and for context how all of this happend is when my uncle was using the laptop, he was doing some windows updates that included the bios update, but when the laptop took a long time with the screen fully off he turned it off and tried to turn it back on and thats when we discoverd that its basically gone.

hello!
I would like to ask for help regarding the following motherboard, see the picture. The notebook does not turn on, the power button only lights up, later the LED flashes, then stops. It does not draw only very little current 20V; 70mA. Can you send me a working bios?

Did you erase the chip before programming the new bios . Check your soldering. If it still doesn`t boot make a backup and post it, i want to check if the ME firmware has initialised

[ttmmttmm]

I didn't soldered the bios. I always delete the bios and check the new firmware to make sure it was entered correctly. I will try to upload it as soon as possible, thank you for your help.

[ttmmttmm]

I reloaded the original one, the power LED flashed when I turned it on, but yours didn't.

Sorry, I was just traveling, I just got back. I deleted it and re-wrote it, it won't start. The original one still started, the LED was lit... anyway, I read the error after trying to start it and I'll upload it to you, thank you in advance for your help!

The ME fimware state is still Configured , it should be in an Initialised state when the bios is read

Sorry, I don't understand what I should do or what not to do. Please write it down, I'm a beginner.

100% the bios you posted is not the original bios

This is the bios that SMDFlea uploaded for me (UX3402ZA.zip). I wrote it to the chip, tried to boot it (it didn't boot), then I read it back and uploaded it as UX3402ZA_test.zip. At least that's what SMDFlea asked for, or at least that's what I understood.
