    Clean ME region - a bit of theory

    Hello laptop repair experts,
    can someone plese, help me understand the significance of cleaning ME region in a BIOS dump file?
    I know that Manegement Engine (ME) data is part of BIOS/UEFI firmware. I know that it contains some HW specific data for the particular laptop.
    What I don't know, why do I need to clean ME region if I try BIOS dump file from another laptop (of course same type and model). I'm not sure if this is only because of the serial number (not sure if that is stored in ME region at all).

    Recently, I had a two cases where laptops (one is Lenovo Idepad S400, other is Asus X555) came to life after reflashing BIOS with dump files found on the internet forums.
    In both cases clean ME region is not done. What I notice is that in both cases, it takes significant more time for laptop to start after power on, but after that everything works normal. I haven't noticed any other problem.

    Maybe this is exception, but is cleaning ME region really that important?

    Thank you.

      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...

      Hello guys,

      could I please get some help cleaning the ME region of the attached Zbook 17 G1 bios dump (CH341a, neoprogrammer, chip-desoldered, dumped twice, identical checksum)?

      Symptoms, delayed BIOS post (ca. 45 secs.) keyboard not working, touchpad not working, booting linux live, console says "Management engine not configured".
      I tried following the ME firmware cleaning guide, but whatever Flash Image Tool version I try, I get the same error:

      I need a BIOS dump for the Samsung S49CG934SU monitor
      by Habble7
      The Samsung S49CG934SU monitor does not power on - no LED indicator activity and no response to power button. However, when 21V power is connected, it immediately draws 0.8A of current with no display output. The motherboard processor gets warm, and there is continuous reading activity from the W25Q128BV BIOS chip.

      Suspected Cause:
      I suspect the BIOS may have been corrupted during a power interruption while updating the firmware. The official website provides firmware updates, but they can only be installed via USB flash drive.

      Troubleshooting Attempts:

      DUMP DVR HIKVISION DS-7208HGHI-K1 (80389 Rev 1.3 Firmware)
      by Mephysis
      Hello guys i really need help, i recently updated my DS-7208HGHI-K1 and it somehow got bricked, I've got it up and working now by flashing a new dump file i found but the serial number is really wrong and the uploader of the dump file probably intentionally did it.

      I still have the bricked dump file is it possible to transfer the serial number of the "bricked dump" to the "working dump"?
