    do not use the clip, you may have errors..if you do not have anything to unsolder it with,
    solder wires between the programmer and the bios chip..

    here is a video for example..https://www.youtube.com/watch?v=DWWi...nnel=ThisIsHow
    Thats exactly what i tryed to avoid. my solder-skills are really not good. i´d love to use the clip.

                  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"
                  (from here https://www.dell.com/support/manuals...e7a&lang=en-us)

                  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, 😅😅😅...
