Hello everyone,
I have a Lenovo ThinkBook 14 G2 ITL that is not working correctly and I suspect a corrupted BIOS. I would greatly appreciate your expertise in helping me repair my BIOS dump file.
Laptop Details:
Model: Lenovo ThinkBook 14 G2 ITL
Motherboard Model: FLV34 LA-K051P REV:1B
Serial Number (S/N): MP255LNT
MTM (Machine Type Model): 20VD003BRU
Problem Description:
The laptop has a black screen on power-up. The power LED lights up, and the fans spin, but there is no display on the screen . I have tried basic troubleshooting like reseating RAM, trying different RAM, and connecting an external monitor, pressing power button within a 60 sec etc, but the issue persists.

Thank you in advance, Alex.

Hello, Volinakis!
Thank you for your help. The fact is that the symptoms are the same before and after flashing. I also compared the BIOS files in "WinHex". The only difference is between the "U29" files. The "UC12" files are the same (please see the attachment). Maybe "UC12" was accidentally sent the same one?
Best regards, Alex.

nope, I used intel flash image tool to fix ME Region and bios image was split by the software.

volinakis No need to use FIT to clean ME on this one, just extract the BIOS from Lenovo website and split the 24MB file, first 0x800000 go to the 8MB chip, it contains Descriptor+ME region (already "Configured"), the rest 0x1000000 goes to 16MB chip

n40mail try this

ThinkBook 14 G2 ITL Laptop - Type 20VD
BIOS ver F8CN59WW
S/N MP255LNT
MTM 20VD003BRU
DMI 20000-207FF (on 16MB file)

Flash both 8MB (64) and 16MB (128) chips

really? But thanks for teaching me, I'd be lost without you!

[m1ch43lzm]

Yes really, extract the f8cn59ww.exe from Lenovo website with innoextract, then extract the second F8CN59WW.exe with platomav's BIOSUtilities from github, you'll get a 24MB .bin that has to be split

Couldn't find password in your BIOS unlike previous BIOSes in this thread, try flashing clean BIOS + DMI/Win key inserted

ThinkBook 14 G2 ITL Laptop - Type 20VD
BIOS ver F8CN41WW
S/N MP21G3XE
MTM 20VD000AFR
DMI 20000-207FF (on 16MB file)
Win key 92000-9203F

Flash only the 16MB chip if you only want to remove password, the 8MB chip contains Intel ME region; full BIOS is 24MB split in 2 chips 8MB+16MB, if your laptop boots fine not needed to flash 8MB (clean ME), I'm uploading it in case someone needs that version
