System and Setup Password Features
The system is shipped without the system password feature enabled. If system security is a concern, operate the 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 ." If you forget the
password, you cannot operate the 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. See "
Disabling a Forgotten Password ."
Using the System Password
After a system password is assigned, only those who know the password have full use of the system. When the System Password option is set to Enabled,
the system prompts you for the system password after the system starts.
Assigning a System Password
Before you assign a system password, enter the System Setup program and check the System Password option.
When a system password is assigned, the setting shown for the System Password option is Enabled. If the setting shown for the Password Status is
Unlocked, you can change the system password. If the Password Status option is Locked, you cannot change the system password. When the system
password feature is disabled by a jumper setting, the system password is Disabled, and you cannot change or enter a new system password.
When a system password is not assigned and the password jumper on the system board is in the enabled (default) position, the setting shown for the
System Password option is Not Enabled and the Password Status field is Unlocked. To assign a system password:
1. Verify that the Password Status option is set to Unlocked.
2. Highlight the System Password option and press <Enter>.
3. Type your new system password.
You can use up to 32 characters in your password.
As you press each character key (or the spacebar for a blank space), a placeholder appears in the field.
The password assignment is not case-sensitive. However, certain key combinations are not valid. If you enter one of these combinations, the system
beeps. To erase a character when entering your password, press <Backspace> or the left-arrow key.
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> and then change the password
using the System Password option.
Extended
Security When a system password is entered, setting the Extended Security option to Enabled locks all keys on the keyboard during BIOS POST,
except for the <F2> key. Pressing the <F2> key during BIOS POST displays a password prompt that allows 20 seconds for a valid entry before
continuing to boot the operating system.
Power
Button Turns system's power off and on.
l 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.
l 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.
NMI Button 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.
Sets the NMI feature On or Off.
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.
NOTE: To escape from the field without assigning a system password, press <Enter> to move to another field, or press <Esc> at any time prior to
completing step 5.
