    Lenovo Z580 Bios Unlock

    Hello, I have this Lenovo IdeaPad Z580 (model name: 2151) that has a bios lock. (MB: DALZ3AMB8E0 REV: E)
    What I tried:
    Remove Cmos battery - no help
    Short bios pin (i see this somewhere on the internet) - no help

    On the MB there is two Winbond IC's. (25Q64FV and 25X40BV)
    I read the .bin data from 25Q64FV and try to use Lenovo Autopatcher from this post but I got an error.
    Does anyone know why is there a two Winbond IC's? And how can i remove bios password?
    Here is the data from both IC's

    It's a Phoenix bios, it should show a challenge code after 3 wrong passwords. 25Q64FV is Main bios and 25X40BV is for EC.

        Yep, put the challenge code in https://bios-pw.org/ and you'll get password, restart and write password.

                        Your password may be calculated... Enter three wrong passwords and post the new code.

                                IMPORTANT: Do not type anything until you have received the Unlock Key (password), as Hint Code will change every 3 incorrect passwords. At second incorrect password force computer shutdown and try again.

                                Password: 297934B0

                                    The password is being calculated correctly, Try again to rewrite the original file.
