Hi. I've been using windows 7 ultimate for almost 3 months now without any problems. However, a new issue has recently cropped up over the last three days (or so it seems). Essentially, my PC will S3 sleep when told to sleep manually, but will never idle to sleep.

I've checked power settings for USB devices, network cards, audio cards, turned off all sidebar programs, turned off every program I have running in the background, and pretty much every trick I could think of, but none of them work (including the infamous media sharing "allow to sleep" option). I'm very much convinced its a bug as the only recent change has been going from the default aero theme to a custom one with a slideshow wallpaper. As soon as I made that switch, I haven't been able to idle to sleep.

Again, windows 7 has no problem sleeping with a manual command, but never sleeps when idle. The monitor does indeed go black at the appropriate time.

Welcome to Seven Forums!

Perhaps a recent Windows update or new software install caused this? Also, please fill in your system specs when you have a chance.

I'm sorry to hear about your issue. Did you recently make any changes to your computer? A hardware device might be keeping your computer awake.

Hey Sunburn74, I responded to your problem in my thread on this topic, and have come to the conclusion that this is indeed a bug in Windows 7.

Windows 7 will simply not go to sleep on idle unless you use a standard Aero theme as a background. As soon as you change to a solid color background or custom background, sleep will not trigger when the computer is idle. It will continue to work with a manual click of the sleep button, but won't sleep when you walk away from your computer.
