TrackPoint III Checkout

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:
  1.  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.

  2.  Select an item with the  TrackPoint III.
  3.  Press either the left or right click button.
  4.  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.
