Hiya, I'm having an issue with my daughters Cnm 7. She brought it to me this evening and its not responding what so ever, nor is my laptop recognizing it as an external device when plugged in. Was working fine this morning, barely 2 months old and left on charge while she was at school. It hasn't been dropped or knocked and is well looked after. I have held the on button for over a minute...both unplugged and on the mains. I have tried Vol + (and - as a google search yielded various results) in conjunction with the power on (both on the mains and unplugged). The OH used his multi meter to check the charger...current is running through both charger and tablet whilst plugged in... (this one was a just because we were ruling out EVERYTHING!) It is for lack of a better word....dead No vibrate, no flicker, sound or response.. I'm a complete Tablet noob and at a lost....any further advice on attempting to get it too work would be great, was only working just over 10 hours ago Regards.
