1Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.

2Open the system. See "Opening and Closing the System" on page 65.

3Move the password jumper to pins 2-4 to clear the password.

See Figure 6-1 to locate the password jumper on the system board.

4Close the system.

5Reconnect your system and peripherals to their electrical outlets, and turn on the system.

The existing passwords are not disabled (erased) until the system boots with the password jumper plug removed. However, before you assign a new system and/or setup password, you must install the jumper plug.

NOTE: If you assign a new system and/or setup password with the jumper plug still removed, the system disables the new password(s) the next time it boots.

6Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.

7Open the system. See "Opening and Closing the System" on page 65.

8Move the password jumper to pins 4-6 to restore the password function.

9Close the system.

10Reconnect your system and peripherals to their electrical outlets, and turn on the system.

11Assign a new system and/or setup password.

To assign a new password using the System Setup program, see "Assigning a System Password" on page 55.
