My Xperia X just completely died.

Internet wasn't working some reason so I went to set flight mode on and off from the new top menu to try reset it.
Flight mode was taking very long to activate so I went to reboot the phone with powermenu.
As I press reboot and lay the phone on table I forget it and continued my working on PC.

When I picked up my Xperia it was off.
Now can't get any response. Can't get any leds or vibrations by holding any buttons or by using USB cable. I removed sim and tried fastboot mode or recovery mode but still no leds or vibrations.

Is there anything I can try?

Update:
Picked up my Xperia X once again and pressed buttons to try get any response and it just woke up and booted.
