Using TpmSecurity feature
This feature
allows you to control whether the Trusted Platform Module (TPM) in
the system is enabled and visible to the operating system. The TpmSecurity
setting is a master switch for all the rest of the TPM fields. System
restart is required after changing the TpmSecurity setting.
- Enabled — BIOS turns on the TPM during POST, and the TPM can be used by the operating system.
- Disabled — BIOS does not turn on the TPM during POST, and the TPM will be nonfunctional and invisible to the operating system.
NOTE: Disabling
this option does not change any settings that you may have made to
the TPM, nor does it delete or change any information or keys you
may have stored there. It simply turns off the TPM so that it cannot
be used. When you re-enable this option, TPM works exactly as it did
before it was disabled.
TpmActivation: Activates and enables the TPM normal state for TPM use. TPM Activation is a setting which is available when the TpmSecurity is enabled.
- Enabled — Activates the TPM.
- Disabled — Displays the current
activation state of the TPM.NOTE: Disabled is a read-only possible value. TpmActivation can be disabled only from the BIOS setup screen.
Example: To enable TpmSecurity.
Set-Item -Path DellSmbios:\TpmSecurity\TpmSecurity "Enabled" -Password <Plain text password>
NOTE: Restart is required
after changing TpmSecurity setting.
Example: To enable TPM Activation. TPM Activation can be enabled only if the
Tpmsecurity is enabled.
Set-Item -Path DellSmbios:\TpmSecurity\TPMActivation "Enabled" -Password <Plain text password>
NOTE: Admin password must be provided and TpmSecurity should have been
enabled to enable the TpmActivation.
