I just had this happen to me today, my iPad 3gen was on charge and when I removed it from charge it completely is unresponsive to anything. Tried the home and sleep/wake button reset, still nothing held it down for 5 min and still nothing. Hooked it up to my computer and my computer doesn't even see that the iPad is connected. I've had this since the 3rd generation was released and just now having any kind of problem.
