                                            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...
