Trusted Platform Module (TPM)
For selected models, the embedded Trusted Platform Module (TPM) provides
your computer with basic security functions. In combination with the TPM,
you can encrypt and decrypt your data to strengthen computer security
against inappropriate access.
TPMs are defined by Trusted Computing Group (TCG) and also called
security chips.
See the online Specifications to see whether your model is equipped with
the TPM.
Precautions on Using the TPM
❑ Although your computer is provided with the latest TPM security
functions, these functions do not assure complete protection of your data
and hardware. Sony Corporation assumes no liabilities for any problems
and damages arising out of your use of the functions.
❑ After you have installed the Infineon TPM Professional Package, you
need to set a few TPM passwords on your computer. Without these
passwords, you will not be able to restore any TPM-protected data. Make
sure to write down the passwords and keep them safe and private from
other people.
❑ Make sure to make backup copies of the latest emergency recovery
archive file and the latest emergency recovery token file and keep them
safe and private from other people before sending your computer for
repair. The data stored in the TPM that are embedded on the
motherboard may be lost or corrupted during the course of repair.
❑ During the course of repair, the TPM may be replaced even if there are
no problems with the modules. In such a case, use the backup copies of
the emergency recovery archive file and the emergency recovery token
file to restore the TPM configuration.
❑ Make sure to make a backup copy of the data stored on the hard disk
before sending your computer for repair. The hard disk may be initialized
and returned after the repair work and, in such a case, you will not be
able to restore the data on the hard disk using the backup copies of the
emergency recovery archive file and the emergency recovery token file.
❑ The maintenance and management of TPM-protected data must be
carried out at your own risk. Sony Corporation assumes no liabilities for
any defects arising out of your data maintenance and management.
