3.4. Dell
Dell laptops store the password in EC. However, some generators exist depending on the code suffix.
See: https://beta.bios-pw.org/ .If the website is offline try: https://web.archive.org/web/*/https://bios-pw.org/
Note: All passwords must be entered with a US QWERTY Keyboard,you can use a USB one.
Note: The 6FF1 suffix has a bug,use your service tag with the 1F5A or BF97 suffix instead,Example: 1234ABC-BF97 .
Note: The list of examples does not include some other suffix codes that do work,such as E7A8 .
Note: If the BF97 suffix does not work try it with the E7A8 suffix instead.
Note: There is no publicly available 8FC8 generator available at the moment.
The CTRL-ENTER-ENTER keystroke after the password only applied to laptops with a suffix (xxxxxxx-8FC8 for example), until Dell also required it in some laptops using System Disable 16-Hex algorithm, on which only the Password+ENTER was needed at first and then in some models you needed the CTRL-ENTER-ENTER to properly delete the system passwords, otherwise the password would remain SET upon the automatic system reboot if just doing Password+ENTER until the proper CTRL-ENTER-ENTER keystroke was performed in certain models.

by Jeff'sTechHello everyone.
I have come here with a rather specific question. I was given a Dell Latitude 7420 laptop with a busted screen, and wanted to see if I could refurbish it into my daily driver. I wanted to experiment and see if a 2-in-1 display would work as the chassis of the laptop and 2-in-1 7420 looked identical. I threw in the display and my hypothesis was correct, however, I was greeted with a locked BIOS and since I didn't know the password, I figured I'd try to unlock it somehow. I bought one of those POGO pin probe things for my CH341A programmer so I could read and make... -

by Akhlz001Hi,
Could someone help trying to unlock this BIOS, seems that Dell have changed the layout of new Dell Pro 8FC8 bioses from checking HXD - 4000 bits do not need changing, only 2000. However after FF the section starting from '01000' upto 2000 bits and then soldering the chip back it seems that the microchip on the motherboard is recovering the bios back to original settings after first boot. Has anyone found a way to crack this extra layer of security Dell have implemented? Seems both HP and Dell have upped bios security to match Lenovo by implementing extra measures on a separate...-
