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.
Problem:
The mouse buttons do not work.
Solution:
→ If your ThinkPad computer has the TrackPoint only, this problem
may occur.
Change the mouse driver to Standard PS/2 Port Mouse, and then
reinstall PS/2 TrackPoint. Drivers are provided in the
C:\IBMTOOLS\DRIVERS or C:\SWTOOLS\DRIVERS directory on
your hard disk drive. If your hard disk drive does not contain device
drivers, refer to the ThinkPad Web site. For access to this Web site,
