        You said your bios has a password which means bios file in your bios chip is fine, but the file you posted back is corrupt, so the problem is your programmer, which model programmer do you use?

          neo programmer. you may be right before i looked deeper into re programming chips i made a mistake and took a bois backup from a clip. I now solder directly onto the board to reprogram. so i don't have a valid bios back up does that mean this unit is scrapped

              Not sure.If your bios reading has failed, who can guarantee that the bios writing is successful? solve your bios reading problem or you will make things more difficult.

                  Does your device include one or two bios chips?

                      Re: Dell Latitude 5400 Bios password

                      So without a bios backup is it not possible to restore the chip info back to factory?

                        Re: Dell Latitude 5400 Bios password

                        Hi, I am hoping someone can help me to disable Absolute in this bios backup.
                        I managed to permanently activate it due to the confusing wording in the bios GUI.

                        Thanks
