Hardware Maintenance Manual

Using passwords

By using the Setup Utility program, you can set passwords to prevent

unauthorized persons from gaining access to your computer. See Starting

the Setup Utility program. The following types of passwords are available:

• AdministratorPassword

• Power-OnPassword

You do not have to set any password to use your computer. However, if

you decide to set any password, read the following sections.

Password considerations

A password can be any combination of up to 16 characters (a-z and 0-9)

and semicolon (;). For security reason, it is a good idea to use a strong

password that cannot be easily compromised. We suggest the password

should adhere to the following rules:

• Musthaveatleastsevencharactersinlength

• Containatleastonealphabeticcharacterandonenumericcharacter

• SetupUtilityprogrampasswordarenotcasesensitive

• Notbeyournameoryourusername

• Notbeacommonwordoracommonname

• Besignicantlydierentfromyourpreviouspassword

Administrator password

When an Administrator Password is set, it deters unauthorized persons

from changing conﬁguration settings. If you are responsible for

maintaining the settings of several computers, you might want to set an

Administrator Password.

After you set an Administrator Password, a password prompt is displayed

each time you try to access the Setup Utility program.

If both the Administrator and Power-On Password are set, you can type

either password. However, to change any conﬁguration settings, you must

use your Administrator password.

Setting, changing, and deleting Administrator password

To set, change, or delete Administrator password, do the following:

1 2 ... 13 14 15 16 17 18 19 20 21 22 23 ... 52 53
