I already figured it out myself and deleted the passwords on these versions as well.

You must post the laptop serial numbers.

I'm sorry.

In the second case, there are no stickers with serial numbers. There is only FCCID: ACJ9TGRI12A

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.

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 day! Finally i can find BIOS chip and dump it. Can u check this BIOS and repair if its broken ?

Re: Panasonic touchbook cf-53 mk2/mk4

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.

Re: Panasonic touchbook cf-53 mk2/mk4

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

Re: Panasonic touchbook cf-53 mk2/mk4

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:
