No lights on my asus U46E-RAL5 computer

Hello,

Last night was Watching a movie and my computer threw up the message that 10 % remaining on the battery, and I needed to plug it in. Well was going to plug it in and it went into hibernation mode then complete shut down. I have tried charging it, holding down the power button for over a minute, remove the power supply and battery pack and hold the power button down for 45 seconds then install the battery an power supply and try again. Nothing is working. Anyone can think of how to get it started. Also when I has the power supply plugged n the small light on the front of the computer doesn't come on. Anyone have some suggestion, please.
