What is connected standby?
Connected Standby is a device operating mode for Windows in which a device can remain in a power-saving hibernation state, but can still immediately switch to a fully functional state.
Connected Standby enables a processor operated with Windows-on-ARM (WOA) to have minimal battery power when it is not in use and / or its display is switched off.
The connected standby mode is primarily the battery operating mode of a device on the Windows operating system. In this mode the device is switched on, but the display is dark. Windows interrupts any applications that may be running and puts the device in a state that uses minimal power for users. When a user issues a key or touches the screen, the device is immediately ready for use.
Connected standby differs from sleep mode in that it can immediately switch between an offscreen standby mode and an on-screen online mode.
