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" on page 35. 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.
1
Turn off the system, including any attached peripherals, and disconnect
the system from the electrical outlet.
2
Open the system. See "Opening and Closing the System" on page 59.
3
Remove the jumper plug from the password jumper.
See Figure 6-1 to locate the password jumper (labeled "PWRD_EN") on
the system board.
4
Close the system. See "Closing the System" on page 60.
5
Place the system upright on a flat, stable surface.
6
Reconnect the system to its electrical outlet and turn the system on,
including any 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.
7
Turn off the system, including any attached peripherals, and disconnect
the system from the electrical outlet.
8
Open the system. See "Opening and Closing the System" on page 59.
9
Install the jumper plug on the password jumper.
10
Close the system. See "Closing the System" on page 60.
11
Assign a new system and/or setup password.
To assign a new password using the System Setup program, see "Assigning
a System Password" on page 49.
