Abstract
A power saving apparatus that uses a plurality of switches, including a switch provided in a remote controller receptacle mounted on a device, to turn on or off power to a device according to whether a remote controller is received in the remote controller receptacle, thereby saving standby power of the device. The power saving apparatus includes first, second, and third switches, and a controller. The first switch is used to power on/off the device. The second switch is provided in the remote controller receptacle to turn on/off power to the device according to whether or not a remote controller is received in the remote controller receptacle. The controller outputs a control signal to turn on/off power to the device when power is supplied through the first or second switch. The third switch turns on or off the power to the device according to the control signal output from the controller.
