Apple Power Macintosh 5400 series - Manual (Page 88)

The pointer (
8
) doesn’t move when you move the mouse.
One of the following situations is probably the cause:
m The mouse is not connected properly.
Check that the mouse and keyboard cables are connected properly, and
then restart the computer.
m Signals from the mouse are not reaching the computer, either because
the mouse needs cleaning or because there is something wrong with the
mouse.
Clean the mouse according to the instructions in Appendix A of this book.
If you have another mouse or pointing device, try connecting and using it.
(Turn off the computer before connecting it.) If the new device works, there
is probably something wrong with the mouse you replaced.
m Your system has a software problem.
Press x-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 before restarting.
Restart your Macintosh. See “Start Over” in the section “When You Run
Into Trouble” earlier in this chapter for instructions.
Check the startup disk and program you were using when the problem
occurred. Make sure that all programs, desk accessories, and system
extensions you’re using are compatible with the system software. Try
starting up the computer from the Disk Tools disk or the CD-ROM disc that
contains system software. (For instructions on how to start up your
computer from the CD-ROM disc, see “Starting Up From a CD-ROM
Disc” in the section “Initializing a Hard Disk” later in this chapter.) If your
computer starts up normally, there may be an extension conflict.
If the problem recurs, you may need to reinstall system software. See
“Installing or Reinstalling System Software” later in this chapter for
instructions.
If none of these procedures solves the problem, consult the service and
support information that came with your computer for instructions on how to
contact an Apple-authorized service provider or Apple for assistance.
