Disabling a Forgotten Password
NOTE: To perform this procedure, you must connect a keyboard, mouse, and monitor
to your system.
The system's software security features include a system password and a setup
password, which are discussed in detail in Chapter 3, “Using the System Setup Pro-
gram,” in the
User's Guide . A password jumper on the system board enables these
password features or disables them and clears any password(s) currently in use.
NOTICE: Dell recommends that the system password be left in the Not
Enabled (default) setting. When operating your system in the headless
configuration, you will not be able to input a system password in order to
reboot the system.
To disable a forgotten system password or setup password, perform the following
steps.
NOTICE: See “Protecting Against Electrostatic Discharge” in the safety
instructions at the front of this guide.
1. Remove the right-side system cover.
2. Refer to Figure A-1 for the location of the password jumper (labeled “PASSWD”)
on the system board.
3. Remove the jumper plug from the PASSWD jumper.
