Dead Nexus 7 - No! Just Sleeping

I really love my new Nexus tablet. The speed and beauty is wonderful. You can imagine my dismay when I went to turn it on for the first time in the day and nothing happened. I worked the power button over and no response. I plugged in the charger. Nothing. I plugged it into a USB port, nothing. I was really beginning to panic. So i googled dead Nexus 7 and I was not the only one to have this experience. The solution was to hold the power button down for a long time. Anywhere from 15 to 40 secs. And to my delight, the tablet came back to life after about 20 secs. It hasn't happened again, and hopefully it won't. What a relief to get it going again and to avoid the hassle of a return.
