Caring for your ThinkPad computer
Though your computer is designed to function reliably in normal work
environments, you need to use common sense in handling it. By following
these important tips, you will get the most use and enjoyment out of your
computer.
Important tips:

battery charge level. Extended contact with your body, even through
clothing, could cause discomfort or, eventually, a skin burn.

UltraNav and TrackPoint problems
Problem:
The pointer drifts when the computer is turned on or after it resumes
normal operation.
Solution:
The pointer 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. The pointer drifts 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:
Solution:
The mouse or the pointing device does not work.
Make sure that the TrackPoint is enabled in the ThinkPad Configuration
Program, and then try using the TrackPoint. If the TrackPoint works, the
error might be due to the mouse.
Chapter 3. Solving computer problems 17

Problem:
When you take action to return from standby mode, the computer display
remains blank.
Solution:
Check whether an external monitor was disconnected while the computer
