Padlock
Your computer is equipped with a padlock loop so that the computer cover cannot
be removed when a padlock is installed.
Password protection
To deter unauthorized use of your computer, you can use the Setup Utility
program to set a password. When you turn on your computer, you are prompted
to type the password. The computer cannot be used until a valid password is
typed in. Refer to Chapter 4, “Using the Setup Utility program,” on page 59 for
more information.
