What is Wake-On-LAN?
Wake-On-LAN is a technology which allows administrators to remotely power on systems from sleep or standby modes. To use Wake-On-LAN technology on a PC, it must be supported by both the operating system and the system hardware. Wake-On-LAN technology is a result of the Intel-IBM Advanced Manageability Alliance.A Wake-On-LAN capable network adapter is able to draw power from the power supply when the system is switched off. The network adapter continuously monitors the network watching for a specific type of network packet called a Magic Packet. When it receives that packet it alerts the system to boot into a full power state.
