Lenovo ThinkBook 14 G2 ITL FLV34 LA-K051P bios

[n40mail]

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

Hello!
Thank you for your help. I'll try to flash the BIOS in a week.
Best regards, Alex.

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

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.

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.

Thanks again M1ch43lzm, works a treat. Total legend!!

Kind regards

[twonk9098]

Thank you, will update you.

Many thanks for your help.

[m1ch43lzm]

8MB BIOS chip has ME region, the 16MB has the BIOS-UEFI region, I already added your DMI+Win key there

[twonk9098]

Thank you, which file (8 or 16mb) do I replace the DMI / Win information?
Many thanks

[m1ch43lzm]

Try, BIOS extracted from Lenovo website

ThinkBook 14 G2 ITL Laptop - Type 20VD
BIOS ver F8CN59WW
S/N MP1YGF4K
MTM 20VD000AUK
DMI 20000-207FF (on 16MB file)
Win key 92000-9203F (on 16MB file)

[twonk9098]

Sorry, the laptop serial number is MP1YGF4K.

I note though that using a previous bios uploaded in this thread for someone else, I replaced the 128mb and 64mb bios's and the serial number within the Bios has not changed. Is this right?

Thank you

Hi,
I have Thinkbook 14 G2 ITL. I have had a few issues with it and all was working for a while, until I upgraded the memory.
After upgrading, the screen no longer lights up or functions.
I have installed another bios from an earlier post and the laptop display now works however,

The battery charging is a little intermittant, I never had issues with the battery / charging until I changed out the bios.

Is someone able to repair my original bios please?
Both files attached.

Thank you

Thanks, but that was toa nother user. but i tried it too, and stays the same. This mainboard as another memory, a winbond 25q80dvsig, close to charger port. Someone knows what it does, and have a backup?

Your laptop is ThinkBook 14 Gen2 ITL not ThinkBook 14s Yoga ITL, even if board number is the same the BIOS is different for the Yoga model
Post 132 is the correct BIOS for your laptop, hoaca388 extracted it from Lenovo website

You can try post 124 or 125, it's an earlier BIOS version, that will change your S/N if it works

The W25Q80DV is likely USB-C PD controller firmware, if laptop gets 20V on USB-C meter it's fine
