If the TrackPoint III does not work, check the configuration in the Configuration Utility by
pressing PgDn to reach the
I/O Management screen.
If the setting for TrackPoint III is Off,
press the left or right arrow to change
it to On.
If this does not correct the problem, continue
with the following procedure:
NOTE:
The TrackPoint III performs automatic compensations to adjust
the pointer sensor.
During this process, the pointer moves about the
screen for a short time.
This self-acting pointer
movement can occur when
a slight, steady pressure is applied to the TrackPoint III pointer when
the computer is powered on, when the system is running, or
when readjustment is required
because the temperature has
changed significantly within a short period of time
or the temperature is higher than its operating temperature.
This symptom does not indicate a hardware problem.
No service actions
are necessary if the pointer movement stops in a short period of time.
However, the TrackPoint III will not
stabilize if you apply pressure to it.
If pointer movement occurs, you
can go into Suspend mode, and then resume normal operation.
Resuming or turning the computer on both cause the
TrackPoint III to be calibrated, which may correct the problem.
If you see continual movement of the pointer,
the TrackPoint III is
probably defective.
In rare cases, the top system board can also cause
this problem.
If a click-button problem or
TrackPoint III problem
occurs, perform the following steps:
- Power-off the computer, and then
power it on again.
Press the F1 key any time
while the POST memory count is proceeding.
At the end of the memory test, the Easy-Setup screen screen appears.
- Select an item with the
TrackPoint III.
- Press either the left or right click button.
- Verify that both buttons work correctly.
If either the TrackPoint III or the click button does not work,
perform the following tasks one at a time
to correct the problem:
NOTE:
Do not replace a nondefective FRU.
- Reseat the
three
keyboard cables.
- Replace the keyboard.
- Replace the top system board.
