I got my tablet two weeks ago (for Christmas) I was doing some note taking and had it sitting on a table, untouched for a few minutes, when it told me to plug in the charger. A minute later, the screen just blacked out. It won't turn back on. There's a popping sound from the back when it tries to boot up. I put it on charge, but the charging screen isn't coming on either. I've even tried rebooting it, but it just does the same thing. Absolutely nothing. Any idea what it could be?
