- Remove the jumper plug from pins 1 and 2.
- Place the jumper plug on pins 2 and 3 and wait approximately 5 seconds.
- Replace the jumper plug on pins 1 and 2.

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.

Christophe Grenier wrote a program that calculates the master BIOS password for Dell Latitudes from the Service Tag number. That program is available here.
If a Latitude cannot be booted to run this program, call Dell Technical Support at (800)624-9896 to get the master password.
Dell Technical Support will request the Service Tag and Express Service Code from the bottom of the Latitude.
If the current user is not the original Latitude owner, Dell will transfer the used Latitude’s registration from the original owner with only the Service Tag and Express Service Code from the tag on the laptop.
