TPM Activation Changes the operational state of the TPM.
When set to Activate, the TPM is enabled and activated at
default settings.
When set to Deactivate, the TPM is disabled and
deactivated.
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.
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)
Enables or disables the power off function of the power
button. When enabled, the power button powers off the
system as follows:
• If the system is running an ACPI-compliant operating
system, the system performs 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.
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.
