Jumpers and Connectors 179
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 57. 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 82.
3
Move the password jumper to the "disabled" position to clear the password.
See Table 6-1. See
Figure 6-1
to locate the password jumper on the system
board.

Close the system.
5
Reconnect the system to its electrical outlet and turn the system on,

The existing passwords are not disabled (erased) until the system boots
with the password jumper plug in the "disabled" position. However, before
you assign a new system and/or setup password, you must return the
jumper plug to the enabled position.
NOTE: If you assign a new system and/or setup password with the jumper
plug still in the "disabled" position, the system disables the new password(s)
the next time it boots.
