Since I've installed ZENWorks in one of our Mac labs the workstations will not go into sleep mode. It looks like Zicon is constantly doing something in the background and keeping them awake. The screens will turn off after 15 minutes, but sleep mode for the CPU and the disks never get going.

I'm not big on wasting all of this energy, not to mention the pure amount of heat generated in the lab with every workstation turned on and going all day and night. Anyone else have this issue? What can I do?
