Abstract

UN SISTEMA DE ORDENADORES ALIMENTADO POR BATERIAS (C) CONTROLA EL BUS DE DIRECCION (20) PARA DETERMINAR SI A DETERMINADOS DISPOSITIVOS PERIFERICOS NO SE HA ACCEDIDO DURANTE UNA CANTIDAD DE TIEMPO PREESTABLECIDA. CUANDO LA CANTIDAD DE TIEMPO PREESTABLECIDA HAYA PASADO EL SISTEMA SE DESCONECTA POR SI SOLO Y DETIENE EL RELOJ DEL SISTEMA, COLOCANDOLO EN MODO DE ESPERA. EL SISTEMA SE REACTIVA PRESIONANDO UN CONMUTADOR DE ESPERA, A MENOS QUE NO HAYA SUFICIENTE ENERGIA EN LAS BATERIAS, CIRCUNSTANCIAS EN LAS QUE LA CORRIENTE AC SE DEBE CONECTAR ANTES DE QUE EL SISTEMA SEA REACTIVADO.
