Using BitLocker Drive Encryption with the TPM
BitLocker Drive Encryption is a data encryption feature that is available on models with Windows Vista Ultimate. Enabling
BitLocker Drive Encryption in conjunction with the TPM encrypts all data on the built-in storage device.
For detailed information on how to use and configure BitLocker Drive Encryption, see Windows Help and Support.
See the specifications to find out about the configuration of your computer.
Notes on using BitLocker Drive Encryption
❑ Be sure to initialize the TPM with the Infineon TPM Professional Package before enabling BitLocker Drive Encryption.
If you enable it without initializing the TPM, a TPM owner password is not generated, so you will not be able to configure
the Infineon TPM Professional Package.
❑ The Infineon TPM Professional Package does not make a backup copy of a file (recovery password) for BitLocker
Drive Encryption.
❑ An additional BitLocker system partition (S drive) has been pre-configured. This system partition uses 1.5 GB of your total
built-in storage device volume.
❑ You must enable the TPM in the BIOS setup screen in order to turn on BitLocker Drive Encryption.
❑ Do not encrypt data on a storage device (such as a USB flash memory device) on which a recovery key is stored using
BitLocker Drive Encryption.
