Can I differentiate between waking the Windows OS (Windows 7 and/or 8) from a mouse click vs mouse move? I only want the system to wake upon a click on the mouse but not when I move the mouse. I assume this is not a functionality considered in the Power Management options but maybe something can be done in the Registry? Any ideas?
It would be a cool feature to have, but unfortunately it does not appear to be possible; Windows can be configured (via the 'powercfg' command -- 'powercfg /?' for more detail) to treat input from a given USB HID device as a reason (or not a reason) to wake from sleep, but not to differentiate between types of input. Writing a program to do that sort of differentiation would be relatively trivial, but by the time the machine can run that program to decide whether or not to wake up, it's already awake, and would instead have to decide whether or not to go back to sleep -- which probably doesn't help.
As a workaround, you might consider simply disabling the mouse as a device that can wake the PC; if you don't have a keyboard on the table next to the mouse, then this may not be a useful option, but it looks to be as close as you're going to get to what you're looking to accomplish. To do so, open a command shell and run
You'll see your mouse device named in the list, possibly along with other devices. To disable wake input from the mouse, do
And if you decide to re-enable it later, do so via
Or you could just switch off the wireless mouse when you're not using it, which as a bonus may make its battery last a little bit longer.
