Set a bios password then try to disable it. If that doesn`t work patch it using the Autopatcher or use a pre-patched bios https://www.badcaps.net/forum/troubl...ection?t=81573

hi, I bought a lenovo x270 with of course a bios code, the chip is a winbond 25Q128JVSQ(1736)
I took a CH341a to try to save this story, I tried with the Neoprogrammer which found me chips but I'm not sure of the results,
maybe someone could look I didn't like killing it ^^
thanksComment

Hello.
I could really use some help unlocking this Bios password for my Lenovo x270.
I attempted to use the autopatch, however I was not able to run the command (obviously I'm doing something wrong) and I've tried using a pre-patched version which gave a blank screen.
Bios is attached.
Serial no: PC-0RE4MJ

I extracted the bios of my new (refurbished) Lenovo X270 because the bios is locked and prevents me from reinstalling (I can't boot from an usb key).
You can find the bios attached. Can you please help me unlocking it?Comment

I finally downloaded the lenovo-patcher in order to patch the extracted bios. I manage to get it right and to remove the supervisor password.
Fortunately, I found a 64 bits system in order to run the lenovo-patcher, as my main computer is a 32 bits processor.
Thanks for this tweak!Comment

Hello,
my x270 suddenly got bricked for no apparent reason. When I press the power button the keyboard and the button light up for a few seconds and then turn off again. I've tried the usual fixes like draining the CMOS battery and so on. I've now used a CH341a to back up the bios and flash all other ones I could find, to no avail. The furthest I got with some is that it would beep at the end in addition to what it did before. Can anyone help me?
I don't know how helpful this will be but this is what I was able to find out about it:
TYPE 20K5-S0B700 S/N: PC - 0SURKD 18/02
BIOS chip: W25Q128JVSQ 1740
Thanks in advance.Comment

Recently I used the official Lenovo bios updater software on my ThinkBook 13s G3 ACN (20YA0005GE). The updating process failed and I got a black screen after powering the device. Of course I did not make an own backup before using the Lenovo bios updater.
I bought a CH341A programmer and was able to make a connection to the chip while it is still soldered on board. But I did not realise that the chip was a 16MB size and selected the wrong size (8Mbit / 1 MByte) before reading the content of my chip. So the dump I did before erasing the chip is only 1MByte big. I fear that I lost... -
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

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...
