Note on TPM
I
The system board can be equipped with an optional TPM (Trusted
Platform Module). This module enables third party programs to store key
information (e. g. drive encryption using Windows Bitlocker Drive
Encryption).
If the customer is using TPM functionality, the TPM has to be removed
from the defective system board and connected to the new system
board. For a detailed description, see
page
289.
The TPM is activated in the system BIOS.
V
CAUTION!
– Before replacing the system board, ask the customer whether TPM
functionality is used.
– If the customer is using TPM functionality, remove the TPM from the
old system board and install it on the new system board.
Advise your contact persons that they must provide you with all
recovery keys which belong to the system to restore them in the TPM
later.
