Hi. I have a coby kyros mid7015 and the black power button won't work. I dropped it a few times... After the last dropped it stopped working. I used the rest button at the bottom of it every time it took a rest or when my internet was not working. I was on the internet before i left to go somewhere away from my internet connection. It was in the car on rest but i didn't use it for a day. I reset it the next day and now it won't work. ahhhh Please help. This is my first tablet.
