Last night tablet wouldn't turn on. Locked itself into the start up screen. The buttons seem to work and when I tried a hard reset - and it will give me the tiny notice at that top that I'm asking for a cold boot, it doesn't go into it. I tried accessing via pc/phone too. BUt if it's not on, it doesn't show up. I read another thread about borrowing a ROM from my phone but I have a GNex and there's not finding any of the good stuff without rooting, which I don't do. so I've tried the hard reset I've tried accessing via pc my tablet is not rooted and overall it's been working fine. No issues. Then suddenly this. Why does this stuff happen? it's seems crazy to me...it's just about a year old and it's acting up. I'm not sure what to do now. Call ASUS? Send it in? Should I send in keypad and power source? Please Help. Thanks in advance.
