Security Power-On
Authentication overlaps
the BIOS Password during
boot sequence.
The BIOS asks for both
the old and new
passwords through
Computer Setup after the
Owner password is
changed.

Details
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.
The BIOS asks for both the old and new
passwords through Computer Setup
after the Owner password is changed in
Embedded Security Windows software.
Solution
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.
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.
