I'm interested in the same matter. In the documents you advice, there is written "removal of the password": in other words, you HAVE NOT the password, but you want to recover all your data.
We are talking about entering the BIOS, going to the "HDD Password" field and then unregister the password which WE HAVE. If you enter the field (Space or Backspace key), you can only enter a new password, but it seems there is no way to unregister the old. If you enter the field, leave it blank and press "Enter" again, all you get is a "Registered" message. I tried almost every key and combination of keys...useless!
It is very strange it is so difficult to unregister a password. In the "password utility" software you can read easily that the user HDD password can be unregistered using BIOS software, but not the BIOS Config Utility under Windows.
So...does anyone know how to unregister this
damned password?
Thanks.
P.S. I have a Portegè R500 with HDD. It is not the same, but I think the problem could be solved with the same procedure.
