                hi all,

                I have an issue with one 7400 laptop. I've read the chip properly and then I forgot to save it. I've try some bin files from here but laptop doesnt turn on.
                what would be the solution for this issue?

                Chip is a G25B256D

                Thanks

                                          I have an issue with one 7400 laptop. I've read the chip properly and then I forgot to save it. I've try some bin files from here but laptop doesnt turn on.
                                          what would be the solution for this issue?

                                          Chip is a G25B256D

                                          Thanks
                                          managed to measure some voltages on the motherboard and it seems BIOS IC is not getting the 3V.
                                          I dont see anything broken/burned around Bios Chip and I dont the understand why there is a voltage issue on the motherboard now.

                                          Could have been because I've wrote the wrong bin file?

                                            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, 😅😅😅...

                                            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...

                                            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...
