Problem:
The pointer (mouse arrow) freezes on the screen.
Cause 1:
Your mouse and/or keyboard cable may be loose or
disconnected.
Solution:
Press the power button on the front of the computer.
Once your computer is turned off, reconnect the
cable(s). You will lose any unsaved work, but
do not
connect or secure cables while the power is on
; you
could damage your computer.
Cause 2:
Signals from the mouse are not reaching the computer,
either because mouse needs cleaning or because there
is something wrong with the mouse.
Solution:
Clean the mouse according to the instructions in
Appendix A.
Solution:
If you have another mouse or pointing device, try
connecting and using it. (Always turn off the computer
before connecting a mouse or pointing device.) If the
new device works, there is something wrong with the
mouse you replaced.
Tip:
Press Command-Option-Esc to quit the application
program in use when the problem occurred. If this
works, you can save the documents open in other
programs, then restart.
Cause 3:
You may be using a software program or system
extension that is incompatible with the system
software.
Solution:
Make sure that any software you install on your
computer is compatible with the system software.
Solution:
System extensions can be incompatible with your
system software and with each other. To identify
incompatible extensions, use the Extensions Manager
control panel to turn off individual extensions. For
information on using this control panel to manage
system extensions, see the “Setting Options” topic of
Macintosh Guide, available in the Guide menu.
Solution:
If the problem recurs, you may need to reinstall
system software.
If none of these procedures solve the problem, consult the servic
e
and support information that came with your computer for
instructions on how to contact a UMAX Computer service provider.
