First off, there are a few devices that you probably won't think of right away that can wake up your machine.  On my Precision M4700 I had 2 fingerprint sensor devices that had this function turned on.  Here is a way to inventory machines and find out the devices that have wake capabilities.  Including NIC cards if WOL is enabled.

Create a new software record in KACE.  Call it Devices with WOL Enabled

Make sure all Windows OS are selected.  VERY IMPORTANT!

Custom Inventory Rule:  ShellCommandTextReturn(powercfg /devicequery wake_armed)

This tells the system to run the command   powercfg /devicequery wake_armed and return the value(s) if any into this Custom Inventory Record (CI).

That should do it...enjoy.
