An apparatus 10 for remotely awakening an electronic device comprises power supply means 12 to supply external power; a receiver 38, 14 for an electromagnetic signal; a capacitor 18 connected to said receiver; a switching circuit 20 connected to said capacitor and a controller 22, being part of said electronic device, connected to receive power from said switching circuit and to provide a keep awake signal 24 to said switching circuit. Said switching circuit comprises connection means to connect said controller with said capacitor when said capacitor is loaded with a predefined amount of power via said receiver as well as switching means 40 responsive to said keep awake signal to disconnect said controller from said capacitor and to connect said controller with said power supply means afterwards. Herein said controller performs an initialization phase in response to first receiving power and enables said keep awake signal after completing said initialization phase. |
