Windows 7: Motherboard preventing manual sleep

04 Aug 2011   #1

Motherboard preventing manual sleep

I posted a thread a while ago, and I thought something was preventing my computer from sleeping (Mouse or keyboard), but I have tried the lastwake command and it will say my keyboard at first, but keeps coming up with something else that awakened it my computer from sleep (As I disable all the things preventing sleep from device manager).
I was talking to my mouse' manufacturer support and apparently it's a setting in allot of motherboards that do not turn off USB devices after the system is shut down.
The thing I don't understand is, I have my computer set to sleep whenever it's left idle for something like 30-60 minutes, and it sleeps without waking straight after. It's just if I click 'Sleep' from the start menu, it won't do it .
I have looked around in my Asus M4A89GTD PRO BIOS but can't find it, I tried disabling some things but didn't do as I wanted. At this point I don't know if it's my motherboard or if it is indeed a USB device.

In device manager, under Univerisal Bus controllers, usb - right click, power management and make sure you go through and uncheck the boxs that say "allow the computer to turn off this device to save power". Double check the same for keyboards and mice, then make sure that the box is checked for Under keyboards and mice, under power management "allow this device to wake the computer".
