Disabling a Forgotten Password

The system's software security features include a system password and a setup password, which are discussed in detail in Using the System Setup Program and UEFI Boot Manager. The password jumper enables these password features or disables them and clears any password(s) currently in use.

CAUTION: See "Protecting Against Electrostatic Discharge" in the safety instructions that came with the system.

Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.
Open the system. See Opening and Closing the System.
Remove the jumper plug from the password jumper.

See Figure 6-1 to locate the password jumper (labeled "PWRD_EN") on the system board.

Close the system. See Closing the System.
Place the system upright on a flat, stable surface.
Reattach any peripherals and connect the system to an electrical outlet.
Turn on the system and attached peripherals.

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.

Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.
Open the system. See Opening and Closing the System.
Install the jumper plug on the password jumper.
Close the system. See Closing the System.
Assign a new system and/or setup password.

To assign a new password using the System Setup program, see Assigning a System Password.
