The cursor drifts when
the computer is turned
on or after it resumes
normal operation.
The cursor might drift when you are not using the TrackPoint during normal opera-
tion. This is a normal characteristic of the TrackPoint and is not a defect. Cursor
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.
The mouse or pointing
device does not work.
Make sure that the pointing device 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.
Disable the TrackPoint using the ThinkPad Configuration program if you use
an external mouse.
Note: See the manual supplied with the mouse for more information.
