I followed the Dell website guide to get the service tag. Says it should be labeled EX on the sticker. Here's all the codes from the sticker but I think it's actually the ST one. Could have sworn I saw the bios say 6P13SL3 code followed by 8FC8 or similar.

Good day
Please HELP
I wanted to change serial number on the laptop but then the laptop doesn't display anymore after bios reprogram , I have tried every clean bios from this thread, but the unit complains about corrupt bios (3 amber and 6 white light flash ) and just simply doesn't want to display, I have been trying for 3 days from page 1 until the last page and still no display with every bios file I try.
I eventually gave up and restored the original BIOS file and now there's no power no sign of life. PLEASE HELP.

I am very beginner in programming a chip... the problem i start with is the question, which Manufacturer to choose in CH341A and which name the chip is. its a XMC 25RH256CXIQ PPF83600 01 2128U. Yes, its a Latitude 5520
maybe this thread is not the correct one, but i am desperate. There was the BIOS Pending to install, but i had no Battery, so it couldn´t flash it. Then I received the Battery I purchased and i plugged it on (but maybe not good enough). Then the System booted. No sign of flashing yet, and i plugged the powercord off, cause i wanted to empty the battery before charching cause it was new. But as the battery was not plugged in well, it shut off immediately. Since then, no sign of life. Absolutely dead machine
I hope i can get support here and someone can help me to get that machine to life again. I cannot send a dump because i do not know which kind of chip to choose
I purchased the CH341 programmer and hope to get this problem solvedLast edited by Thoa; 06-27-2025, 12:23 PM.Comment

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

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, 😅😅😅... -
