Security Power-On

Authentication overlaps

the BIOS Password during

boot sequence.

Power-On Authentication prompts the

user to log on to the system using the

TPM password, but, if the user presses

F10 to access the BIOS, the user is

granted Read rights access only.

To be able to write to BIOS, the user must type the BIOS

password instead of the TPM password at the Power-

on Authentication window.

The BIOS asks for both

the old and new

passwords through

Computer Setup after the

Owner password is

changed.

The BIOS asks for both the old and new

passwords through Computer Setup

after the Owner password is changed in

Embedded Security Windows software.

This is as designed. This is due to the inability of the

BIOS to communicate with the TPM, after the operating

system is up and running, and to verify the TPM pass

phrase.
