A recent survey of hundreds of professionals found that their desktops remain powered on during 43% of total non-work hours, including evenings and weekends --- meaning that computers are operating yet unused for more than 55 hours a week in LAN. Worse, each respondent's computer was almost certainly equipped with power management settings -- energy-saving features that went unused. This equates to an unnecessary, additional electricity cost of more than Rs 1000 per medium capability desktop annually. It would save approximately 15 million megawatt hours, enough electricity to light 8 million homes. It would also prevent six million tons of greenhouse gas (CO2) emissions, roughly equivalent to removing a million cars from the road. Networks pose special challenges for power management. Depending on the systems (hardware and software), the network can partially or entirely defeat power management, or may require extra configuration changes for it to function. Now a day's many LAN have heterogeneous environment in which different operating systems are running on client side such as Microsoft windows and Linux based OS, generally windows on client side and Linux based system on server side. Microsoft dispatches the power management patches for the LAN which has only Microsoft client and server. So third party solution is required for the power management in LAN which can be used in such heterogeneous environment. Some software solutions are available that you need to be purchased and to pay for maintenance which discourages people to install it in their LAN. Hence to solve this problem a software system has to build that can serve us to achieve all this needs and will be freely available to all. Problem Definition: Our aim is to write such software that can be used as a remote control for PCs connected as a Local Area Network, this software can be used to identify idle machine in network and put them in standby mode remotely. We will have utility application which needs to be installed on every client its job is to set power scheme and when user will become idle it will ping to the server that gives current information that system is going to standby mode.
