(Off default)
TPM Activation
(No Change default)
TPM Clear
(No default)
Power Button
(Enabled default)
Using the System Setup Program and UEFI Boot Manager
Description
Sets the reporting of the Trusted Platform Module
(TPM) in the system.
If Off, the presence of the TPM is not reported to the
operating system.
If On with Pre-boot Measurements, the system reports
the TPM to the operating system and stores the pre-boot
measurements to the TPM during POST.
If On without Pre-boot Measurements, the system
reports the TPM to the operating system and bypasses
pre-boot measurements.
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.
