Last night I was on messenger with my tablet, when i just left it for 5 min. I came back and tried unlocking it till i saw it was off this already happend to me once but i pressed the power button for about 20 seconds and it turned on but this time ive tried everything: pressing power and down volume button, pressing power button and touching screen, charged it all night, plugged it on the computer ( though when i plugged it the computer detected the usb device, but the tablet still wouldn't turn on) I honestly have no idea what to do, the battery wasen't empty either. I've only had it for about 2 months and i use it alot i would really appreciate it if anyone could help me.
