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