    I want to migrate the BIOS of Lenovo ideapad 720S-13IKB

    Hello.

    I have a Lenovo ideapad 720S-13IKB.
    It powers on and the CPU fan works.
    I have a Lenovo ideapad 720S-13IKB and the power is on and the CPU fan is working, but the BIOS is not up and it keeps turning on and off.

    I got the attached OFFICIAL BIN file from the internet, which is made from LENOVO's BIOS update EXE file.
    (OFFICIAL_FromUpdateEXE.BIN)
    I FLASH'd this BIN file into the BIOS using CH341A and AsProgrammer.
    BIOS came to be started up.

    However, when I looked at the BIOS screen, ProductName, MTM, LENOVO SN, UUID, etc. became INVALID.
    Perhaps because the UUID has changed, I can't even activate the reinstalled Windows 10.

    The BIOS chip says winbond 25Q64JVSIQ 1805.
    I am attaching the original BIOS backup file before FALSH.
    (original.bin).

    I want to migrate the previous ProductName, MTM, LENOVO SN and UUID so that the OS can activate the license.
    Can someone please help me with the migration process?

    Thank you very much.

          I am sorry for the delay in replying.

          I just flashed the file you gave me to the BIOS.
          ProductName, MTM, LENOVO SN and UUID were migrated.
          I was also able to activate my Windows 10 license.

          Thank you very much for your help.


          I would love to know how to do the migration.
          I have a few questions.

          Are the ProductName, MTM, LENOVO SN and UUID in the DMI information?

          How did you identify the area of DMI information this time?

          Does the location and length of that DMI information area vary by manufacturer, brand, and model?

          Do you want to copy the original DMI information that you identified and overwrite the attached OFFICIAL BIN file with HxD program or something?

          Do I need to rewrite anything other than the DMI information?


          Please help me.

              Lenovo IdeaPad 3 - Hard Disk not recognized in BIOS
              by mkdj
              Dear all,

              I have recently fixed a Lenovo IdeaPad 3 15 ALC6 that was not booting due to a BIOS issue. After flashing the BIOS, the laptop boots up, but hard disk is not recognized in BIOS. Is says "Hard Disk : Not Installed". I have tried with 2 different drives (one that I know is working on another laptop) but I get the same result. I do not know if disks were recognized before I got the laptop and fix it, but I don't see any reason why not. I can boot on USB though.

              Here the steps I have taken to fix the laptop:
              - downloaded latest BIOS from Lenovo Website...

              Lenovo IdeaPad 330 15-AST 81D6 BIOS Recovery
              by jendkkd jeje
              So a couple of years ago i got a bios update through Lenovo Vantage, so i installed it and bricked my whole BIOS, so i couldn't fix it so i put that ideapad in a box, 3 years later i found that one PC and want to recover it to switch from a 2014 hp laptop to this one.

              I found a method to recover the BIOS of many lenovo laptops tha consists in pluging in a USB Flash with the BIOS files and power on the laptop with Fn + R keys pressed until fans go loud and start beeping loud, but nothing worked, so i think filename is wrong, i tried naming the bios file as 07WW.BIN, BIOS.BIN, BIOS.fd,...
