          Hi again ,
          I assume those digits that flash up on the screen at boot is the service tag?
          I managed to capture it but when I enter what I am pretty sure it is I get invalid service tag entered"
          any ideas?

                    1st boot, press F2, write service tag, disable Absolute, save (Apply changes), restart. 2nd boot press Alt+F to exit manufacturing mode. Let it run for 2minutes, it will restart several times with no display.

                                  Is that your Original BIOS?
                                  What is the device Model Number, Service Tag and Motherboard Number?

                                      Here is your New BIOS, try it and let me know.

                                      If the device works on this file, go to BIOS Menu and insert your Service Tag, after that you can press ALT+F to exit Manufacturing Mode.

                                          If the device works on this file, go to BIOS Menu and insert your Service Tag, after that you can press ALT+F to exit Manufacturing Mode.

                                            3 amber 3 white blinks. Dell website sais it's problem "bios recovery" and suggested solution "recovery image not found"

                                            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, 😅😅😅...
