Black screen and no response

[AC Question]

I just got this HTC One M8 less than a month ago, and have loved it the entire time. This is the first problem i've had with it. Earlier today, i was sitting down eating while using the phone. I looked down to take a bite, and look up to a black screen. the phone was at ~80% battery, so i know it couldnt be dead. i touched it and got a vibration, but after that, nothing. I've had it plugged in for maybe the last half hour now, and in not to sure what to do at this point besides take it to the AT&T store.

If not, then I agree, take it to the store, or contact HTC.
