Disclosed is a method and system the equipment that can safely shutdown digital equipment. The system includes means to detect when the primary power from a mains supply (1) is lost, for example a voltage detector (6), and a secondary power source, such as a rechargeable battery (4) which has enough power to shut down the digital control of the equipment in safe fashion. Following that shutdown, the battery (4) is disconnected, for example by way of a relay (5). The system may have a voltage detector to monitor the condition of the battery, and report the condition, which may stored in memory and used to generate advice for the user to change the battery when required. The digital equipment may be coin operated leisure equipment, controlled by a computer with a hard drive and speakers.
