I have two systems running Windows 7. One is a DVR that primarily runs Media Center. It has two HDTV tuners and 1 gig network connection to the other system. This system is my main system but occasionally I use it to record programs with Media Center when I need a third HDTV tuner.
I have noticed that quite often the main system is on when I check it first thing in the morning. This seems odd because I would assume an idle system should drop back into standby even if it does wakeup. I am wondering if this is really a network activity issue. I have configured the main system to stay awake while streaming. This seems like a useful feature but now that the DVR is configured, I won't be streaming that often.
Does anyone have suggestions for ways to really find out what is waking up my system unexpectedly? My next test will involve just unplugging the 1 gig network connection. That will make life inconvenient for a few days but it might be a valuable test.
