        You need a programmer. Ex: CH341A

            Programmer only helps you get locked content except bios chip. Then you use this tool : https://www.badcaps.net/forum/troubl...l-8fc8-patcher

              Quick question. Do I still have to use CH341A programmer and install 8FC8 Patcher on 7400 and execute it or I don't need CH341A at all, just use the patcher???

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

                                post motherboard model, post the original contents of the bios chip..etc.

                                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...l=ThisIsHowโ€‹

                                    Thread merged..next time look for a thread with the name and model, motherboard model of the laptop, and post there, if you can't find it, then make a new thread..

                                        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˜…...

                                        Dell Latitude 5430 Bios Password
                                        by anlsmith
                                        I am trying to remove the BIOS password for a Dell Latitude 5430 motherboard LA-L591P. So far I think that I have located the BIOS chip but NeoProgrammer says that is detects 3 chips. I have attached the dump from each one. Are any of these the BIOS file? Service Tag: 1DMC1T3. If nyone knows the exact location of the bios chip as well I would greatly appreciate it...

                                        Dell Latitude E7270 - Requesting BIOS clean/corrupt? service tag CB00KC2

                                        Hi

                                        i have dell latitude E7270 with following symptoms:
                                        - takes long time to restart.
                                        - sometimes powers on and then off
                                        - sometimes while working it just dies,

                                        From googling online bios clean could possible resolve this?

                                        i was able to save bios and was going to try bios clean myself but get an below error when i drop it in ME analyzer.(unsure whether this sometimes occurs or could be due to bad/corrupt bios)

                                        As ME analyzer gave me an error i just decided to write bios with a cleaned bios from E7270 bios post.
                                        I reinstall...

                                        Dell Latitude 5520 - dump bios to obtain password
                                        by iwu
                                        Hello,

                                        I am not experienced in electronics, but I really want to check if my idea is possible.

                                        I have motherboard replaced from Dell Latitude 5520 (11th gen on i5 CPU).
                                        BIOS/UEFI access on that MB/PC is blocked by password which I want to get it know - even if I need some bruteforcing or stupid manual activities.
                                        There was no computrace activated.

                                        I was happy when I saw many posts about removing BIOS password based on .bin file dummps. I wanted to go little further - get to know the password from the dump.

                                        1. I do not know how thebios...
