I have played with my Nexus 7 for about 8 hours. There was about 20 percent battery left and the tablet turned itself off. I tried plugging it in and letting it sit for a few minutes and no battery icon appeared. I have never turn it on yet and I think it is dead. Pressing the power button for 5 seconds and nothing shows up on the screen. I haven't rooted the device. Is there a way to fix the issues?
If the Nexus 7 won't turn on, you just have to hold down the power button for 30 seconds or more. it will power on again and that does the trick. You might hadn't held the button down long enough. It seems like a very comon issue on a "brand new" device. If not working, you'd better go to send a replacement.
