      Hello!

      My machine is in manufacturing mode. I enter the service tag, but it does not record it. Alt+f does not exit manufacturing mode. The service tag field is empty every time it is switched on!โ€‹

        Since I looked at the file W25Q256JV@WSON8_unlocked.bin you made a mistake with the offset address.
        00048900 = 2400 FCAA 5900 0000 0000 00FF 35B2 2AA6
        00048900 = 2400 FCAA 0000 0000 0000 00FF 35B2 2AA6
        Instead of FCAA 59 you changed FCAA 59 to FCAA 00.
        You changed the 59 to 00 that would explain your problem.โ€‹

                    Only flash this file. In the first boot , you have to go into bios setting for disable all the security options , avoid activate " Computrace " and " Absolute " features.
                    can you help me fix my bios. now my laptop doesn't show the screen the machine turns on for 30 seconds and turns off again restarts again

                                        Hi guys, please, can someone help me unlock this bios? It's from a Dell Latitude 7400, service tag CZB1733.
                                        Many thanks.

                                          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

                                          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˜…...

                                          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...

                                          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...
