what do the various USB charge while sleeping modes mean? my new laptop has these sleep while charging modes :

mode 4
mode 3
mode 2
mode 1

the list box doesn't tell me what these modes mean or do. I noticed that my iphone is charging really slowly on mode 4. What is it going to do to my power consumption if I change it to something like 1 or 2 ?
