Why won't my HTC phone turn on?

[AC Question]

I went to work and turned my phone off and put it in my locker. Throughout the night it was on for maybe five minutes before going home. I tried to turn it back on and I get nothing. I checked websites and followed all the steps to try to get it to turn back on but even my computer will not register that its plugged in. what's up with this???

Have you tried holding Power and Volume Up+Down for a minute or two?
