    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...

    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....

    Lenovo Yoga Slim 7 14APU8 Bios Request
    by beogeek
    I've currently got a Lenovo Yoga Slim 7 14APU8 that is not posting. Its fan spins, the keyboard lights up, and the caps lock doesn't work. It was taken to some shop for cleaning, and then they updated or tried to update the bios. After that, there was no display and no post. I've removed the bios ic from the board and made a bios dump. I need some assistance going forward, as I suspect this is probably just a bad bios issue. I've tried searching for a dump, but no luck; if anyone can throw me a bone, it would be much appreciated!

    Attached is the bios dump in the state I received it...
