Disabling a forgotten password
The system's software security features include a system password and a setup password. The password jumper enables these
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 are shipped with your product.
1. Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.
2. Remove the system cover.
3. Move the jumper on the system board jumper from pins 4 and 6 to pins 2 and 4.
4. Install the system cover.
The existing passwords are not disabled (erased) until the system boots with the jumper on pins 2 and 4. However, before
you assign a new system and/or setup password, you must move the jumper back to pins 4 and 6.
