Using the System Setup Program

TPM Clear
(No default)
NOTICE:
Clearing the TPM will cause loss of all
encryption keys in the TPM. This option will prevent
booting to the operating system and will 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. 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.
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.
