      Re: Lenovo 14W

      I'm using the CH341A, I don't have another original bios backup.
      Is there any other way to fix the motherboard?

        Use NeoProgrammer or ASProgrammer software. Are you using a clip ?

            Remove your bios chip from mainboard.Ch341a used with clip is very prone to errors when reading/writing.

                        Hi everybody, I'm also stuck with a laptop featuring this motherboard. It is fully locked, bios and OS side. I guess my only choice is to reset the bios on the chip directly, but I just can't locate it on the motherboard ? Nothing is labelled CMOS/BIOS or anything like that. Does anybody, by chance, know where this chip is hiding ?

                                  and if you find the bios chip, you need an SPI programmer to read and write the content..here is a video for information..

                                    I can confirm hoaca388's binary works like a charm. For those wondering which chip is the bios, it is near the battery (the big one) and is labelled XMC. You can read/write it with ASprogrammer easily, I didn't had to desolder it, the clip worked perfectly.

                                    Cheers. Thanks for your help !
