TP 380,385 - Trackpoint III Checkout
Applicable to: World-Wide
The following information is intended for IBM Dealers and Authorized Servicers only. Customers attempting to follow any of the procedures below may void their warranty.
TrackPoint III Checkout
If the TrackPoint III does 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:
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 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 does not work, do the following actions one at a time to correct the problem. Do not replace a nondefective FRU.
Reseat the keyboard flexible cables.
Replace the keyboard.8
Replace the subcard.
Replace the system board.
