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 has been pre-configured. This system partition uses 100 MB 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.
To unlock the encrypted data with a recovery key stored on a USB flash memory device
To unlock the encrypted data with a recovery key stored on a USB flash memory device, your system needs to access the
USB flash memory device when you boot the computer. Follow these steps to configure the boot order in the BIOS setup
screen:
1 Connect a USB flash memory device.
2 Turn on the computer and press the F2 key repeatedly until the VAIO logo disappears.
The BIOS setup screen appears. If the screen does not appear, restart the computer and try again.
3 Press the < or , key to select the Security tab, the M or m key to select Change TPM State, and then the Enter key.
4 Press the M or m key to select Enable and then the Enter key.
