    Not possible via patching BIOS. You need to read MEC EC chip with RT809 or Vertyanov Programmer to remove password.

                post bios dump and I think i can help you patching it. I was able to unlock an X395 with AMD and 128Mb bios chipset.

                            Hi, I dumped W25Q128FW_1.8V, patched with autopatcher, but when booting with it - melody.
                            Is this the correct chip to patch?
                            If it is the correct one, I would appreciate help.

                                  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....

                                  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...

                                  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,...

                                  Hello everyone,

                                  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

                                  by abhorsen
                                  Hey guys,

                                  Hope you all are doing well. I come here from Win-Raid because I am having issues disabling Flash Protection Range Registers so I can flash my BIOS from within Windows using Intel's IFW tool/using flashrom within Linux, however I cannot due to the above mentioned error.

                                  Here is my thread on Win-Raid detailing the whole process I went through: https://winraid.level1techs.com/t/re...h-gen/95478/27

                                  Essentially I managed to boot into Windows while shorting PINs 1+5 of my audio chip to disable the HAP bit...
