The Acer Chromebook C710-2847 is part of Acer's line of low-price netbooks running Google's Chrome OS. The devices are simply constructed needing just one screwdriver to take them apart.
Try charging it, maybe it ran out of battery life. Or maybe the power button broke from water damage. That happened to my older chromebook. If water damage is the case, try closing the chromebook than opening it again. Good luck!
