Precautions on Using the TPM
❑ Although your computer is provided with the TPM security functions, these functions do not ensure complete protection
of your data and hardware. Sony assumes no liability 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. Be sure to write down the
passwords and keep them safe and private from other people.
❑ Be sure to make backup copies of the latest emergency recovery archive file, emergency recovery token file, password
reset token file, and personal secret file and keep them safe and private from other people before sending your computer
for repair. The data stored in the TPM that is embedded on the motherboard may be lost or corrupted during the course
of repair.
❑ During the course of repair, the TPM will also be replaced if the motherboard needs replacement. In such a case, use the
backup copies of the emergency recovery archive file, emergency recovery token file, password reset token file, and
personal secret file to restore the TPM configuration.
❑ Be sure to make a backup copy of the data stored on the built-in storage device before sending your computer for repair.
The built-in storage device 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 device using the backup copies of the emergency recovery archive file, emergency recovery
token file, password reset token file, and personal secret file.
❑ Make sure you set up the automatic backup operations after completing the TPM initialization wizard. If the window
containing the Run automatic backup now check box is displayed after the setup, select the check box and update the
backup files. The restore process using the backup files may fail if you do not set up the automatic backup operations.
❑ The maintenance and management of TPM-protected data must be carried out at your own risk. Sony assumes no liability
for any defects arising out of your data maintenance and management.
