    Lenovo Yoga 9 14IAP7 bios

    I found 4 BIOS chips 3 from winbond and one giga device. I only managed to extract bios data from gigadevice chip. I tried guides that you sent me here yesterday but I guess I am not that good yet 😔 Can you please help me with this file as well. Thanks in advance.

      Now I have a very weird situation. The first one I read with ASProgrammer and that is GigaDevice 1,8V. The second one Winbond I couldnt read with ASProgrammer but I have made it with NeoProgrammer and Neo says that is 3.3V. So one chip I can do with ASP and other one with NEO. Is that ok? Hier is the second BIOS...

          Here I read it again but this time with NEO. It is not what ASProgrammer recognized. Now it says 3.3V. And ASP doesnt recognize the chip anymore. Here Is the first one also read with NEO. Thank you a lot.

            yep, next time read code from chipset, type it in google chrome and you'll figure out what voltage it is.
            Try bios extracted from update, write both chipsets.

              I did it and I have made some progress. When I put some pressurre on the red area i see a little bit light with bad colors shortly on the display as well. When I disconnect both display cables I can come into bios but keyboard nor maus are not working and with external as well. Thank you a lot for your help. I dont know where to start now I was assured that it was bios 😔 and there is one more winbond chip.
