How to opening a Vizio Tablet?

I was wondering if opening it is the came has the HP tablet? I dropped mine and one of the cornors sort of popped open. The one near the slot for the Micro SD card. I closed it back up but then a few days later noticed that my music files were missing. When checking the Micro SD card slot I saw that it was missing. I put another card in it to see if it would work. When I pushed it down waiting for that little click feeling it slid out of sight. It leaves me wondering if the card I had in there when I dropped it is also still in there. I would like to open up my tablet to check and see.
