Password considerations
A password can be any combination of up to 64 alphabetic and numeric characters.
For security reasons, it is recommended to use a strong password that cannot be
easily compromised. To set a strong password, use the following guidelines:
v
Have at least eight characters in length
v
Contain at least one alphabetic character and one numeric character
v
Setup Utility program and hard disk drive passwords are not case sensitive
v Not be your name or your user name
v
Not be a common word or a common name
v
Be significantly different from your previous passwords
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
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 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 configuration 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 the system is turned on.
Setting, changing, and deleting a password
To set, change, or delete a password, do the following:
1. Start the Setup Utility program. See “Starting the Setup Utility program” on
page 49.
2. From the Setup Utility program main menu, select Security .
3. Depending on the password type, select Set Power-On Password , Set
Administrator Password , or Hard Disk Security → Hard Disk Password .
4. Follow the instructions on the right side of the screen to set, change, or delete a
password.
Note: A password can be any combination of up to 64 alphabetic and numeric
characters. For more information, see “Password considerations.”
