System board and components
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, please refer to section "Replacing the
TPM" on page 313.
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 TPM
backup copies. For security reasons, the TPM must be restored / re-
saved by the customer. After installing a new system board the TPM
must be enabled. You may not clear the TPM data.
