I realize that the MS Wireless Mouse is not Windows hardware but I don't know where else to ask. The MS wireless mouse 5000s used in both my Win 7 and Win 8.1 systems ignore their power management setting that is supposed to prevent mouse movement from waking the systems from "sleep". The Logitech M310 wireless and every wired mouse I own obeys the command. Only the 5000 ignores it. The keyboard is a wired MS 600 so the mouse is the only device on its receiver. I'm wondering if anyone else has noticed the behavior but found the fix.
