Abstract

La présente invention se rapporte à un procédé et à un dispositif adaptés pour acquérir le temps consommé par un élément de démarrage. Le procédé selon l'invention consiste : à acquérir le temps consommé par un premier processus et le temps consommé par un second processus, le premier processus étant un processus qui correspond à l'élément de démarrage et le second processus étant un sous-processus du premier processus; à utiliser la somme du temps consommé par le premier processus et le temps consommé par le second processus en tant que le temps consommé par l'élément de démarrage; et à désactiver l'élément de démarrage lorsque le temps consommé par l'élément de démarrage est supérieur à un seuil prédéfini.
