              Can anyone help me? I have tried some of the above files and they all run at full fan, hanging on the Dell logo. Below is the bios of the device.

                                Trying to revive this Latitude 5420 with motherboard LA-K491P which got a corrupted BIOS.
                                Not sure if there is an admin password set too, would appreciate if someone could have a look.

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