Hello! I need help getting a modified BIOS for my system. Since I have an engineering processor, is it possible to add the microcode of this engineering processor to the latest BIOS for this laptop model? I think since the BIOS is old, that's why the Wi-Fi driver is not installed on Win10 and Win11, the sound is not adjusted (error code 10 in the device manager) and the screen brightness. The laptop also has BIOS chips W25Q512NW and W25Q128JV, how can I read and flash W25Q512NW, the chip is not read by my ch341a programmer, and W25Q128JV is read as clean, although maybe this is true?

How did you manage to make this bios content?? What programmer do you have??

[Gangubasus]

ch341a programmer with modification to 1.8V (replaced 3.3V converter to 1.8V), read using NeoProgrammer program

The bios chip must be unsoldered from the board before writing or reading..
do not use the clip, you may have errors..if you do not have anything to unsolder it with,
solder wires between the programmer and the bios chip..

here is a video for example..https://www.youtube.com/watch?v=DWWi...nnel=ThisIsHow

the chip was unsoldered and read directly from the programmer. In my opinion, everything was calculated correctly

is the bios posted on the chip?

I read from the W25Q512NW microcircuit, the dump is attached above in the message

ok..in the first post you say that you can't read the chip with this programmer, then the bios appears, without any clarification..I hope you managed to read it correctly..

Yes indeed at first I couldn't read the BIOS, even with the board with a converter to 1.8V, but after I replaced the converter on the CH341A itself from 3.3v to 1.8V, the firmware was read. Please help me add the microcode from my dump (if possible serial number) to the latest BIOS from the official site.

You can`t update Engineering Sample microde with production microcode.

As far as I understand, if you add the microcode of the engineering processor from the dump to the new BIOS, then everything should work or is it not so?

Can anyone share their BIOS dump from this laptop model?

Need a BIOS dump for flashing, maybe someone has one or is it possible to extract the BIOS firmware from the update file from the official website?

Hello everyone,

To start, I am sorry if the information I ask for is in one of the stickies or somewhere else on the forum. I am new, and a lot of the terms used here are unfamiliar to me.

Last week I bought a Lenovo X1 Carbon Gen 12 from a trusted vendor. Unfortunately, the system is locked with a BIOS password. I tried to read the sticky and follow the steps, but honestly, things like this are not my expertise.

My questions are: is it possible to remove the supervisor password on a newer laptop like this? If so, how?

post merged..next time look for a thread with the name and model, motherboard model of the laptop, and post there, if you can't find it, then make a new thread..
