V CAUTION!
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 will cause to lose all data.
14.4.2.1 Preliminary steps
Before removing the TPM, perform the following steps:
Ê Before removing the TPM, it is necessary to remove BitLocker-protection
from the computer and to decrypt the volume.
Ask the system administrator to turn off BitLocker-protection using the
BitLocker setup wizard available either from the Control Panel or Windows
Explorer:
Ê Open Bitlocker Drive Encryption by clicking the Start button, clicking
Control Panel, clicking Security, and then clicking Bitlocker Drive
Encryption.
I Administrator permission required If you are prompted for an
administrator password or confirmation, type the password or
provide confirmation.
Ê To turn off BitLocker and decrypt the volume, click Turn Off BitLocker, and
then click Decrypt the volume.
I Decrypting the volume may be time-consuming. By decrypting the
volume, all of the information stored on that computer is decrypted.
For further information on how to disable BitLocker drive encryption,
please refer to the Microsoft Knowledge Base.
Fujitsu service partners will find additional information (also available
in Japanese) on the Fujitsu Extranet web pages.
Ê Disable TPM in the system board BIOS. Proceed as follows:
Ê Switch on or restart your server.
Ê As soon as the startup screen appears, press the [F2] function key to
enter the BIOS.
