Hi all, I'm new to this forum so I hope I'm posting this in the right place! My problem is this......I've had my Nexus 7 for 16 months and just started having this problem...it will not turn on. I was using my tablet a few days ago, it was around 70% charged, then went to bed and shut down my tablet. When I went to switch it back on the next day....nothing! I cannot even get the screen to show dead battery icon etc, just total blackness I looked it up online and it seems to be a common problem, and lots of people suggesting to do the long press holding down the power button for over 30secs, or holding the power and volume down button 30 secs....apparently it works for most people, I tried it a million times and it doesn't work for me , I tried following the troubleshooting steps on the google software tech support site, still no luck...tried connecting it to my laptop via usb, it says device not recognised. I even ended up ringing the google tech support and still could not fix this. The charger is the proper branded one that came with the tablet, and I know it works fine as it has been used to charge other items, also tried using 3 different plug sockets, but nope I'm getting nothing!! I know my warranty expired as it's over a year old, so want to try and avoid having to send for repairs etc. Please can anyone help as I am tearing my hair out here!???!!!
