              Sorry ....

              I just unlocked today a Dell Latitude 5501 on the same white worked fine.

              Sorry for asking, but you haven't written back your original locked file?

                  Strange and was that exactly the process as shown in this video (fan running at full speed)

                  And it appears **** MANUFACTURING MODE ACTIVE ****

                            You`re off topic, this thread is for the LATITUDE 7420. Anyway, if you don`t know anything about computers i would suggest you take it to a repair shop if you feel you don`t feel confident enough to take the laptop apart. Posting a bios backup is the only way we can help you here.
