TP 310,315 - Trackpoint III Checkout
Applicable to: World-Wide
TrackPoint III Checkout:
The TrackPoint 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 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. Boot from the diagnostics diskette and start the PQA program (please refer to "Running PQA Diagnostics Program" on page 30 of the HMM.)
2. Go to the diagnostic Manual Test menu.
3. Press F2 in the test items.
4. Press the left and right click buttons.
5. Use the pointing stick to move the cursor to the 4 corners.
If either the pointing stick or the click button does not work, perform the following actions, one at a time, to correct the problem. Do not replace a non-defective FRU.
- Reseat the keyboard flexible cables and the TrackPoint flexible cable.
- Reseat the flexible cable connecting the TrackPoint board via the system board.
- Replace the TrackPoint board (under the click buttons).
- Replace the keyboard.
- Replace the system board.
