                  I have an 500e (1st gen) and having issues reading the bios chip. As far as I can see, its a Windbond 25Q128FW. I can't find that exact model in my programmer software CH341a Programmer 1.13. When looking up the SoC, it seems it's on 1.8V, so I assume that's what I should set my programmer to? In the software, I pick the closest SoC I can find, which is W25Q128BV. When I read it, it only returns all FF or 00. Any pointers to how I should proceed? Get another software? if so, which one? Change voltage?

                    Use NeoProgrammer software. The 25Q128FW is 1.8V

                        I tried NetProgrammer too, but I get "no response from IC" when using it. Do I have to desolder the IC? I prefer to just use the aligator clips.

                                          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....

                                          [REQUEST] Dell G3 3579 BIOS Password & AMI Protected Range/BIOS Guard Unlock
                                          by zenius
                                          Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.

                                          Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...

                                          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,...
