Disabling a Forgotten Password
The password jumper on the system board enables the system password
features or disables them and clears any password(s) currently in use.
CAUTION: Many repairs may only be done by a certified service technician. You
should only perform troubleshooting and simple repairs as authorized in your
product documentation, or as directed by the online or telephone service and
support team. Damage due to servicing that is not authorized by Dell is not covered
by your warranty. Read and follow the safety instructions that came with the
product.
1 Turn off the system and attached peripherals, and disconnect the system
from the electrical outlet.
2 Open the system. See "Opening the System" on page 47.
3 Move the PWRD_EN jumper to the disabled position.
See Figure 6-1 to locate the password jumper on the system board.
4 Close the system. See "Closing the System" on page 47.
5 Reconnect the system to the electrical outlet, 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.
