I am facing nearly identical issues on a nearly identical HP.
i have used the 'bios hack' instructions from the 'this is your lucky day' post, which worked like a charm [ the windows-key + up and down arrow and on/off button, then F10 slamming]
however, this is all very informative and great educational as i've now learned how to bypass BIOS security, remove fingerprint identification, but i have yet to find the step regarding Mcafee Endpoint Encryption removal.
it simply comes back up every time [password token].
and i have no clue bypassing it/removing it.
did any method find success that i can't find [yet]?
