CAUTION!

9.3.2.1 Preliminary steps
Before removing the TPM board, perform the following steps:
Ê
Before removing the TPM board, 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,
see the Microsoft Knowledge Base.
Fujitsu service partners will find additional information (also available
in Japanese) on the Fujitsu Extranet web pages.
