the press-to-select function. 7. Verify that all buttons work correctly. If either the pointing stick or the click button do not work, do the following actions one at a time to correct the problem. Do not replace a nondefective FRU. 1. Reseat the keyboard cables. 2. Replace the keyboard. 3. Reseat the card that the TrackPoint cable is directly connected to. 4. Replace the system board.
