    Dell Latitude 3520 BIOS Admin PW Required

    Recently purchase a used unit online.
    Only a couple of years old with an 11th gen i5
    Unit works fine with existing OS, but BIOS boot order is inaccessible in without first entering the administrator PW.
    If anyone could be of assistance it would be appreciated.

    Admin Unlock

    The admin password is set on this computer. This operation is not allowed until the correct password is entered.

                    Thank you, my brother, it did not work for me. I think I lost the original program, and unfortunately I did not find it on the sites
