[W7x64] Krijg pc niet in Sleep mode

[henk99]

Ik ben nu al enkele dagen bezig met het instellen en testen van mijn pc om hem in slaap te krijgen na 45 minuten geen gebruik.
Ik kan hem prima in slaap krijgen met de sleep-knop op mijn keyboard, maar automatisch na 45 minuten wil niet lukken.
Ik heb een aantal dingen geprobeerd, waaronder een aantal powercfg commando's zoals:
powercfg -energy en powercfg -requests
Bij de eerste krijg ik een rapport van de analyse waarin een aantal errors staan. Ze hebben bijna allemaal samenhang met USB achtige zaken. Ik kan er alleen niet achter komen wat ik nu verder moet doen om het op te lossen.
Hieronder een deel van het gegenreerde rapport:
