you to assign and verify a new system password.

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.

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.

change the system password using the System Password option and cannot be
disabled at system start-up by pressing <Ctrl><Enter>.

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>
and then change the password using the System Password option.

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.

Button option is set to Disabled.

personnel or by the operating system's documentation. Pressing this button
