speakers

I guess all of you have a pair/set of speakers for your MP3s. I am just interesting to how do they do when they are not playing?

How actually the power spent by the speaker? Does any the below cases matter?

Idle / Silence input
When you computer is off / not connected
Raise the volume by hardware (turn/push the button on the speaker)
Raise the volume by software (do it with your mouse)

BTW, to save the world. I am here to suggest you to unplug it when you leave your PC.
