Trusted Platform Module TPM
To use the TPM, you must activate the TPM in the BIOS Setup before the software
is installed. The condition for this is that you have assigned at least the supervisor
password (see "Security functions", Page
Instructions for how to call up and use the BIOS Setup Utility can be found in
section "Settings in BIOS Setup Utility", Page

Enabling TPM

• Requirement: You have set a supervisor password, see
► Call up the BIOS Setup and select the Security menu.
► Mark the TPM (Security Chip) Setting field and press the Enter key
► Select the "Security Chip" "Enabled" entry to activate the TPM
Once you have activated the TPM through a reboot, the Clear Security Chip menu option appears.
With Clear Security Chip, you can delete the owner in the TPM, if the TPM has already
been used. With Enabled, all secret keys generated by applications (e.g. SRK - Storage
Root Keys, AIK - Attestation Identity Keys, etc.) are deleted.
Please note that you will then no longer be able to access the data you have
encrypted with the keys based on that holder.

► Press the Enter key and select Yes.
The notebook will restart, and TPM will be enabled after the reboot.
