    Hi.
    I have programmed this file on my zbook 15 g4 in order to remove the password. But I get blank screen with this file. So, your file did not work for me.
    Can you please remove the password from my file.
    Thanks for your support

    Thanks for quick reply. I programmed the file that you sent me but unfortunately the password is still there! :(
    When I powered the laptop on after I programmed the file I got a message that "BIOS has recovered itself ....".

    Sorry for replying late. Here is the picture of the message that I get in the first boot after programming your "unpass" file. It requires a password again.

    Hi. Thanks for trying to help me. But this file (P70.bin) did not work. After programming I got nothing on screen, it is completely black. I even left the laptop on for more than 10 minutes to see if the problem is ME Region. But nothing.
    Any other suggestion?

    The laptop works with its original BIOS file but have password. I tested your files again and it does not work. I think the laptop change the code inside the BIOS after first boot. I am stuck at this point !

    Hi. In the past few days I have checked all the files that you have sent to me. I programmed the old BIOS file and it still requires password. Do you think the password is stored in the IO chip?
    I appreciate your help. Thanks
