Why wont my phone turn on? (LG Motion)

AC Question

Yesterday my phone worked perfectly till it died. I went to put it on the charger and only thing on was the 3 front lights. They weren't blinking at all, just a solid light. I held the power button down for about a good 30-40 seconds and it still doesn't work. I even took out the battery while the phone was still connected to the charger. The front lights were still on. Does anyone have any help??? Thank you!
