Note on TPM
IThe 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 "Trusted Platform Module (TPM)" on page 204.
The TPM is activated in the system BIOS.
VCAUTION!
–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.
If the contact persons DO NOT have a backup copy available, inform them that replacing the TPM board will cause to lose all data.
