Table 2-7. System Security Screen Options (continued)

Option

Description

 

 

TPM Clear

NOTICE: Clearing the TPM will cause loss of all encryption

(No default)

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

Turns system’s power off and on.

(Enabled default)

• 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.

 

 

NMI Button

NOTICE: Use the NMI button only if directed to do so by

(Disabled default)

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

Determines how the system reacts when power is restored to the

(Last default)

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.
