Lenovos usually have a Model Type/Machine Type part number as well as a serial.
The bios youve tried already are ok,your problem is somewhere else.

Re: Lenovo IdeaPad L340-17IRH - need BIOS and EC dump
Check from the serial number that the bios has been downloaded correctly. Check the hardware again.Leave a comment:

Good morning, gentlemen, I hope you can help me with my laptop, I told you that I saved it about 2 years ago because it wouldn't turn on, now I have a ch341a programmer, I made a backup of the bios, I flashed an original downloaded from lenovo and it started, but it turned off after a few minutes, I entered the bios configuration and the brand, model, serial number, windows serial number, etc. did not appear, I request your help, I did everything I found in the forum but I could not solve it, also now it won't start again, it turns on but the fan does not turn, I will share all the information... -
So a couple of years ago i got a bios update through Lenovo Vantage, so i installed it and bricked my whole BIOS, so i couldn't fix it so i put that ideapad in a box, 3 years later i found that one PC and want to recover it to switch from a 2014 hp laptop to this one.
I found a method to recover the BIOS of many lenovo laptops tha consists in pluging in a USB Flash with the BIOS files and power on the laptop with Fn + R keys pressed until fans go loud and start beeping loud, but nothing worked, so i think filename is wrong, i tried naming the bios file as 07WW.BIN, BIOS.BIN, BIOS.fd,...10-11-2024, 03:12 PM -
Hello all,
I have a Lenovo Thinkstation P500 that is stuck at post with no display, it happened after I changed the memory timings in bios. I can not clear CMOS using the jumper on the motherboard, also tried re-flashing bios suing a USB stick but it also doesn't work. The only solution that I can think of right now is re-flashing the bios chip using an external programmer but the problem is that I don't have the bios dump of p500 for flashing externally and I don't know the location of bios chip. If someone can provide the bios dump and bios chip location it would be really helpful.... -

Hi,
first of all my apologies for my English (I don't speak it very well, I am French).
I am trying to troubleshoot a lenovo ideapad 5 15alc05 ryzen 7 that boots but remains in black screen.
I would like to know if anyone knows how to extract the .bin of bios from the exe published on the lenovo site. I have found several information on the internet but they don't work in my case. I think it's because it's an amd.
I found some dump on the internet but I don't really trust it. I would like to make a clean bis from the official Lenovo file...
