Maybe you need to check for a hardware problem .

 

[user0801]

do you have any idea what can i check?

Try to found RMRST PIN on the KBC IC and check if you get any voltage there if so the bios is good .

i cant find this one on kbc, but i checked BIOS chip and there is 3.3v

I think that your problem has nothing to do with bios and for supporting without schematic it’s not easy .
