Can I somehow tell Vista to wake from sleep mode to run an application? I leave the PC connected 24/7 but want to use sleep mode for the long hours of no activity. I want to schedule my anti-virus software to scan around 02:00 when I am sure I will not be using it. The scans do not initiate because Vista is in sleep mode. Is there a setting, a script or something that can cause Vista to wakr up at a pre-set time?
