yes i can try any bios dump provided here, but i don't had enough info when i use tools (also provided here) to enter those DMI info.
just hoping someone would extract those DMI info from the pictures i took, also lenovo support site doesn't provide any info i need

the bios from post # 204 is virgin, use the HxD program (it's free on the internet), enter both bios into the program (your laptop and the virgin one),
select that interval mentioned in both bios, copy the interval in your bios and pass it to the virgin bios (copy - paste)....and that's it...

yes sir, i usualy used HxD program to move DMI info to a new bios with help UEFI Tool program, but on this bios i couldn't find it.
though i couldn't fully understand when you said "select that interval mentioned in both bios", i manage to compare and locate DMI area using bios from post 252 & 253,
sadly on my bios dump those area is empty

as per your suggestion, since i don't have any info about the unit i worked on (sn, uuid, mtm, etc...) i use info from un-repairable unit with same model and ofcourse used U1 tool too insert those info & worked.
dead "ID" on repaired unit 😅. Thank you for the guide sir

Hi, could someone help me with my corrupted BIOS file? For context, when I turn on my PC the power button LED lights up, the fan spins but the screen stays black. I tried some BIOS files from this thread, but to no avail.

Thanks for the reply!
I tried to extract the BIOS file from bios.cap and then followed the guide on how to copy the DMI information (as explained in the link that you provide, following post #1, the file attached to post #12 is not available "Invalid File Specified"). I flashed the .bin, turned on the PC but the screen remains black (no backlight), then I turned off the PC, pressed the Novo button for five seconds until I heard a "beep" from the motherboard, the PC turned on, the screen showed the Lenovo logo, then the boot manager and 2 seconds later the screen went black, I tried to turn on the PC again with the power button, then with the Novo button but it did nothing, just black screen, so I was curious if the Novo button did "something" to the BIOS file, so I made a dump of the IC and compared the .bin I flashed and the .bin from the dump with winmerge and found that the file in the IC was modified, I will attach the newbios.bin and the extracted.bin, now I have no idea what is going on

Thanks in advance!
