Laptop will not power on

Hello,

I have a Dell Studio 1535 laptop and it will not power on. I push the power button and nothing happens. When I plug the power adapter in the charging light will come on for ~1 sec and then turn off. If I take out the battery and put it back in while the charger is connected, the charging light will flash from white to red then white again. I don't know what is going on. Does anybody have any idea? Thank you.
