TrackPoint III Checkout
If the TrackPoint III will not work, check the configuration in
the ThinkPad Features 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 steps.
The TrackPoint III does automatic compensations to adjust
the pointer sensor. 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
while the computer is powered on or while the system is
running, or when re-adjustment is required because 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 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 non-defective FRU.

Port Replicator Game Port Checkout
Do the following if a Port Replicator joystick problem
occurs:
1. Connect the joystick to the Port Replicator game port.
2. Go to the Easy-Setup screen.
3. Select an item with the joystick.
4. Press any button of the joystick.
5. Verify that all buttons work correctly.
If either the joystick or a button does not work, replace the
Port Replicator. If the problem still remains, replace the
system board.
Diskette Drive Test
Do the following to isolate the problem to a controller,
drive, or diskette. A scratch, write enabled, non-defective
2HD diskette is required.
