Replacement routines
4.11 Replacing the system board 
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 the 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 48.
The TPM is activated in the system BIOS.
V CAUTION!
– Before replacing the system board, ask your customer if he is using 
the TPM functionality.
– If the customer is using the TPM functionality, advise him that he must 
provide you with the TPM backup copies. For security reasons, the 
TPM must be restored/re-saved by the customer.
If the customer DOES NOT have a backup copy, inform him that 
replacing the system board will cause him to lose all his data.
