Description
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.
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.
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.

restored. If set to Last, the system returns to the last

restored. Off allows the system to remain off after power
is restored.

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