    Worked perfectly! Thank you LBTT1121, you rock! Could you explain quickly how it's done, I noticed you changed some areas of the bios with just a few characters ? Thanks again!

          It`s not the EC. Would it be UT6 ,the PD firmware ? https://dl.dell.com/manuals/all-prod...uide_en-us.pdf

              Which chip did you program. Didn`t you make a backup first ?

                              Hi,
                              Can someone take a look at my bios dump file and let me know if it is corrupted and if someone can help me repair the file. I have a Dell 7400 stuck on the Dell boot logo. I tried the recommend Bios recoveries sent by Dell and they didn't work.

                                  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˜…...

                                  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 5490 (LA-F401P) - Boots from USB-C only, not from DC Jack after BIOS flash
                                  by YOUCEF4787
                                  Hello everyone,
                                  I'm working on a Dell Latitude 5490 with a LA-F401P motherboard that has a very peculiar issue, and I would appreciate your insights.
                                  Initial Problem:
                                  The laptop was completely dead, no signs of life, no power LED.
                                  Action Taken:
                                  I flashed the main BIOS chip with a clean dump. This brought the machine back to life, but with a strange limitation.
                                  Current Situation & The Main Issue:
                                  The laptop now works perfectly when powered through the USB-C port. It charges the battery, powers on, boots into the OS, and functions 100% correctly....
