If the external mouse is connected, the TrackPoint does not work. In this case, please detach the external mouse to check the TrackPoint.
If this does not correct the TrackPoint problem, continue with the following.
After you use the TrackPoint, the pointer drifts on the screen for a short time. This self-acting pointer movement can occur when a slight, steady pressure is applied to the TrackPoint pointer.
This symptom is not a hardware problem. No service actions are necessary if the pointer movement stops ina short period of time.
If a click button problem or pointing stick problem occurs, do the following:
For TP 390E - (2626)
For TP 390/i Series 1700 - (2626, 2627)
If either the pointing stick or the click button does not work, do the following actions one a time to correct the problem.
Do not replace a non-defective FRU.
