The pointer does not
move after the computer
awakens from one of the
power management
modes. Make sure you followed the instructions in the online book correctly when you
installed Windows with the Advanced Power Management (APM) option.
All or some keys on the
keyboard do not work. If the problem occurred immediately after the computer returned from
suspend mode, enter the power-on password if it is set.
If an external keyboard is connected, the numeric keypad on your computer
will not work. This is not a defect.
If an external numeric keypad or a mouse is connected:
1. Turn off the computer.
2. Remove the external numeric keypad or the mouse.
3. Turn on the computer and try using the keyboard again.
If the keyboard problem is resolved, check the connection of the external
numeric keypad, external keyboard, or mouse.
If you still have a problem, have the computer serviced.
The pointer drifts when
the computer is turned on
or after it resumes normal
operation. The pointer may drift when you are not using the TrackPoint III during normal
operation. This is a normal characteristic of the TrackPoint III and is not a
defect. Pointer drifting may occur for several seconds under the following
conditions:
When the computer is turned on.
When the computer resumes normal operation.
When the TrackPoint III is pressed for a long time.
When the temperature changes.
The mouse or pointing
device does not work. Make sure that the mouse or pointing-device cable is securely connected to
the computer.
Try using the TrackPoint III. If the TrackPoint III works, the error might be
due to the mouse.
If your mouse is incompatible with the IBM PS/2 mouse, disable the
TrackPoint III using the ThinkPad Configuration program.
Note: See the manual supplied with the mouse for more information.
The mouse buttons don't
work. Change the mouse driver to Standard PS/2 Port Mouse, and then change to
PS/2 TrackPoint III.
A number appears when
you type a letter. The numeric lock function is on. To disable it, press and hold Shift; then press
NumLk.
