Standby mode is one of several operating states of personalcomputers, notebooks, tablet PCs and also consumer devices such as TVs or DVD players.
It is a standby mode in which certain device components and device functions are still active, while others are switched off. Other modes include sleep mode, sleep mode, and hibernation with power-down operation.
In standby mode, the device waits for a command with which the previously used functions and programs are reactivated without a long wait. Classic electrical devices have a current consumption of a few milliamps (mA) in standby mode. With energy-saving components, such as those used in battery-free sensor networks, the standby current is a few micro-amps (µA) and in the case of EnOcean even less than 1 µA.
