My suspicion is that the battery is flat and not taking a charge. If you have another micro-USB cable, try using that to make sure the plug isn't worn out. Sometimes the plugs will wear to the point where they will go in, but won't connect well enough to charge the device. Try letting it charge for ~8 hours and see what happens. If it still won't turn on, there is a problem with it that can't be fixed easily.
It looks like you may have disconnected. When you would like to continue our conversation, type a response in the box below and hit the reply button. I will be sent a message that you have reconnected and I will reconnect to you as soon as I can. Bear in mind that I am located in the United States (Central Time) and if you are in a different time zone, that may affect response times and availability.
