Microsoft Windows 10 (64-bit)

So, there is story. Today i wanted to update BIOS. Everything went clear (without errors and others). Just after rebooting from updating thing, laptop went off. Just blinking (i think it's battery) diode. I couldn't do everytning and then i found solution. On laptop without power i was holding mute and power button, Success -  my little friend was alive (and another but), keyboard is not working properly fe: 'x' is '/' 'windows_button' is '\' and etc... completly not useable. Tried reinstalling BIOS but it doesnt help, also i tried windows key + b, but all the time there is black screen. Any solutions?

Note: keyboard doesn't work even if i click f9 to go bootmenu, all the keys are mismatched.

checked for numlock, usb keyboard works normally, built in keyboard is not detected
