What do you think would cause a phone that is on a charger and has 80 percent battery to shutdown? But is also not powering back up at all; I mean I press the power button and hold it for a second or two, and I get nothing. No light on screen, no vibration to let me know that there is power I mean I get no response from the phone at all. Would like to know what you think is the problem?
Is this a good question?

Try another battery. If it's still no good then I think it's no good.
