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>
