My Acer tablet is dead too after using it only less than a year. I contacted the makers and they told me “there is nothing wrong with your tablet, you just forgot to power it” and gave it back to me. Not true, I kept it charged it and still today it woke up dead. (the makers didn’t teach me how they turn on the tablet) Some seconds ago I read about the “press power and volume up at the same time”. I did it and a black settings screen appear and I managed to reboot the tablet. It is working now (I don’t know until when). The makers don’t know their own product!

my iconia 7 notifications make no sound. The notification volume is at max. I have heard some notifications with sound, but when I put one appli that I build does not give any sound. Help please
