hi,<br style="font-family: Arial, sans-serif; font-weight: bold; line-height: 15px; ">I bought the commtiva n700 for my mom and now she is very frustrated since the device will no longer turn on. I believe she turned it off to save some battery then when she turned it back on there was just a vibration coming from the unit as if it was already about to turn on but to no avail it wouldn’t power up. My mom assumed it was just drained so she charged it in the main supply for several hours now say running 8 hours but still it wouldn’t turn on. I mean normally this unit would turn on even if it is charging. we can only see a red light in the led indicator and by the way we’ve been trying several main power supplies hoping it would help but we are of no luck! please please help this is my mother’s first tablet. I didn’t imagine it would give up just after 2 days usage. I am not even sure if you can still read this post guys since this was dated like years ago but I was wondering if you found a solution for it.
