Hardware and Software Guide 12–7
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 Computer
Setup 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 Computer Setup, and an
HP administrator password cannot provide administrator-level
access to your notebook contents. You can, however, use the
same text for both passwords.
HP Administrator Passwords
The HP administrator password protects the configuration
settings and system identification information in Computer Setup.
After this password is set, it must be entered to access Computer
Setup.
The HP administrator password:
Is not interchangeable with a Windows administrator
password, although both can use the same word or series
of letters, or numbers.
Does not display as it is set, entered, changed, or deleted.
Must be set and entered with the same type of keys. For
example, an HP administrator password set with keyboard
number keys will not be recognized if you enter it with
embedded numeric keypad number keys.
Can include any combination of up to 32 letters and numbers
and is not case sensitive.
