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.

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