On models with Windows 7 Ultimate or Windows 7 Enterprise, you can use BitLocker to encrypt all the data on the built-in storage device.
Refer to Windows Help and Support for more information on the BitLocker settings and operations.

To unlock the BitLocker-protected drive with a USB flash drive, follow these steps:
Note

  • With the default Sleep mode settings, the computer’s state is saved to the dedicated partition when your VAIO computer enters Sleep mode. You, however, cannot encrypt this partition with Windows BitLocker Drive Encryption or other drive encryption features.
    It is strongly recommended that you first recover the computer with the settings which the dedicated partition is not created with to avoid leaving unencrypted data if you use the drive encryption feature. [Details]
