    LA-L051P Changing ME Region

    Hallo,

    I've replaced Intel CPU SRKH5 with burned PCH on the LA-L051P with SRKH4 (i7-11370H to i7-11375H) and now I see that this was the easy part.


    Now I need to replace ME Region using this from the donor board - 15.0.47.2473 and need help from smarter people than me.

    The only ME in version 15.0.47.2473 I've found has 3,125,248 byes, which is strange size.

    Using HxD and selecting 465000, selection ends in the middle of code to check the size of extracted ME. It doesn't seem to be right.

    I couldn't find Intel Flash Image Tool in version 15.0.10.1469.
    Can I use another 15.0.xx, or it has to be exactly the same as ME Analyzer shown?

    Could you please tell me if I'm doing something wrong and where to find FITool in correct version?

    Thank you in advance!

    I see now that I should post this in the 'BIOS Requests ONLY!'
    Is there a way to move it?

              Thanks volinakis! With this BIOS motherboard behaves differently. Reacts on PW_ON and goes on 0.065A, stays 10 seconds on and then turns off. I see under thermal camera PCS is getting a little temp but CPU is staying cold.

              In the meantime I've studied more and found program UEFITool NE alpha 67 which is showing different information about ME Region than MEAnalyzer. Using this information I've copied ME from the donor board bios to my BIOS. Now current after powering MB on goes to 0.900A for 3 seconds and powers off... Both PCH and CPU are getting hot.

                nope, is not working transferring ME_Region from a bios to another, you have to use Intel Flash Image Tool to replace ME Region

                  Clean ME region - a bit of theory
                  by Adenitz
                  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...

                  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...

                  bios txe region y116te_e_glk
                  by eenee
                  It's possibly a Chinese offbrand laptop that uses a generic series of motherboards called y116te. It has no image.All power rails are working. No bios dumps could be found on the internet. Tried similar bios from this thread. No difference. I wanna try cleaning the TXE region of the bios but cleaning TXE region seems too advanced for my skills. Please help clean the TXE region from this dump ...

                  Acer Nitro 5 (GH51M LA-K861P) Clean ME Region
                  by Jasonexe
                  Hello everyone,

                  I got a Acer Nitro 5 gaming laptop that recently stopped working. I found out that the 3v rail was shorted because of a dead PCH so i ordered a replacement already and i'd like to clean up the ME Region from the bios dump i made with my CH341A programmer (modded to 3v). I used ME Analyzer along with the other tools needed and came across a issue where i can't replace the ME Region with the other file because the size is too big ? I'm not completely familiar with this and i'd like to know what i would have to do to fix it....
