Disabling a forgotten password

The software security features of the system 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.
Prerequisites
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.

2. Remove the system cover.
3. Move the jumper on the system board jumper from pins 4 and 6 to pins 2 and 4.

password(s) the next time it boots.
