Security
Although you can use the same text for various passwords,
HP passwords and Windows passwords function independently.
Even if you plan to use the same text for an HP password and a
Windows password, you must set the HP password in the Setup
utility and the Windows password in your operating system.
✎
Although their names are similar, an HP administrator
password and a Windows administrator password have
different functions. For example, a Windows administrator
password cannot be used to access the Setup utility, and an
HP administrator password cannot provide administrator-level
access to your notebook contents. You can, however, use the
same text for both passwords.
