                  @lapfix's BIOS from Post #261 should works fine. See if there any missing component around the BIOS chip, do verification after programming the chip and re-solder the chip again.

                      Re: Dell Latitude 5520 Bios Password unlock

                      Hello geniuses, I have a Dell Latitude 5520 with an admin lock on the bios that I want to remove.

                      Service Tag: H62CNL3

                      In the bios the Admin Unlock says H62CNL3-8FC8

                      Please help me unlock this and possibly remove the password. Thank you

                          Ok, how do I do such a thing?

                          I'll be honest, I'm nowhere near as smart as you guys. Could you please direct me to something I can read that will tell me how to dump my bios file

                            I've done some research. Am I correct in the assumption that I would need a CH341a programmer in order to dump the bios and flash it again?

                              Yes, you are right.

                                            Dell Latitude 7420 BIOS Unlock Gone Wrong
                                            by Jeff'sTech
                                            Hello 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...

                                            Dell Latitude 5400 Chromebook UEFI bios
                                            by jhanra
                                            Hi there masters, recently i got a dell 5400 chromebook and wanted to install windows, i searched the internet and i found out other people also wanting a UEFI bios for this model, i searched there is a R/W legacy, but there are bugs like keyboard/trackpad not working, and hard to install.

                                            so i decided to try to port one, this bios is based on dell 5400 windows version, i am testing this bios for a week now an found only a little to no bug at all in windows 10, or only a minor issue
                                            in windows 11 sound driver compatibility, but overall its ok, for me i can deal with it, 😅😅😅...
