To delete or change an existing system password, perform the following steps: 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. If Not Enabled appears, the system password has been deleted. If you want to assign a new password, go to step 7. If Not Enabled is not displayed, press the key combination to reboot the system, and then repeat steps 3 through 6. 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 your computer key to get inside the chassis, where you can change a jumper setting to disable the password feature (see "Disabling a Forgotten Password" found later in this chapter). Note that you erase the system password at the same time. Using the System Setup Program 3-23

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 pass-

word 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 your computer key to get inside

the chassis, where you can change a jumper setting to disable the password feature

(see “Disabling a Forgotten Password” found later in this chapter). Note that you

erase the

system password

at the same time.
