The number of unsuccessful attempts made to enter the correct system password can alert you to an unauthorized person attempting to use your system. Even after your system is turned off and on, the previous message is displayed each time an incorrect or incomplete system password is entered. NOTE: You can use the Password Status category in conjunction with System Password and Setup Password to further protect your system from unauthorized changes. For more information, see "Password Status" found earlier in this chapter. Deleting or Changing an Existing System Password To delete or change an existing system password, perform the following steps: 1. Enter the System Setup program and verify that the Password Status category is set to Unlocked. Enter the System Setup program by pressing the key combination. Press the key combination to move to Page 2 of the System Setup screens. For instructions on changing the setting for Password Status, see "Password Status" found earlier in this chapter. 2. Reboot your system to force it to prompt you for a system password. 3. When prompted, type in the system password. 4. Press the key combination to disable the existing system password, instead of pressing to continue with the normal operation of your system. 5. Confirm that Not Enabled is displayed for the System Password category of the System Setup program. If Not Enabled appears in the System Password category, the system password has been deleted. If you want to assign a new password, continue to step 6. If Not Enabled is not displayed for the System Password category, press the key combination to reboot the system, and then repeat steps 3 through 5. 6. To assign a new password, follow the procedure in "Assigning a System Password" found earlier in this section. Using the Setup Password Feature Your Dell system is shipped to you without the setup password feature enabled. If system security is a concern, you should operate your system with setup password protection. You can assign a setup password, as described in the next subsection, "Assigning a Setup Password," whenever you use the System Setup program. After a setup password is assigned, only those who know the password have full use of the System Setup program. To change an existing setup password, you must know the setup password (see "Deleting or Changing an Existing Setup Password" found later in this section). If you assign and later forget a setup password, you need to be able to remove the computer cover to change a jumper setting that disables the setup password feature (see "Disabling a Forgotten Password" found later in this chapter). Note that you erase the system password at the same time. Assigning a Setup Password A setup password can be assigned (or changed) only when the Setup Password category is set to Not Enabled. To assign a setup password, highlight the Setup Password category and press the left- or right-arrow key. The system prompts you to enter and verify the password. If a character is illegal for password use, the system emits a beep. NOTES: The setup password can be the same as the system password. If the two passwords are different, the setup password can be used as an alternate system password. However, the system password cannot be used in place of the setup password. After you verify the password, the Setup Password setting changes to Enabled. The next time you enter the System Setup program, the system prompts you for the setup password. 2-14 Dell OptiPlex Gn and Gn+ Low-Profile Systems Reference and Installation Guide
