unresponsive dv6000

I have a hp dv6000 laptop that is about 2 years old. Today when i went to turn it on, i noticed that the light that indicates that a power cord is connected was off and that the computer wouldnt even attempt to boot. I know i just bought a new powercord off of ebay a month or so ago, and was wondering if this could have fried my components, if this is unlikely, what would be another possible cause.
thanks
james
