Hey guys, I just decided to set my computer to idle sleep but it wasn't working so I went into the command prompt and typed "powercfg -energy" and it told me I had errors regarding the energy settings, so I checked out the log and what I found was that all the errors were because the USB devices could not power down So I decided to unplug a few usb cables + my memory card reader (from the MOBO) and tested again, now telling me I had 3 errors... I gather that these would be the 2 front powered USB ports on my tower and my wireless mouse/keyboard (1 usb cable). So the motherboard USB devices are failing to power down when the idle-sleep tries to initialize. My motherboard drivers (And all drivers) are updated. Specs: CPU: Intel - Core i7 2600k @ 3.4GHz RAM: 8GB Dual Channel 1300MHz GPU: Nvidia GeForce GTX 580 1536MB (Gigabyte) MOBO: Intel DP67BA - LGA1155 (P67 chipset) HDD's: 2 x 1TB Western Digital Caviar Black SSD: Corsair Force GT 120GB (SATA3) Optical Drive: LG - GH22NS70 OS: Windows 7 Enterprise 64bit Case: CoolerMaster HAF X RC-942 Monitor: Benq G2450H 24" All I can gather is that the MOBO doesn't support it (Cheap mobo but efficient). I am able to put the computer into sleep manually without any issues.
