On a long trip home, I sat on my Asus Tablet for around an hour (Idk why I'm dumb...) while I was asleep. When I woke up I tried turning it on, but it didn't work. I charged it for 3 hours, tried to turn it on, but it didnt work. I held the power button for 30+ seconds and tried turning it on, but it didnt work. It doesn't have a removable battery. Also, if I use the volume keys, I hear the sound it makes when showing how loud notifications will be. Please help?
