Problem: The PS/2® Port mouse or the PS/2 pointing device does not work.

Solution: Make sure that the TrackPoint and the touch pad are set to Automatic in the ThinkPad Configuration Program. Then detach the PS/2® Port mouse or the PS/2® pointing device, and try using the TrackPoint and the touch pad. If the TrackPoint and the touch pad work, the error might be due to the PS/2® Port mouse or the PS/2® pointing device.

Note: Some models have the TrackPoint only, without a touch pad and its buttons.

Make sure that the cable for the PS/2® Port mouse or the PS/2® pointing device is securely connected to ThinkPad Port Replicator, Port Replicator II or MiniDock.
