1st boot, press F2, write service tag, disable Absolute, save, restart. 2nd boot press Alt+F to exit manufacturing mode.
Good luck.Attached Filesif you find these attachements useful please consider making a small donation to the site

I am not sure what happened. I reflashed the bios chip and computer is not switching to 20V. I checked the issue and PL201 coil (part of PU200) is measuring only 20 ohms which indicates a short to me. I will address this first, then report whether the password is gone.Comment

Ok, I reflashed the bios. On 1st boot computer fan runs at full spead. On 2nd boot the keyboard backlight comes on along with the charging light. Then, the whole thing turns off and repeats the cycle.
I soldered the original bin and the computer boots with the password. Can you rework your bin file for me to try again?
Thanks.Comment

I tried many bin files. The one that actually worked is located in post # 169:

Yes. I reflashed the bios chip with the original content and the computer booted with the admin password again. I then located this particular bios file, had the bios chip reflashed and the computer booted without the password. I just had to update the service tag as it was empty per instructions.
No worries. Thanks for your assistance.Comment

by Jeff'sTechHello 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 Akhlz001Hi,
Could someone help trying to unlock this BIOS, seems that Dell have changed the layout of new Dell Pro 8FC8 bioses from checking HXD - 4000 bits do not need changing, only 2000. However after FF the section starting from '01000' upto 2000 bits and then soldering the chip back it seems that the microchip on the motherboard is recovering the bios back to original settings after first boot. Has anyone found a way to crack this extra layer of security Dell have implemented? Seems both HP and Dell have upped bios security to match Lenovo by implementing extra measures on a separate...-
