Sleep Mode on Timer Different Than Manually Putting System to Sleep?

Bottom line up front, my computer produces different results in sleep mode, depending on if I initiate putting the system to sleep versus following the configured power plan.

1. When I manually put the computer to sleep (Start > Power > Sleep), I can observe that my display shuts off immediately and all case/cpu fans, LED's, and peripheral USB devices shut off within about 10 seconds. This is my expected result.
2. When I let me computer go to sleep after idling for 5 minutes (advanced power settings listed below) based on the power settings, I observe that my display shuts off immediately, but NONE of my case/cpu fans, LEDs, or peripheral USB devices shut off, regardless of time passed. Even an hour later, all these devices remain powered. This is not my expected result.

What needs to be configured to allow Windows to sleep with the same desired result as manually selecting the option in the Start menu?
