Sleep mode (or suspend to RAM) is a low power mode for electronic devices such as computers, televisions, and remote controlled devices. These modes save significantly on electrical consumption compared to leaving a device fully on and, upon resume, allow the user to avoid having to reissue instructions or to wait for a machine to boot .
The method by which a sleep proxy server wakes a sleeping host is wake-on-LAN. The network interface of a sleeping host with this capability will wake the machine when it receives a specific series of bits, and a packet containing this pattern is a magic packet. Early implementations of Wake on LAN (WoL) required

DevSlp or DevSleep (sometimes referred to as device sleep or SATA DEVSLP) is a feature in some SATA devices which allows them to go into a low power "device sleep" mode when sent the appropriate signal, which uses one or two orders of magnitude less power than a traditional idle (about 5 mW, [1] but some drives can get as low as 2.5 mW [2]).
