    I don't understand why rookies likes him the most, probably because of the number 80 on the marking.

    Edit:


    Yes it is, that's the right one. Are you using a clip to read the chip?

    .
    Yep, the full aliexpress package.
    Freezes sometimes in the beginning, sometimes halfway.

    desolder?

    They probably assume it will be 8MB. Also sometimes it has the same package as the BIOS chip (SOP8/SOIC8).

    The winbond is a 25Q80JV 8Mb chip, but all I see here is 16Mb files for this bios.

    I used Neo programmer and a ch341 to read the bios.

    Am i missing something?

    is there a way to extract a bin file from a bios update?

    101.4 KB is far away from a good read. Try again be more careful.
    Use NeoProgrammer V2.2.0.10

    I tried it, but now the laptop has power but no video or boot up.
    Check to see if you have lost any small components around the bios chip (eg capacitors or resistors).
