Hi there, please could someone have a look at my bios bin file. I believe the bios to be corrupted as my Lenovo yoga c740-14iml will not turn on at all with the battery charged and all other possible issues checked. Board is FYG41 NM-C431 REV 1.0. Just a slow pulse of power led, pressing the power button does Nothing. If the corrupt file cannot be used in anyway, could someone send me a clean original bios bin file adapted to use. This would be much appreciatedComment

Already done this, I've unsoldered then soldered it on a CH341a to read the data, i saved the original bin file, only once though. I then erased the chip thinking I had the replacement file, I know a noob thing to do. Also I didn't realise the file should be a few mb. This was before I came here, I was hoping originally to write the update file from the Lenovo website to the chip via the Ch341a, thinking just write a bin file but none contained in the download. The file I sent earlier is the dump from the chipComment

Summary of BIOS Whitelist Removal Problem
Problem:
I am attempting to remove the WWAN card whitelist from my Lenovo ThinkPad T560.
Initial Findings:- My current BIOS version is N1KET58W (1.45).
- I have a CH341A programmer and have successfully created two full backups of my BIOS.
- I have the ability to use command-line tools on a Linux machine.
- I attempted to use several automated and manual patching methods on my N1KET58W (1.45) BIOS, including using hex strings. These attempts all failed.

Hello dear forum members,
I own two Lenovo Yoga X1 Gen 4 laptops. One of them had a touchscreen problem, and I tried to fix it by externally flashing the BIOS. Unfortunately, I didn’t save the original BIOS and accidentally flashed it with a faulty one. After that, the device stopped working completely.
I then had the idea to make a BIOS backup from the other Yoga X1 Gen 4 (same hardware) and flash it onto the non-working device.
Nothing was flashed here — the BIOS was only backed up.
I created the backup using a CH341A Black programmer and NeoProgrammer.... -
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.... -

I've currently got a Lenovo Yoga Slim 7 14APU8 that is not posting. Its fan spins, the keyboard lights up, and the caps lock doesn't work. It was taken to some shop for cleaning, and then they updated or tried to update the bios. After that, there was no display and no post. I've removed the bios ic from the board and made a bios dump. I need some assistance going forward, as I suspect this is probably just a bad bios issue. I've tried searching for a dump, but no luck; if anyone can throw me a bone, it would be much appreciated!
Attached is the bios dump in the state I received it...
