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.
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 are shipped with your product.
