Try post # 13 https://www.badcaps.net/forum/troubl...50#post3571950
There's 2 BIOS chips on this board, one 25*64, another 25*128, it's always a good idea to backup the original BIOS chips before flashing another, to extract the DMI data and WIn key and transfer that to a new BIOSComment

Dear all,
I have recently fixed a Lenovo IdeaPad 3 15 ALC6 that was not booting due to a BIOS issue. After flashing the BIOS, the laptop boots up, but hard disk is not recognized in BIOS. Is says "Hard Disk : Not Installed". I have tried with 2 different drives (one that I know is working on another laptop) but I get the same result. I do not know if disks were recognized before I got the laptop and fix it, but I don't see any reason why not. I can boot on USB though.
Here the steps I have taken to fix the laptop:

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.... -
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 -

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...
