I did charge it at night before sleeping and by 6 AM I woke up and get my tablet and then it did not turn on. What happened?
I had this problem once, a few weeks ago. Pressing on and volume + or - didn’t work. No heat detected while charging. I opened the asus, disconnected then reconnected the battery(found the procedure on youtube): the asus started and showed battery symbol near zero. I charged it immediately and fully, then assembled it. It worked.
