My HTC 8X Won't Turn On And It Even Stopped Vibrating!

[WPCentral Question]

I had looked up ways to fix my htc 8x because it didnt turn back on and ive had it charged for hours thinking maybe it was because of the lack of charging time ive been giving it. And now it wont even vibrate to let me know I'm pressing the power button! And if I have to get it fixed at the Verizon store I'm scared of losing all my numbers and everything else.

Have you tried long pressing the power button for I'd say 15 seconds?
