    Not sure why this is happening - I think it might be related to either my new dual monitor setup, or the fact that one of them is a touch screen.

    Basically, I used to be able to browse to the Start menu and select "Sleep" and have my PC go to sleep (ie. save energy) when I was done working at the end of the day. The next morning, I could wake it and would be up and running in seconds.

    Now as soon as it enters sleep it automatically wakes itself up again. I haven't touched a key or mouse or anything. I'm thinking maybe it's related to the touch monitor? I really can't figure it out and it's driving me crazy because I don't want to have to completely power down and then wait for my PC to power itself back up again.

    They key is figuring out what device is awaking your PC. In most cases, the culprit is your mouse or keyboard. We plugged a USB mouse in the front USB port of a Windows 7 PC once, and experienced the same exact issue - it would automatically awake Windows from sleep the second it entered it.

    To find out what applications are set to awake your PC from sleep, browse to the command prompt at Start Menu > type "cmd.exe" > Type powercfg -devicequery wake_armed

    The output on ours is:
    Standard PS/2 Keyboard
    Logitech USB Wheel Mouse (007)

    We found out the mouse was awakening our PC from sleep by turning off its power management capability via Device Manager. Browse to Start Menu > type "Device Manager"

    Browse to "Mice and other pointing devices" > expand the menu > right-click on your mouse entry ("Logitech USB Wheel Mouse" in our case) and select "Properties." Select the "Power Management" tab, and uncheck "Allow this device to wake the computer."

    Try this for any device reported with "powercfg", or any device you can think of that might be used to wake your PC.

    The quickest way to see if this approach is effective is to disable the awake function for all of them, put your PC to sleep, and see if it stays asleep. You can hit your PC's power button to re-awaken it.

    Hope this helps!

    You can also browse to Start Menu > Control Panel > Power Management and see what kind of settings are in place and if your PC is setup to go to sleep in the first place. Under "Advanced power settings" you could try, for example, to adjust the "multimedia settings” option. Browse to "when sharing media" > "allow the computer to sleep."
