IPhone 4s will not turn on or hard reset?

Question

iPhone turned itself off? Won't turn back on? Hard reset not working? Keep reading...
When this happens, your iPhone is stuck in sleep mode. Normally, you can alleviate the problem by doing a hard reset, but in this case nothing works. This problem can spring up from time to time even if your phone has a decent amount of battery life left. There could be any number of reasons your phone keeps getting stuck in sleep mode, but these are my speculations: a) overheating, b) overexposure to moisture/high humidty, c) software overload/app crashes, or d) phone storage at or near capacity.
You realize that the normal fixes aren't going to work, so here's how to fix it:
1. Place phone in ziploc bag in freezer for ~15 minutes.
2. Place phone in bag of dry rice for ~30 minutes.
3. Use another phone to call your phone (you'll notice you still hear a ringback as if your phone is on). Keep calling. After each call, try to turn your phone on using the reset method or simply using the lock button.
After several calls (or one if you're lucky), your phone should either turn on, or tell you to hook it up to a charger. Hook it up to iTunes just to be safe. If you're still seeing a dead, black screen, take it to the Apple store

Usually a reset will help. Hold the sleep/wake and home buttons together until you see the Apple logo and then release. This can take up to 20 seconds if the device is unresponsive.
