Using BIOS passwords
By using the Setup Utility program, you can set passwords to prevent unauthorized access to your computer
and data.
You do not have to set any passwords to use your computer. However, using passwords improves computer
security. If you decide to set any passwords, read the following topics.
Password types
The following types of passwords are available in the Setup Utility program:
• Power-on password
When a power-on password is set, you are prompted to enter a valid password each time the computer is
turned on. The computer cannot be used until the valid password is entered.
• Administrator password
Setting an administrator password deters unauthorized users from changing configuration settings. If you
are responsible for maintaining the configuration settings of several computers, you might want to set an
administrator password.
When an administrator password is set, you are prompted to enter a valid password each time you try to
access the Setup Utility program. The Setup Utility program cannot be accessed until a valid password is
entered.
If both the power-on password and administrator password are set, you can enter either password.
However, you must use your administrator password to change any configuration settings.
• Hard disk password
