BIOS administrator password
The Computer Setup BIOS 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 and to make changes using Computer Setup.
Note the following characteristics of the BIOS administrator password:
● It is not interchangeable with a Windows administrator password, although both passwords can
be identical.
● It is not displayed as it is set, entered, changed, or deleted.
● It must be set and entered with the same keys. For example, a BIOS administrator password set
with keyboard number keys will not be recognized if you enter it thereafter with embedded
numeric keypad number keys.
● It can include any combination of up to 32 letters and numbers and is not case sensitive unless
mandated by the administrator.
