Description
When set to Activate, the TPM is enabled to default
settings. When set to Deactivate, the TPM is disabled.
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.
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.
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.

restored. Options are Immediate, Random (a random
value of 45 to 240 seconds), or a user-defined value of 45
to 240 seconds.

You can enter a value between 45 and 240 seconds. You

This field is active when AC Power Recovery Delay
is set to User Defined.
