It updated over wi-fi at home, I then charged it from a battery pack as it was on about five percent battery.I turned it on later in the day at work and it started up then screen went blank with the three dots. Since then the power led flashes on pressing to start then stays on constant, when it's plugged in it does the same, no change in screen, it doesn't light up or anything.I have read some of the threads and held down the power button for various lengths of time, left it charging overnight and still no response from it, the led light coming on is all that happens.
Jim.
