Thanks. I flashed BIOS but no result.
Maybe it's not a BIOS...?

What programmer are you using to make the backup with. In the picture is what you posted on the right, and on the left is what it should look like after i converted it. Your backup should be in hex

I am using the CH341A Programmer and I will give everything I managed to save, and now I don't know what to do.

I am using AsProgrammer_1.4.1. And there is nothing left to do, unfortunately.

Make another backup this time with NeoProgrammer, post it here, if it`s the same then will look at other options.

I flashed the BIOS with the programmer you suggested, and the laptop, as always, reacts to the start button; the LED lights up, then the laptop responds to FN+ESC, the LED stays on when pressed, then the chips play around, and after a minute, the fans start running at full speed and the laptop shuts down. If I remove the RAM, the laptop doesn't start in both slots, but it starts when the RAM is in one of the two slots.

If you put some pressure on the cpu it will probably start, if so the cpu needs reballing.

It seems that the processor is dead. Thank you for your help.
