            1st boot, press F2, write service tag, disable Absolute, save, restart.
            2nd boot press Alt+F to exit manufacturing mode.
            Good luck.

                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...

                by gizaha
                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 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, ๐Ÿ˜…๐Ÿ˜…๐Ÿ˜…...
