        hi Mate, I have the same problem with the same laptop. First of all, thanks for the bios files. One question, I use the CH341A tool to flash the BIOS. The main BIOS has the chip MX77L25650FMI42A. Unfortunately, the programs for the CH351A tool do not have this chip in the data. did you flash the chips too? If so, how did you solve the whole thing? For completeness, the backup chip MX25L25673G is available from Neoprogrammer. best regards and thank you very much!

          Hi Guys
          My Laptop most likely bricked due to BIOS...?
          Resetting no success.
          Now i took out the bios chip out (MX25L25673G) and read the bios in the RT809F ISP Programmer.

          Can someone provide me with a working bios to flash on... as a last resort chance...

          model: Thinkpad L15 Gen 3
          motherboard: ??? (2022/06)
          serial number: PW-02H7WX
          type number: 21C3-006LMZ

          Thank you

              Lenovo Thinkbook 15 G2 ITL i5 (serial number: MP2BFZEF) bios request
              by Wahaz
              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....

              Lenovo Legion T5-26AMR5 Desktop - Corrupt BIOS
              by grimacelord
              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...

              Lenovo IdeaPad 330 15-AST 81D6 BIOS Recovery
              by jendkkd jeje
              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,...

              So far I've been a silent reader, but now I need your help

              I bought a laptop. The seller said the bios was locked. I was looking for a way to remove this ban.
              I then got the CH341A and pulled the corresponding files from here https://www.badcaps.net/forum/troubl...evices-and-ele...
              The laptop was brought in with a BIOS problem and a password. After reading the dump, the information was damaged. I ask for help in the BIOS with a clean ME region. Motherboard 213035-1. Serial number: PW+04e998, Type number: 21c3-0016ge
