    New win8 installation wont automatically sleep


    I have an HTPC that previously had Windows 7 installed. I have it setup to sleep automatically after 3 hours in case we accidentally leave it on. I did a Win8 Pro upgrade on top of it, and it ported all of my apps and settings fine.

    However, no matter what I do, it won't seem to go to sleep automatically. It works perfectly fine when I do it manually. I've gone into desktop mode and verified nothing is running (nothing open on the taskbar, at least). There is no video app or anything still running that would block sleep.

    How can I properly debug what may be blocking it from sleeping? Could it be some glitch where it thinks it's setup to sleep in the power options but in reality it's not?

    You don't mention what the sleep settings are set for.

    What power profile are you using?

    Apologize, it's setup for balanced power and I went and changed 'sleep' to 3 hours. I went into the advanced settings and saw there was an option to block sleep if it's sharing media. The machine only pulls media from my main desktop, it doesn't actively share with other devices (nothing streams from it). However I just went and disabled that option in case that might have been the cause.

    There are other things, like USB and PCI devices that can prevent sleeping as well. There are settings in the power profile to control that. You might want to just go through all the settings and see if anything stands out.

Solved Computer Wont sleep in Performance & Maintenance
Hi, After updating from Windows 8 to Windows 8.1 my PC doesn't seem to want to sleep. I've done some googling and cant really find anything. I found a command prompt thing I should do. I did that and it said nothing was keeping my computer awake. Any advice or ideas? Thanks, Mitch
It's a temptation to install and explore 8.1, but siding on the side of caution and prefer to delay the upgrade. The 8.1 upgrade is NOT automatic, is it? I would like to wait, maybe a month, for all the kinks and bugs to get worked out of 8.1 before it's installed on my PC. Using a...
