See “Running the Diagnostics” on page 47 for details.
1. Run the system board test to verify the symptom.
This test verifies the system board. If no error is
detected, return to “Checkout Guide” on page 26.
2. If FRU code 10 appears, replace the system board.
3. Rerun the test to verify the fix.
If this procedure does not correct the problem, go to
“Undetermined Problems” on page 46.
TrackPoint III Checkout
If the TrackPoint III does not work, check the configuration
in the ThinkPad Configurations program. If the
configuration of the TrackPoint III is disabled, select
Enable to enable it.
If this does not correct the TrackPoint III problem, continue
with the following.
The TrackPoint III adjusts the pointer sensor automatically.
During this process, the pointer moves on the screen
automatically for a short time. This self-acting pointer
movement can occur when a slight, steady pressure is
applied to the TrackPoint III pointer. You must readjust it if
the temperature has exceeded its normal temperature
range. This symptom does not indicate 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 screen.
2. Select an item with the pointing stick.
3. Press either the left or right click button.
4. Verify that both 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:
Reseat the keyboard cables.
Replace the keyboard.
Replace the system board.
