Trackpoint Problems - IBM ThinkPad T22 2647 Supplementary Manual

Solving computer problems
Problem: All or some keys on the external keyboard do not work.
Solution: To use an external keyboard, you need to attach the
keyboard/mouse cable or dock the ThinkPad Dock to the computer. Make
sure that:
v The keyboard/mouse cable is correctly connected to the computer.
v The keyboard cable is connected to the correct side of the keyboard/mouse
cable or the ThinkPad Dock.
If these connections are correct, disconnect the keyboard/mouse cable from
the computer and make sure that the keyboard operates properly. If the
built-in keyboard works, there is a problem with either the cable or the
keyboard. Try using a different keyboard/mouse cable or external keyboard.

TrackPoint problems

Problem: The cursor drifts when the computer is turned on or after it resumes
normal operation.
®
Solution: The cursor 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. Cursor drifting might occur for several seconds under the
following conditions:
v When the computer is turned on.
v When the computer resumes normal operation.
v When the TrackPoint is pressed for a long time.
v When the temperature changes.
Problem: The cursor does not work for a while after the settings in the Mouse
Properties window have been changed.
Solution: This is a normal characteristic of the cursor. Wait several seconds
until the cursor returns to the normal state.
Problem: The mouse or pointing device does not work.
Solution: Make sure that the pointing-device cable is enabled in the ThinkPad
Configuration Program.
Make sure that the mouse or pointing-device cable is securely connected to
the computer.
Try using the TrackPoint. If the TrackPoint works, the error might be due to
the mouse.
