What kind of noise? Is it the normal, happy "bong" sound? The chimes of death? A horrid noise that sounds like two bricks grinding against eachother?

As for the "nothing", does:

1. The screen come on in any way, shape, or form?

2. The drive (assuming there is one) spin up?

3. Does the internal fan turn on?

4. Or does it just sit there as though you hadn't turned it on at all?

These will go a long way to helping us help you
