Padlock
Your computer is equipped with a padlock loop so that the computer cover cannot
be removed when a padlock is installed.

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 61 for
more information.
