        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. And remove CMOS battery.

                      Its not exactly clear what you mean by "clear me" ,do you mean clean the ME firmware.Do you mean the bios isn`t working properly and you want it fixing. Do you mean it has a password,if so then say it has a password.

                                    your file is twice as size and is a merged file of 2 identical dumps. What is your bios chipset? It should be Winbond W25Q256 or GigaDevice GD25x256C, or that new MX77L25650F (id C27519), confirm that is a 256Mb chipset.

                                            Dell latitude 5580, motherboard cdp 80 la-e151p

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

                                            I try plugging charger while pressing ctrl+esc, machine turns on, nothing and after 20 seconds it gives 3 amber 3 white blinks again.

                                            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, 😅😅😅...
