System and Setup Password Features
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 ). 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 .
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.
TPM Security
(Off default) Sets the reporting of the Trusted Platform Module (TPM) in the system.
When set to Off (default), presence of the TPM is not reported to the operating system.
When set to On with Pre-boot Measurements, the system reports the TPM to the operating system and stores the pre-boot
measurements (compliant with Trusted Computing Group standards) to the TPM during POST.
When set to On without Pre-boot Measurements, the system reports the TPM to the operating system and bypasses pre-boot
measurements.
TPM Activation Changes the operational state of the TPM.
When set to Activate, the TPM is enabled and activated at default settings.
When set to Deactivate, the TPM is disabled and deactivated.
The No Change state initiates no action. The operational state of the TPM remains unchanged (all user settings for the TPM are
preserved).
NOTE: This field is read-only when TPM Security is set to Off.
TPM Clear
(No default)
NOTICE: Clearing the TPM will cause loss of all encryption keys in the TPM. This will prevent booting to the operating system and result in
loss of data if the encryption keys cannot be restored. Be sure to back up the TPM keys prior to enabling this option.
When set to Yes, all the contents of the TPM are cleared.
NOTE: This field is read-only when TPM Security is set to Off.
Power Button
(Enabled default) 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.
NOTE: You can still turn on the system by using the power button, even if the Power Button option is set to Disabled.
NMI Button
(Disabled
default)
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.
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.
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.
