How can I do this? The PC is currently locked with a BIOS administrator password, and the Windows password is also forgotten. I want to recover or remove the BIOS password, but I don’t have any external tools or hardware. The laptop is a Dell Latitude 5520Comment

The bios chip must be unsoldered from the board before writing or reading..
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..
you need an SPI programmer...here is a video for example..https://www.youtube.com/watch?v=DWWi...nnel=ThisIsHow

I do notice you usually send a ".bin" file back? do I run that or?? cuz it wont let me update the bios? sorry, I am an IT guy 25+ years but this has been a bit disturbing for me as usually i can "defeat" this stuff. Thanks!! and cudo's for this website/blog/forum

You should only run your own .bin file.
You need a programmer, there are many brands, but the cheapest is CH341A (cheapest but not the best).

Good evening. I was finally able to get the bios chip from this soldered to some wires and dump the bios. Are you able to help me unlock and clean it? I hope it dumped right.
Thank you for your help.

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... -
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, 😅😅😅... -
