4-4 Maintaining Your Computer
See your MS-DOS and Windows for Workgroups docu-
mentation for information about backup procedures. Make
backup copies of your program and data files that are on
diskette and on the hard disk.
The standard practice for diskette backup is to copy each
diskette, store the original in a safe place, and use the copy
as your working diskette. You can use the MS-DOS
DISKCOPY command for making copies of your disk-
ettes. See your MS-DOS documentation for information
about using the command.
MOUSE CARE

the mouse ball and tracking mechanism. Periodically,
however, you might need to wipe the mouse ball clean.
Use the following procedure to clean the mouse.

to it.

cover (see the following figure).

the cover.
4.

your palm.
