Problems Booting Macbook Air

Recently my 2009 Macbook air will not boot. I used it about a week ago and have had no apparent problems. Tried to turn on yesterday and nothing- no fans, hdd kicking on, power to screen. Plugged in power cord thinking it was dead and the indicator displayed green, which I knew was incorrect. Still displaying green when I plug in charger. Sounds like it may be a mobo problem to me. Any helpful advice?

I live a little ways away from the nearest Apple store so I was hoping not to drive around 2 hours for someone to tell me there is nothing they could do.
