iPad Air unresponsive with a black screen

My ipad air is completely unresponsive. Basically a black screen. Siri works though, but not anymore.

I've tried many ways to fix it, from tapping a specific area to preforming a hard reset and restoring it.

Nada. Nothing at all.

It has 100% charge, I know that because of iTunes.

More info: It worked fine until I dropped it sideways but it fell from a low couch to a carpet? no cracks or physical damage.

Please help because I'm traveling in a few hours and I've tried almost everything.
