Power-On Password
When a Power-On Password is set, you are prompted to type a valid password each time the computer is
turned on. The computer cannot be used until the valid password is typed in.
Administrator Password
Setting an Administrator Password deters unauthorized users from changing conguration settings. If you
are responsible for maintaining the conguration settings of several computers, you might want to set an
Administrator Password.
When an Administrator Password is set, you are prompted to type 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 typed in.
If both the Power-On Password and Administrator Password are set, you can type either password. However,
you must use your Administrator Password to change any conguration settings.
Hard Disk Password
Setting a Hard Disk Password prevents unauthorized access to the data on the hard disk drive. When a
Hard Disk Password is set, you are prompted to type a valid password each time you try to access the
hard disk drive.
