    Upload both dumps here if you want help, it won't get any better with storytelling.

      I would much rather learn to fish than have someone hand me a fish... if that's not ok here that's fine just let me know

      I replaced the section that was mentioned here:



      with FF and 00 as the person I was quoting described



      but I think that may just blank out the BIOS password and not the power-on password (password prompt you get when powering on before you even get an option to go into the BIOS), hence why I was asking if anyone knew where to locate the user/power-on password in the dump

      but I attached it anyway if you don't want to share your secrets

        Ok, go fishing then if that's what you want.
        I said BOTH dumps, to be able to look what you've done, and not storytelling and pictures again.
        So I can be able to tell you where you're going wrong after you've failed already. That's what you want, isn't it?

            It turned out that the model is CF53-4, that's why I'm moving the comments to the "cf-53 mk2/mk4" thread.
            Below is your unlocked dump, you can compare mine and yours in hex editor to see where you went wrong:

                  Great thanks for quickly answer. But fact is that I have never worked either with bios chips or with the TL866II Plus programmer. Because, I ask you for a complete instruction for working with the BIOS chip.How i can upload bios ? What should I do first? If u have Video instruction for working woth Panasonic bios chips please share this video and i try to do it.

                              You dumped the wrong chip. W25X40CL is not the right one. Bios chip must be 16Mb, for example MX25L128 or W25Q128 and so on.

                                There is no other chip on this board labeled Winbound. Or I can't find that chip. Motherboard in front of me. This chip was next to the RAM.

                                  It doesn't have to be exact Winbond, it could be Macronix or some other brand as I mentioned. Inspect the motherboard more carefully.

                                      Good afternoon. Help me remove BIOS passwords from two CF-53s. I have 6 of these laptops. Of 4, I was able to remove passwords myself
                                      by changing the block at address AB0C7A - AEFFEF. But in 2 laptops this does not work. in the first case, BIOS number ACJ9TGRI12A
                                      It just asks for a password again. In the second case, BIOS CF-532SLZLNM shows a black screen.
                                      2 original dumps with corresponding names in the archive.
