    You shouldn't have done that, you were a bit hasty in that case I'm afraid. You will have to do everything from the beginning because the Service Tag can only be entered in active manufacturing mode. The Service Tag along with the Express Service Code are printed on the factory label, which is usually located on the back cover.

      Friend, enter the bios in the menu on the left, look for where it says maintenance, and enter the service tag that is written on the bottom of the equipment, if you do not have the tag, let me know so I can indicate your stag

          Due to a lack of donations, server free space at a critical level, and possible closure of Bios Requests
          all donations are welcome,
          see the donate button at the bottom of the page,

          Every donation made will go towards server fees and maintenance costs.

                        A very neatly presented question, everything is clear and understandable at first glance.

                          Hello brother
                          can I ask a question ?
                          Where do I learn to remove the password from Bios
                          Or do you use a program to unlock it?

                                I am a member of the forum since 2021, and I benefited a lot from it, It doesn't mean that I didn't post posts, so I don't know.
