you to assign and verify a new system password.
NOTE: See "Using the System Password" on page 37 for instructions on assigning a
system password and using or changing an existing system password.
Setup Password Restricts access to the System Setup program in the same way that you restrict
access to your system using the system password feature.
NOTE: See "Using the Setup Password" on page 39 for instructions on assigning a
setup password and using or changing an existing setup password.
Password Status Setting the Setup Password option to Enabled prevents the system password from
being changed or disabled at system start-up.
To lock the system password, assign a setup password in the Setup Password option
and then change the Password Status option to Locked. In this state, you cannot
change the system password using the System Password option and cannot be
disabled at system start-up by pressing <Ctrl><Enter>.
To unlock the system password, enter the setup password in the Setup Password
field and then change the Password Status option to Unlocked. In this state, you
can disable the system password at system start-up by pressing <Ctrl><Enter>

Front-Bezel Chassis
Intrusion
Enables or disables the chassis-intrusion detection feature.
Power Button
Turns system's power off and on.
If you turn off the system using the power button and the system is running an
ACPI-compliant operating system, the system can perform an orderly shutdown
before power is turned off.
If the system is not running an ACPI-compliant operating system, power is turned
off immediately after the power button is pressed.
The button is enabled in the System Setup program. When disabled, the button
can only turn on system power.
NOTE: You can still turn on the system by using the power button, even if the Power
Button option is set to Disabled.
AC Power Recovery
(Last default)
Determines how the system reacts when power is restored to the system. If system
is set to Last, the system returns to the last power state. On turns on the system
after power is restored. When set to Off, the system remains off after power is
restored.
