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 with 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. Drift might last 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 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.
If your mouse is incompatible with the IBM PS/2
®
mouse, disable the
TrackPoint, using the ThinkPad Configuration Program.
Note:
For more information, see the manual supplied with the mouse.
Problem:
The mouse buttons do not work.
Solution:
Change the mouse driver to Standard PS/2 Port Mouse, and then
reinstall IBM PS/2 TrackPoint. Drivers are provided in the

drive does not contain device drivers, refer to the ThinkPad Service &
Support Web site. To access this Web site, open Access ThinkPad by pressing
the ThinkPad button, then click the Service & Support image on the right of
the screen.
