Using BIOS passwords
By using the Setup Utility program, you can set passwords to prevent unauthorized access to the computer
and data.
You do not have to set any passwords to use the computer. However, using passwords improves computer
security. If you decide to set any passwords, read the following topics.
Setup Utility program password types
The following types of passwords are available:
• 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.
