Option TPM Security (Off default) TPM Activation (No Change default) TPM Clear (No default) Power Button (Enabled default) 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.
