Got a problem: my PC won't idle to sleep.

But I've narrowed it down to the following:

Using a Powershell script that calls win32.userinput, and a ten second loop, I can watch the idle time and last user input time. What this shows is that if I stop typing / moving the mouse, the idle count starts to increment (as you would expect). Until it gets to around five minutes and fifteen seconds, and then it resets to zero. There will then be a second occurrence of this after another five minutes, but not a third (at least not always).


How can I figure out what causes this? I would like to remove it.


I've tried disabling every HID in device manager (leaving just either the mouse or keyboard) but that makes no difference

Every driver is up to date as far as I can tell

The install of windows is clean, from about ten days old (v2004)

I've checked the event viewer but can't see anything

I've checked Task Scheduler for something that has a trigger of idle (and a wait of five minutes) but can't see anything
