A change to Setup Password becomes effective immediately (rebooting the system is not required).
Operating Your System With a Setup Password Enabled
When you start system setup, the Setup Password option is highlighted, prompting you to type the password.
If you do not enter the correct password, the system lets you view, but not modify, system setup options.
Deleting or Changing an Existing Setup Password
To change an existing setup password, you must know the setup password.
1. Enter system setup.
2. If you have already assigned a setup password, type it at the prompt.
3. Highlight Setup Password and press the left- or right-arrow key to delete the existing setup password.
The setting changes to Not Enabled.
4. If you want to assign a new setup password, perform the steps in " Assigning a Setup Password ."
Disabling a Forgotten Password
NOTICE: This process erases both the system and setup passwords.
1. Open the computer cover.
2. Remove the jumper plug from the PSWD jumper to disable the password feature.
See " Jumper Settings " to locate the password jumper (labeled "PSWD") on the system board.
3. Close the computer cover.
4. Reconnect your computer and peripherals to an electrical outlet, and then turn them on.
This erases the existing password(s).
5. Enter the system setup program and verify that the password is disabled. Proceed to step 6 if you want to assign a new password.
6. Open the computer cover.
7. Replace the PSWD jumper plug.
8. Close the computer cover and reconnect the computer and peripherals to an electrical outlet and turn them on.
Booting your system with the PSWD jumper installed reenables the password feature. When you enter system setup, both password
options appear as Not Enabled, meaning that the password feature is enabled but that no password is assigned.
9. Assign a new system and/or setup password.
System Settings
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.
NOTE: You can use Password Status in conjunction with Setup Password to protect the
system password from unauthorized changes.
CAUTION: Before you open the computer cover, see " Safety First —For You and Your Computer ."
NOTE: Before you assign a new system and/or setup password, you must replace the PSWD
