For some reason my computer won't sleep. I press sleep button on keyboard, it goes through the motions of entering sleep mode. As soon as power goes "off" it wakes back up. Does the same thing using sleep through the start menu. This is a pretty recent issue, can't recall the computer doing this before about a week ago. Just noticed when I returned to the room one day that it wasn't "sleeping". Only thing that I changed recently was to install Windows 10 in dual boot with existing installation of Windows 7. I kept Windows 7 as default OS and haven't touched 10 since I did the installation and activation. Problem is occurring from within Windows 7. Haven't attempted to replicate from within 10 yet, but I'll do that next and report results. I do not recall messing with any settings recently that would have affected the sleep state. In attempting to remedy the issue I reset all power settings to default, even though I don't recall changing any to begin with. I checked through my devices and the only ones set to wake computer are keyboard and mouse. Hardware is: ASUS P8Z68-V Pro/Gen3 Intel Core i7-2600K W/ Antec KUHLER H2O 650 CORSAIR Vengeance 16GB DDR3 1600 EVGA GeForce GTX 980 Ti 06G-P4-4993-KR LG BD-RW WD Blue 1TB 7200rpm SATA 6Gb/s Any suggestions appreciated... EDIT: Just tried Windows 10 and had no issues in sleep mode. So it's seems to be something to do with the Windows 7 installation only. Guess I'll just have to start powering down when I leave for work until I get this figured.
