v Setup Utility program passwords are not case sensitive
v Not be your name or your user name
v Not be a common word or a common name
v Be significantly different from your previous passwords

Power-On Password

When a Power-On Password is set, the user is prompted to type a valid password
each time the computer is turned on. The computer cannot be used until a valid
password is typed in. For more information about how to set a password, see

"Setting, changing, or deleting a password."

either password. However, to change any configuration settings, you must use
your Administrator Password.
