TrackPoint III Checkout
If the TrackPoint III does not work, check the configuration
in the ThinkPad Configuration 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 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 readjustment 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 menu.
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 does not work,
do the following actions one at a time to correct the
problem. Do not replace a nondefective FRU.
