		Just posting this solution to possibly help others.
For years my HTPC wakes up in the middle of the night for the EPG update. Recently (after a Windows update?) it would still be awake in the morning despite no active power requests. Logging in to check or just moving the mouse with the TV still off would allow it to sleep again. I then remembered that Martin had taught me about "System Unattended Sleep Timeout" here and setting the desired timeout there fixed this problem.
How to Change System Unattended Sleep Timeout in Windows
P.S.
Go Blue Jays, just one more win!
