And now NOTHING!

I had been moving apps to the SD card then NOTHING. Everything went black. No power no nothing. I have tried to charge it. (It was already charged). But now it won't charge or anything now. I love my tablet & hate not having it. Plus, I have a few things I need to get off the device!!
