Center (page 163).

2 Press the < or , key to select the Security tab, the M or m key to select Change TPM State, and then the Enter key.

3 Press the M or m key to select Enable and then the Enter key.

You can also disable the TPM and clear the TPM configuration in the BIOS setup screen.

Before enabling the TPM, be sure to set the power-on password to protect against unauthorized modification of the TPM configuration.

If the TPM is enabled, it will take longer before the VAIO logo appears due to security checks at computer startup.

You will not be able to access any TPM-protected data if you clear the TPM ownership. Before clearing the TPM configuration, be sure to make backup

copies of the TPM-protected data.
