I don’t know Russian. Anyway, please read my updated post on solution to the problem. My Aerobook is 13", yours is 15.6", but your motherboard and the keyboard connector look very similar to mine, so the keyboard ribbon shorting out pins 27 and 28 permanently is probably occuring in your laptop too – however, I can’t make out on your photo whether pins 25 and 26 are disconnected like on mine. First thing to check is whether the power-on lines (pin 27 and 28) are shorted permanently when the ribbon connector is inserted, and disconnected when the ribbon connect is removed. If so, find a way to disconnect them, and a way to short them only when you do the power-on action of pressing the power button.
