Unable to shut down completely. some hardware is persistently stays on
I am aware that this problem is not unique, and read dozens of posts on this forum, on Microsoft forums, and on the web before posting this.
This is a new Windows 7 Pro SP1 installation of two weeks ago, and am unable to shut down completely. At installation it worked fine and then one of the Microsoft updates messed it up and don't know how to correct it. Have been working on this problem for the past ten days, on and off but without success, so I am posting this with all the pertinent info.
What is happening is that at shutdown, the fan (only one is installed), the shut down button, and the USB hub & ports remain alive. The PSU is off.
This is definitely a Windows 7 problem because I also use Linux Xubuntu 14.04 and this shuts down without problems.
Hardware:
Starting with the motherboard BIOS, all settings are at default, with the exception of disabling the 3.5 floppy drive, and the boot on logo. Please see the three uploaded images for the BIOS default power settings.
Software:
1. Set Windows power options to 'balanced' default but disabled computer sleep and monitor shutdown.
2. Unchecked all power management settings in device manager. This includes all (11) HID compliant devices, IEEE 1394 Bus Host controller, (DWA-130 USB Wifi dongle) Wireless Microsoft 800 Keyboard, Logitech Mouse, and all (7) USB Root Hubs.
3. No errors in the Event Viewer, except a warning about WLAN shutting down successfully.
4. No driverless hardware in the Device manager, everything functions.
Perhaps someone can suggest some additional possibilities?
