only the middle led (battery) is on. 19V input ok. Pin 8 of the memory with 3.3V ok. I'm thinking that just recording the CMOS memory for the notebook to come back to life because it was only after the SSD card was inserted that the notebook no longer turns on.

I managed to find a schema and a bios, but first I will analyze it to see if these files are useful for me.
I tried to attach the schema and the bios file but I couldn't, it exceeds the allowed size.

the defect of the notebook is in the power key that is defective, it could be the power key (which is part of the keyboard) or the bios. In this case the problem was the defective key. I connected pin 29 of the keyboard connector to the ground for the notebook to work again. Topic closed.

I managed to do a complete test on the motherboard and also on all keys on the keyboard just by finding the power key with problem (on-off key that is part of the keyboard). The other keys on the keyboard are fine.
