Der Ruhezustand hat bei mir immer funktioniert. Habe es in den Systemeinstellungen so eingestellt, dass es nach 2 Stunden in den Ruhezustand wechselt. Morgens habe ich es dann mit dem Einschaltknopf geweckt.
Plötzlich funktionierte es nicht mehr. Jeden Morgen ist es immer noch aktiv. Ich habe versucht, im Menü „Suspend“ auszuwählen. Das System verhält sich, als würde es in den Ruhezustand wechseln, d. h. die Tastaturbeleuchtung geht aus, die Monitore gehen aus usw., aber dann fährt es sofort wieder hoch.

Antwort1
Dem Protokoll zufolge scheint das System ein Ereignis empfangen zu haben, das es sofort aus dem Ruhezustand geholt hat.
Haben Sie begonnen, neue USB-Geräte zu verwenden, beispielsweise eine neue Maus oder Tastatur?
Bei meinen Recherchen habe ich herausgefunden, dass es sich wahrscheinlich um ein Gerät handelt, das ein Wecksignal sendet, obwohl dies nicht vorgesehen ist.
