Troubleshoot the Hardware
When dealing with problems involving touchpad or track point tracking or responsiveness, it is a good idea to make sure the device is clean, and in the proper operating environment.
To clean the touchpad, wipe it off with a soft cloth, dampened with rubbing alcohol.
If the track point cap is dirty or sticky, replace it.
Touchpads work best in a temperate, dry environment. Any excess of moisture, heat, or cold can result in poor performance. Problems can be caused by factors often overlooked, like dirty or sweaty hands.
If the notebook has both devices, check the responsiveness with the other device.
If both are failing in the same manner, it is mostly a software issue.
