Ultranav Problems - Lenovo ThinkPad T60 Series Service And Troubleshooting Manual

Problem
Some or all of the keys on the external PS/2 keyboard do not work.
Solution
→ If you are using the ThinkPad Advanced Dock, the ThinkPad
Advanced Mini Dock, or the ThinkPad Essential Port Replicator, make
sure that the keyboard cable is correctly connected to the keyboard
connector.
If the connection is correct, disconnect the cable and make sure that the
built-in keyboard operates properly. If the built-in keyboard works,
there is a problem with the external keyboard. Try using a different
external keyboard.

UltraNav problems

Problem:
The pointer drifts when the computer is turned on or after it resumes
normal operation.
Solution:
→ The pointer might drift when you are not using the TrackPoint
during normal operation. This is a normal characteristic of the
TrackPoint and is not a defect. Pointer drifting might occur for several
seconds under the following conditions:
– When the computer is turned on.
– When the computer resumes normal operation.
– When the TrackPoint is pressed for a long time.
– When the temperature changes.
Problem:
The mouse or the 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 mouse or the
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
mouse or the pointing device.
Make sure that the cable for the mouse or the pointing device is
securely connected to the ThinkPad Advanced Dock, the ThinkPad
Advanced Mini Dock, or the ThinkPad Essential Port Replicator.
If your mouse is incompatible with the PS/2 mouse, disable the
TrackPoint, using the ThinkPad Configuration Program.
Note: For more information, see the manual supplied with the mouse.
