It may very well be that your keyboard is broken, as the power button is connected to the keyboard. To see if this is actually the issue, locate the power pads on your logic board as seen in the accepted answer by oldturkey to this question [https://www.ifixit.com/Answers/View/197784/Power+on+pads+for+Mid+2012+MacBook+Air+11%22+A1465|here]. Using pair of tweezers, touch both of the pads for several seconds with the battery and all other components in the machine. If you hear a startup sound and the machine turns on, then you know that the keyboard is damaged, and that is about a $30 repair, though you will want to set aside several hours and an uninterrupted workspace because it involves many tiny screws. You can find a replacement keyboard easily by searching on ebay for your model number. Hope this helps!
