My NEC LZ750 started up with a black screen, and occasionally entered the system normally. After writing bios files dumped by others, it started up normally, but lost the activation information. Is there any kind person who can help me recompose the original BIOS information? Maybe need to synthesize the original ME into BIOS file dumped by others.please!

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... -
Hi,
I got a Lenovo Thinkcentre M75n (MT-M 11G5 PF3XG5V3) with a semi-bricked bios.
Short recap: I want to add an external GPU via the M.2 slot (Oculink). It does work but has some problems with the onboard GPU of the Ryzen 3 3300U. So I used Smokeless_UMAF to disable it. Since then I don't get any video via the external GPU nor the iGPU and Can't access the BIOS, but the PC does boot to the OS.

Hello Community,
I recently tried to change the Batterie on my Omen by HP Laptop 17 an104ng and after putting in the new batterie ([Batterie Link](https://www.amazon.de/7xinbox-17-AN0...&keywords=16%2... -
I need someone that can capsulate one of the bios files below, and i prefer the older bios version so i can flash it using CH341A tool into the bios chip.
The manufacturer BIOS files are bigger than the BIOSbackup1.bin files by 256KB and I don't know how to fix or recompile it.
You can see in this link a conversation between me and other people (Starting at page 10) who tried to help me (thanks to their efforts), but i still couldn't fix it and the laptop is considered as dead until now.
Also, I uploaded a backup file for the bios that I extracted by using CH341A...
