System board and components
14.3.2.1 Preliminary steps
I Preliminary steps are not necessary, if a system board has to be replaced
and the TPM is used again.
Before removing the TPM board, 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 more information on how to disable BitLocker drive encryption,
see the Microsoft Knowledge Base.
For more information, see the Fujitsu 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, enter the BIOS setup menu.
Ê Select the Advanced menu.
Ê Select the Trusted Computing submenu.
Ê Set the TPM Support and TPM State settings to Disabled.
Ê Save your changes and exit the BIOS.
I For detailed information on how to access the BIOS and modify
settings, see the corresponding BIOS Setup Utility reference manual.
