    How to transfer information from one BIOS to another?

    Hi.
    I am starting to learn about UEFI BIOS.
    At the moment I have Lenovo laptop with bad BIOS.
    I tried to clean ME region and transfer EC region from a known working BIOS, but the laptop does not POST (just fan spin).
    So there is something else bad.
    If I flash a know working BIOS, the laptop POSTs and boots into Windows.
    But the problem is, that the serial numbers, Windows key, and every thing else is from another laptop.


    Where do I start to transfer the S/N, Windows key and other information from one BIOS to another?

    Thank you.

    Hello,

    I think it’s not the right forum section you have a dedicated section related to bios.


    You have to copy DMI informations.
    Location dépends Of the brand/model Of laptop.

    For Windows serial search in hexa :

    010000000000000001000000000000001D000000

    you can read that too:

      ASUS ZenBook UX480F : need help with cleaning the ME region of my BIOS dump
      by mkdj
      Dear all,
      I have a ASUS ZenBook UX480F with the following symptoms:



      I suspect it is a BIOS issue. So I decided to try to clean the ME region. I followed the guide on win-raid, and I believe I have done everything correctly. My problem is: when I open the outimage.bin in ME Analyzer, it says that it is Extracted, and not Region, Extracted as it should be. Is it normal, or did I do something not correctly? This is my first experience editing BIOS files.

      I would appreciate if someone could take time to explain the issue, so that I can learn. But I would...

      Bricked bios from a legion y540-15irh (81sx) . Needing dmi/clean me region maybe
      by Lexsmash85
      Edit: apologies, I only need help with the DMI info.. I thought the ME region would need attention in order to recover from bricked state but maybe I misunderstood.

      Im a novice to this experience but in short, I performed a backlash from the latest and final bios firmware BHCN45WW to BHCN26WW hoping that would solve an issue with keyboard functionality failing after an update. Ended up hanging during flash process and then system would no longer POST on reboot.

      USB recovery process didn't seem to take. So today I successfully managed to get the BIOS dump from my machine...

      ASUS TP500LA BIOS request/repair/merge?
      by jbonavita
      Hi, my laptop wont boot at all
      With original bios no POST, only LED lights
      With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
      Some issues
      A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
      B- If updated from 500LN version 203 to 300, the battery stops being recognized

      Things I tried

      1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble...

      Lenovo Thinkbook 15 G2 ITL i5 (serial number: MP2BFZEF) bios request
      by Wahaz
      Hello,

      I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
      So I thought it was a Bios problem.
      I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V....
