TrackPoint III Checkout (2600-310/310D/310E/310ED)

TrackPoint III Checkout

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 re-adjustment is required because the temperature has exceeded it's 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')
  2.  Go to the diagnostic Manual Test menu.
  3.  Press F2 in the test items.
  4.  Press the left and right click button.
  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.
