Reduce your environmental footprint. Power on your systems when they are needed.
Ask your staff to put their desktops into sleep state when they go home for the evening, and have netPrefect™ wake them up automatically in the morning before they arrive for work.
We all win, the environment is better protected, you save on utility bills, and as a bonus, you don't lose worktime as your PCs are already powered up when the employees get to their desk in the mornings. What could be better?
