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.Comment

Hello,
I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
So I thought it was a Bios problem.
I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V.... -

Hi all,
I got a Lenovo Thinkbook 16P G2 ACH on the bench with a botched BIOS (somehow my client blanked it). I restored the laptop and got it up and running with original BIOS from Lenovo Support website.
My problem is now that the machine details are missing in the BIOS (Serial Number, MTM, etc.)
I tried to write the details with the Lenovo Uone Tool but had now luck. It is giving me an error: "ERROR: Locate protocol with LenovoEeprom, Status=[e]. EEPROM fail when reading or writing data."
I am now asking here for help if anyone knows how to do this in... -
Hello there.
I am working on a Lenovo Legion T5-26AMR5 desktop that currently has a corrupt BIOS and I have been unsuccessful thus far in trying to fix it myself.
History:
1. This computer came to me initially with an error message that said "BiInitializeLibrary failed 0xc0000001" or "0135 fan error". It would always be one of the two errors. It should be noted that when it produced the fan error, there was no physical problem with the fans. They were all spinning just fine.
I searched for this error online and discovered... -
