Pour tout les CPU de la machine. Ca a fait ça pendant environ 25 mins, donc machine “down” à 8h25, mais elle était juste en “standby” j’ai l’impression, puisque toujours allumé, mais écran noir etc etc …
J’ai essayé de me documenté là dessus, mais j’ai pas encore trouvé grand chose, enfin j’arrive pas à définir si c’est matériel ou logiciel, et je coince assez là dessus ><
Si quelqu’un à une idée là dessus, ça serait sympas ! :d
Bonne journée
