I don't know if the Bios is corrupt or protected.
This is the beginning of what I read.
In other blocks there are 00 and FF

Thanks in advance

Hello!

Your BIOS seems corrupted. Reflash the BIOS chip with another dump. Don't forget to save the old dump.

Open a new topic in "DOCUMENTATION & BIOS/EFI REQUEST" department and ask for the BIOS dump. Don't forget to specify the major ICs markings according to the rules.

After programming the BIOS with the Matic file, it still does not boot, the data has been changed and edited with HxD for greater ease given the effectiveness of the program.
I understand that the power switch being part of the keyboard would be the same as bridging pins 1 and 3 of the keyboard connector
Can you give me the boot sequence?

True.

Not at all.
To simulate pressing the power button, bridge the pins 31 and 32 of the keyboard connector JKB1.

Checked, bridging pins 31 and 32 the laptop works correctly.
When verifying that the initial fault is the keyboard, I have reprogrammed the BIOS with the original file.
I ordered a new keyboard, after I receive it and replace it I close the thread.
Thanks in advance Matic.
