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.
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.
