Re: Lenovo L570 bios neeg help
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 FilesLast edited by gungor1981tr; 10-07-2023, 08:18 AM.Comment

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,
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.... -
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... -
Need Clean BIOS/EC Bin File for Lenovo ThinkPad Yoga 11e - Stuck with 0275 Error CMS
Hello everyone,
I am attempting a repair on a Lenovo ThinkPad Yoga 11e that is currently stuck at boot with the error: "0275 error CMS" even after setup new bios battery and will not allow me to enter the BIOS/Setup.
This is a critical issue that I believe requires flashing the BIOS chip directly using a programmer (e.g., CH341A/RT809H), as standard software updates or resets are not possible.
I have opened the laptop and identified the main BIOS chip... -
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:
- downloaded latest BIOS from Lenovo Website...
