Nexus 7 blank screen After watching a bit of 4oD last night on my Nexus 7, I turned it off. When I tried to start it up this morning, I was greeted with a blank screen whilst being plugged into the charger. I held down the power button, and Google flashed onto the screen for about 3 secs. When I disconnected from the charger, the screen switched off completely. 

I have only had this for a week and a half. It is obviously still under warranty. Can I just send it back? I am completely dumb when it comes to computer issues!
The same thing had happened to my N7. Here's what worked for me.

Let your device stay in that state for as long as the battery lasts, i.e wait till the battery is dead.

After that is done, Power on the devise by Holding the two volume buttons and then connect the charger or connect to a computer.

Use your volume buttons to navigate to START and click on the power button

That should bring it back to life

Edit Here is a photo of the boot loader I found on Google which shows the Start
