Tablet wont respond in any manner?

I have a Samsung Tablet 3 10.1, GTP5210ZWYXAR.

The tablet worked perfectly up until last night, now it wont turn on, I attempted to charge it over night, nothing. Holding the power button doesn't work, holding the power and volumes doesn't work, there is no display of charging sign when plugged in and I have tried 4 charging cables and three wall plugs. I attempted to connect to my computer, nothing, it wont recognize the device at all, nothing is happening, the tablet is brand new and has been flawless.. someone help me please...
