1. A power providing device for providing power to a plurality of power receiving devices, comprising:
a power distribution unit including switches to forward operation power received from an external power source or standby power received from a standby power source, the standby power being lower than the operation power, to one or more power receiving devices,
a processor to control the switching between an ON-state and an OFF-state during an operation mode when operation power is received, and to monitor power forwarded during a standby mode when standby power is received, by sampling said power at a periodic rate, and adjust the periodic rate using an adaptive sampling technique, wherein when a difference in current samples is higher than a predetermined threshold time between samples is reduced,
wherein the processor controls switching to the ON-state when an increase of the power forwarded detected over a predetermined monitoring period exceeds a predetermined detection threshold, thus switching from the standby mode to the operation mode.
