I can patch it for you if it asks for a password, just upload that particular bios. -
Re: Lenovo L570 bios neeg help
Here you go, please report if successful, maybe we can clean the ME region later, but I'm leaning more towards replacing the bios region from Lenovo Update. Instructions included. Saludos desde Texas.Comment

Re: Lenovo L570 bios neeg help
I forgot to add in the instructions, look for any switches, they must be pressed when doing the unlock. Usually they are pressed when the backplate or bottom cover is on, so if you just put the cover back, you are good to go.Comment

Re: Lenovo L570 bios neeg help
It works no longer has a password, now I only have a delay of 20 to 30 seconds to show the logo, the bi that you uploaded patched backup_SPI_786.rar, it did not work with that one, I had read about the lenovo autoparcher, so I tried it in my computer, and it gave me a different bin, and with that it allowed me to remove the password, the read1 file that I uploaded at the beginning, does not give an image, as I understand it is for the region me, I have tried without results
edit,
I upload the .bin that works for me although it has a delay, I update the newer version through a cd, it remains the same, I extracted the region from a L570 forum file (type 20JQ, 20JR) (20J8, 20J9) (ThinkPad) N1XET63W LA-C422P, and use that version of the me in the original read1 and in delayed file, without giving imageLast edited by Carlitros*way; 04-12-2021, 01:58 AM.Comment

Re: Lenovo L570 bios neeg help
The necessary arrangement has been made
I don't know enough English and program usage, I'm not a very good mechanic, but I'm curious
I'm sorry if I did it wrong.
I've tried most of the files published here, but I couldn't get an image
although the usb 3.0 outputs are not close to a short circuit, there is a leak, most likely the embedded cpu is gone, but I couldn't be sureAttached FilesPremium supporters get full download access and other benefits.

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 everyone,
My Lenovo Legion Y540 (i7-9750H, RTX 2060) bricked after I downgraded from BHCN44WW to BHCN21WW.
Laptop stopped booting entirely.
I used a CH341A programmer to dump the corrupted 16MB BIOS.
i then attempted the following:- Downloaded stock BIOS BHCN39WW from Lenovo
- Trimmed it to 16MB
- Extracted the BIOS region from the corrupted dump
- Extracted the BIOS region from the stock 39WW
- Replaced the corrupted BIOS region with the stock one (within hxd , opened the corrupted dump and replaced its region by the stock)
- Injected back my LDGB / DMI
