Abstract

Un dispositif électronique, comprenant : un système principal ; et un système de détection qui est dans un état de mise sous tension normale et qui est pourvu d'un composant de détection et d'un composant de commande, le composant de détection étant au moins utilisé pour détecter si le dispositif électronique satisfait ou non une condition de démarrage du système principal ; et le composant de commande est au moins utilisé pour commander, en réponse au fait que le composant de détection détecte que le dispositif électronique satisfait la condition de démarrage du système principal, le système principal de façon à ce que celui-ci soit mis sous tension et entre dans un mode de veille. Sur la base du maintien de la complexité du système du dispositif électronique, des modes de réalisation de la présente invention peuvent encore atteindre le but de démarrer rapidement le dispositif électronique. De plus, selon la présente demande, avant de commander le système principal du dispositif électronique de façon à ce que celui-ci soit mis sous tension et entre dans le mode de veille, le système de détection du dispositif électronique peut être alimenté et détecte si le système principal doit être commandé de façon à être mis sous tension ; et par comparaison avec le système principal, le système de détection consomme moins d'énergie dans la condition que le système de détection et le système principal fonctionnent en même temps. Par conséquent, une perte de puissance excessive provoquée par une mise en veille à long terme du système principal peut être évitée.
