or metal, can distort the optical light signal and
cause tracking problems. If you wish to operate
your mouse on a reflective surface you should first
cover the surface with a non-reflective object, such
as a book or a sheet of paper.
If you are using a cordless mouse, see the section
below for help with establishing good radio
communication between the mouse and the
receiver.
Q: My floppy drive (FDD) is unable to read my
diskette?
A: First, eject the disk, and then reinsert it before
trying to read it again. If you are still unable to
read the diskette, check that it is a disk drive
problem by inserting and attempting to read
other diskettes. You might have a defective
diskette, or your diskette might need formatting.
If you believe that there is a problem with the
drive, take your computer in for servicing.
Q: My system freezes. How can I restore normal
operation?
A: Sometimes Windows experiences problems that
cause the operating system to "hang". Usually
these problems arise from conflicts with the
application software you are running. Press the
Alt-Ctrl-Del keys simultaneously for on-screen
instructions. If Windows is unable to resolve the
problem, you should press Alt-Ctrl-Del again to
reboot. In extreme cases where the keyboard fails
to respond, you might need to press and hold the
power button to perform a "hard" reboot.
If an application continually causes problems, see
its online help file for advice. You might need to
uninstall and then reinstall the software using the
program's Uninstall utility or, if it does not have
one, by using the Windows Add/Remove Programs
facility. See the Windows online help file for more
information.
