TrackPoint Checkout (WP z50 - 2608)

TrackPoint Checkout

The TrackPoint adjusts the pointer sensor automatically.
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.
You must readjust it if 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 a pointing stick problem occurs, do the following:.

1.  Go to the diagnostic menu (see 'Running the Diagnostics Test').
2.  Select TrackPoint and run the diagnostics tests.
3.  Verify that the item is selected.
4.  Move to another item with the pointing stick.
5.  Press the pointing stick (press-to-select) and verify that the item is selected.
6.  Verify that both buttons work correctly.

If the click buttons do not work, replace the mainboard.
If the pointing stick does not work, do the following actions one at a time to correct the problem.
Do not replace a nondefective FRU.

•  Reseat the TrackPoint cable.
•  Replace the keyboard.
•  Replace the main board.
