Sleep mode refers to a low power mode for electronic devices such as computers, televisions, and remote controlled devices. These modes save significant electrical consumption compared to leaving a device fully on and idle, but allow the user to avoid having to reset programming codes or wait for a machine to reboot. Many devices signify this power mode by a pulsing LED power light.
In computers, entering a sleep state roughly equals to "pausing" the state of the machine. When restored, the operation continues from the same point, having the same applications and files open.
Sleep mode can go by many different names, including Stand By (for Microsoft Windows 98-Server 2003), Sleep (for Mac OS 8-Mac OS X, Windows Vista, Windows 7, Windows Server 2008), and Suspend (Windows 95, Linux). When placed in this sleep mode, aside from the RAM, which is required to restore the machine's state, the computer attempts to cut power to all unneeded parts of the machine. Because of the large power savings, most laptops automatically enter this mode when the computer is running on batteries and the lid is closed. If however undesired, this behavior can be reconfigured in the operating system settings.
