Macbook White Unibody retail

Product Name: Macbook White Unibody retail
I have a white macbook unibody that will not turn on for sale. The macbook power light turns on when it is plugged in but the macbook does not appear to ever turn on. The macbook is in used condition and has signs of ware. The bottom of the macbook has rubber that is wavy. The macbook was purchased in a lot and I am ot sure what all could be wrong with it retail so it is being sold as is no returns buy at your own risk. The default item description may be wrong so what you see in the pictures is what you will get.
