With this setting, the TrackPoint is disabled automatically if a mouse is connected to the external-input-device connector if any of the following is true: ­ The system is starting. ­ The system is resuming from suspend mode. ­ Your computer is attached to the ThinkPad Port Replicator with Advanced EtherJet Feature. If no external mouse is connected, the TrackPoint remains enabled. A mouse that is compatible with the IBM PS/2 Miniature Mouse can work simultaneously with the TrackPoint if the TrackPoint is set to Enable. To enable the TrackPoint, do as follows: 1 2 3 Start the ThinkPad Configuration program. Click the TrackPoint ( ) button. Click Enable for the TrackPoint. Copyright IBM Corp. 1999 1 Note: If you are using a mouse connected to the serial connector or the USB connector, you should not use the TrackPoint at the same time.
