It may be a problem with the motherboard or screen. Have you checked out the troubleshooting page from Ifixit?

I would check the battery using this gem of an app CoconutBattery post a snapshot of the apps main window.

Also check the onboard battery checker on the side how many LEDs do you see and are they blinking?
