    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...

    BIOS Request - Lenovo Yoga L13 Gen3 (AMD)
    by maeson
    Hi dear Badcaps-Community,

    Somehow an auto update, which I triggered before I left my laptop unattended, bricked my BIOS.
    I was able to extract the 2MB BIOS and 16MB BIOS which I will attend. (CH341B black with NeoProgrammer 2.2.0.10)

    The Device is a Lenovo Yoga L13 Gen3 and I was able to identify the following specifications:

    Lenovo Yoga L13 Gen 3 AMD:
    Lenovo Modell: Type 21BB
    Artikelnr.21BB006GGE
    Seriennummer: PW0A6207
    AMD Ryzen™ 5 PRO 5675U
    Memory 16 GB DDR4-3200MHz
    SSD: 512 GB SSD, M.2 2242, PCIe Gen4, TLC,...

    Lenovo Yoga X1 Gen4 - Faulty Bios or what is going on?
    by AYsys
    Hello dear forum members,

    I own two Lenovo Yoga X1 Gen 4 laptops. One of them had a touchscreen problem, and I tried to fix it by externally flashing the BIOS. Unfortunately, I didn’t save the original BIOS and accidentally flashed it with a faulty one. After that, the device stopped working completely.

    I then had the idea to make a BIOS backup from the other Yoga X1 Gen 4 (same hardware) and flash it onto the non-working device.
    Nothing was flashed here — the BIOS was only backed up.

    I created the backup using a CH341A Black programmer and NeoProgrammer....
