14.5 Replacing the system board
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 270.
The TPM is activated in the system BIOS.
V CAUTION!
– Before replacing the system board, ask the customer whether TPM
functionality is used.
