Long time lurker, first time poster. I searched the forums and did not find this question asked previously, so I apologize if I missed it. I've had my iPad since Thursday. 2 times, I've hit the home button or power on button, and the iPad has not turned on. If I plug it in with the charger or hold down the power and home button, the iPad turns on. I dont notice any issues with the battery being at the same percentage when I turn it back on, this is more of "is this normal" type of question.....Why is the iPad failing to turn on using the Home button? Thanks!
