Thanks to Dan Frakes, Macworld.com, for reviewing Power Manager in Mac Gems.
Dan took the time to get to know Power Manager and his review picks up on some of the product's more subtle features: Power Manager's stricter definition of "inactivity" over Apple's "idle time" makes schedules easier to predict, and small touches like waking a sleeping Mac to ensure the scheduled event occurs on time.
This makes Power Manager especially useful in environments—classrooms, labs, a child’s computer—where you want to make sure your schedules are followed. If your Mac is asleep when an event such as a logout or shutdown is scheduled, Power Manager will even wake up the Mac to ensure the event occurs.
