Faronics Power Save is an effective and reliable energy conservation tool that accurately manages energy consumption throughout ain a multiple workstation environment and significantly cuts down on energy expenditures. Power Save offers flexible options for determining when a computer is inactive (by CPU usage, hard drive usage or by running applications—not just keyboard and mouse movement), and only shuts computers down when they are inactive for a specified amount of time. As well, Power Save can schedule shutdown, start-up, and wake events by day, weekend, weekday, or a specific date. Faronics Power Save provides central reporting, configuration management, deployment, and control across an enterprise via Faronics Core Console. »
