10.10 Yosemite Mise en veille partielle iMac sous Yosemite

[bjsc]

Bonjour,

Depuis 2 jours mon iMac ne se met plus complètement en veille. L'écran est noir, les disques durs ne tournent plus mais la souris et les voyants des disques durs externes restent allumés.
Redémarrage, redémarrage en mode sans échec et réparation des permissions n'ont rien donné.

J'ai exécuté plusieurs commandes dans le Terminal et le problème semble venir d'Address Book. Voici les résultats :
avec la commande ""pmset -g" :

Quelqu'un aurait une piste pour régler le problème ? Merci pour votre aide./
