How does sleep really work in the Android kernel?

I've been wondering about this for a while, but couldn't find anything about it. What exactly happens after the screen turns off? Does the kernel actually suspend and halt the CPU? If so, how are notifications received while sleeping? Is there a coprocessor involved?

I'm curious. It would be great if someone could point me towards some articles or videos about this.
