According to the following website...
Dell Inspiron BIOS Password Recovery

Each Dell Inspiron has a master password that clears the BIOS password. Call Dell Technical Support at (800)624-9896 to get this number.

Dell Technical Support will request the Service Tag and Express Service Code from the bottom of the Inspiron.

If the current user is not the original Inspiron owner, Dell will transfer the used Inspiron's registration from the original owner with only the Service Tag and Express Service Code from the tag on the laptop.

To transfer a used Dell Inspiron's registration, fill out the Transfer of Ownership form on Dell's web site. See... http://www.tech-faq.com/reset-dell-bios-password.html

Only you know the password.

Rollins51,
I believe all Dell uses now is the Service Tag and Express Service Codes. Both of which are found on the bottom of Dell Notebook Computers.
Check out this link for more info for finding your Dell Service Tag and Express Service Codes.

I’m happy to assist further over the phone at https://www.6ya.com/expert/larry_0800578514b4ccdb
