Pour visualiser la consommation électrique, tu lances powertop et c'est vers le haut que c'est écrit.
En fin de compte, ça ne marche peut être pas si bien que ça. Je dois vérifier que la carte graphique Nvidia est désactivée, que la carte graphique integrée Intel fonctionne.
Voici un problème que j'ai :

Le module BBSWITCH n'a pas l'air de fonctionner et à mon avis la carte graphique est toujours en fonctionnement !
Une piste possible est le lien ci-contre mais ça n'est pas particulièrement pour Fedora :
