Stop Your Mouse from Waking Up Your Windows 7 Computer
If you use Sleep Mode on your PC, have you ever noticed that moving your mouse will wake the computer from sleep mode? If you would prefer to only have the PC wake up when you hit a key instead, there’s a simple tweak.
You’ll have to click the “Change settings” button before you can see the Power Management tab
And now, you can uncheck the box from “Allow this device to wake the computer”.
