System and Setup Password Features

NOTICE:
The password features provide a basic level of security for the data on your system. If your data requires
more security, use additional forms of protection, such as data encryption programs.
NOTICE:
Anyone can access the data stored on your system if you leave the system running and unattended
without having a system password assigned or if you leave your system unlocked so that someone can disable the
password by changing a jumper setting.
Your system is shipped to you without the system password feature enabled. If system security is a
concern, operate your system only with system password protection.
To change or delete an existing password, you must know the password (see "Deleting or Changing an
Existing System Password" on page 47). If you forget your password, you cannot operate your system or
change settings in the System Setup program until a trained service technician changes the password
jumper setting to disable the passwords, and erases the existing passwords. This procedure is described in
"Disabling a Forgotten Password" on page 145.
Description
Turns system's power off and on. On an ACPI-compliant operating system, the
system performs an orderly shutdown before power is turned off.
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.
NOTICE:
Use the NMI button only if directed to do so by qualified support
personnel or by the operating system's documentation. Pressing this button
halts the operating system and displays a diagnostic screen.

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.
