An apparatus and method for extending the supply of reserved power during an interruption to power supplied by a primary power supply in an in-flight entertainment system is disclosed. The apparatus has a power supply that provides a first supply voltage and a capacitor coupled to the power supply that stores a second supply voltage. The apparatus further has a detector circuit that generates a first signal upon detection of an interruption in the first supply voltage. A control circuit coupled to the detector circuit, the capacitor and the power supply, generates a second signal in response to the first signal. A processing circuit coupled to the power supply, the capacitor and the control circuit, disables its operation in response to the second signal. The capacitor provides the second supply voltage to the control circuit in response to the interruption.
