TPM Clear
(No default)

 

CAUTION: 

Clearing the TPM will lose all encryption 

keys in the TPM. This option prevents booting to the 
operating system and results in data loss if the 
encryption keys cannot be restored. Back up the TPM 
keys prior to enabling this option.

When set to Yes, all TPM contents are cleared.

NOTE: 

This field is read-only when 

TPM Security is set to 

Off.

Power Button
(Enabled default)

If Enabled, the power button can turn the system's power 
off and on. On an ACPI-compliant operating system, the 
system performs an orderly shutdown before power is 
turned off.

When Disabled, the button can only turn on system 
power.

NMI Button
(Disabled default)

 

CAUTION: 

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.

Enables or disables the NMI feature.

AC Power Recovery
(Last default)

Determines how the system reacts when power is 
restored. If set to Last, the system returns to the last 
power state. On turns on the system after power is 
restored. Off allows the system to remain off after power 
is restored.

AC Power Recovery Delay Determines when the system restarts after power is 

restored. Options are Immediate, Random (a random 
value of 30 to 240 seconds), or a user-defined value of 30 
to 240 seconds.
