There are a few things to check.
 
1) Is it under warranty, assuming it isn't because you are here but have to check.
 
2) Try turning it on by bypassing the power button, the question here has instructions on how to accomplish this. https://www.ifixit.com/Answers/View/99363/Where+is+the+power+jumper+on+the+logic+board *edit* (Check here for your model and where the pads are located) http://www.insidemylaptop.com/turn-on-macbook-pro-laptop-without-power-button-locating-power-on-pads/

The initial hard shutdown is interesting if the power button has issues maybe it triggered a hard shutdown and won't work to turn it back on.
 
3a) If bypassing the power button didn't work take a look at the magsafe board([guide|10371]) and inspect it for visual damage, also check your battery for swelling and see if it has charge(battery indicator button). Also does the power adapter have an LED light when plugged into the computer? If not the magsafe board might need to be replaced.
 
3b) If the bypass does work congrats, the computer is still working. Try reseating the keyboard cables on the logic board then try turning it on normally.(cables shown in steps 11-12 of this guide [guide|10369])
