How to awake my hard bricked phone?
Try to remember how You used to connect it before and touch the areas of touch screen that were used back when phone responded. Perhaps it is just display that went off. This might be cheked by charging - if during charging display is dead then it is dead (obv). But if it responds - problem might be in a touchscreen or the power button.

But for best solution try to take your device to a service centre.
