i've flashed main and ec but no lucky: the power light keeps blinking 12 times and after turn off it restart every time in an infinite loop.
Also if i reconnect internal battery, the power light go on and after a while it turn off
the last screen before the problem was a lenovo screen with this messages: Warning: Please do not power off while BIOS self recovery processing and when it reached 100% it turned off and never turned on again.
Bios was upgraded by Windows 11 Update.Comment

Wrote the first file 16MB in size after I made a backup first which is also 16MB in size, and now it behaves a little differently, but still no power ON laptop. I read also the second chip near it which is 8MB in size and uploaded here if you can help me, thanks so much
P.S. I didn't wrote the second file that you have here which is 256 KB in size as my second BIOS chip is 8MB in size after reading backup..,,Comment

As I wrote this 16MB file and it did not work, now I notice that there is a fresh new BIOS uploaded on Lenovo site, but I am unable to extract both the firmwares.bin from that file using this tutorial here:
https://github.com/liho98/lenovo-bio...traction-guide
Can you help us out or tell how to do extraction of this new file here at this link?
https://pcsupport.lenovo.com/us/zh/p...eapad-1-15iau7
It seems that on the original file from Lenovo (JKCN50WW) which is around 26 MB in size, are packaged both BIOS-es the one 8 MB in size and the 16MB in sizeComment

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... -
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... -
Hi,
I want to remove the Bios Password of my Lenovo IdeaPad U330p with the Lenovo autopatcher. I have the CH341A Black and I'm using NeoProgrammer. The Programmer has an LED that indecates when it reads or writes the Chip. When I try to Connect my Programmer to the Bios Chip (Winbond 25Q64FVSIQ) the LED lights up even though I didn't click on Detect botton in NeoProgrammer. If i click on Detect the LED still remains on and NeoProgrammer says "IC not responding".
