Solving computer problems

Problem:

The mouse or the pointing device does not work.

Solution:

Make sure that the TrackPoint is enabled in the ThinkPad Configuration Program, and then try using the TrackPoint. If the TrackPoint works, the error might be due to the mouse.

Make sure that the mouse or pointing-device cable is securely connected to the ThinkPad Dock II, the ThinkPad Mini Dock, or the ThinkPad Port Replicator II.

If your mouse is incompatible with the PS/2 mouse, disable the

TrackPoint, using the ThinkPad Configuration Program.
