sleep

My Windows 7 PC is set to automatically enter standby ("sleep mode") after 30 minutes. For some reason it stopped working a few days ago (it keeps on running). Is there some systematic way to determine what is preventing the system from automatically entering sleep mode after the designated idle time?

Manually sending the machine to sleep works fine. The monitor also enters power save mode automatically, so the "idling detection" of Windows seems to work fine.
