and the touch pad. If the TrackPoint pointing device 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, ThinkPad Advanced Mini
Dock, or the ThinkPad Essential Port Replicator.
If your mouse is incompatible with the PS/2 mouse, disable the TrackPoint

pointing device using the ThinkPad Configuration Program.

Note: For more information, see the manual supplied with the mouse.

Problem:
The scrolling or magnifying glass function does not work.
Solution:
Check the mouse driver in the Device Manager window, and make sure

that the PS/2 TrackPoint driver is installed.

Standby or hibernation problems
Problem:
The computer enters standby mode unexpectedly.
Solution:
If the processor overheats, the computer automatically enters standby
mode to allow the computer to cool and to protect the processor and other
internal components. Also, check the settings for standby mode, using
Power Manager.
Problem:
The computer enters standby mode immediately after Power-on self-test
(POST) (the standby indicator light turns on).
Solution:
Make sure that:

v The battery is charged.

“Specifications” on page 7.

If these items are correct, have the computer serviced.
