Wake Source - Read Event Viewer Log

It's funny u mention the cats. There's 5 of them in this house! But I make sure the mouse is turned off and the keyboard is not accessible to them.
The logitech receiver is plugged into an extension is all so that I can bring it to the front for better reception but it's not in a hub.
I'll report back after I try just unplugging it and see what happens. Maybe overnight tonight.

You might see if it may help to have the USB receiver for them connected in another USB port that's connected directly to the motherboard instead of a USB hub.

Do you have cat or something that could be bumping the mouse or stepping on the keyboard that's causing them to wake the PC?

It's fixed. It must have been the extension cable. I swapped that out with another and it hasn't awakened since.
weird cause it wasn't even an 'active' cable and the recvr worked fine.

Hi Shawn. Mine woke up at 3:30AM after being programmed to hibernate at 2:30 AM. The reason in Event Viewer was "unknown." Only the keyboard in a pullout drawer can wake from sleep but not hibernation: only the top of the case can do that, or a wake timer, which would have shown up in the logs. No cats, no dogs. We had moths a few years ago but I'm ruling them out. :)

Hey pxfragonard,

Did you also use the lastwake command to see if it may help ID the culprit?

In addition, double check to make sure that "Allow wake timers" under "Sleep" in your power plan settings is disabled in case it may be some task (ex: Automatic Maintenance) waking the PC to perform something.

Power Plan Settings - Change

It probably was something programmed to run and wake to do so, Sean, but I can't disable it since I use it to wake up. But that's no doubt it. I wish I could find out specifically which. I suppose I could go into the scheduler and search for the one that corresponds to the particular time. It's only happened once anyway. Thanks again for your help.

Anytime. The next time it happens, see if the lastwake command may help ID it. :)

That's the problem. The cause in eventviewer was "unknown."

OK. Happened again. Here's what the log shows:

2:39:58 AM The WinHTTP Web Proxy Auto-Discovery Service service entered the running state.

2:46:58 AM The Microsoft Software Shadow Copy Provider service entered the running state.

2:47:24 AM The Windows Modules Installer service entered the running state.

2:50:03 AM The Volume Shadow Copy service entered the stopped state.

2:53:03 AM The Microsoft Software Shadow Copy Provider service entered the stopped state.

3:00:07 AM The start type of the Windows Modules Installer service was changed from demand start to auto start.

3:00:07 AM The start type of the Windows Modules Installer service was changed from auto start to demand start.

3:00:08 AM The Windows Modules Installer service entered the stopped state.

3:02:28 AM The WinHTTP Web Proxy Auto-Discovery Service service entered the stopped state.

3:31:07 AM The Windows Image Acquisition (WIA) service entered the paused state.

3:31:17 AM The browser has forced an election on network \Device\NetBT_Tcpip_{985C0C45-C0B6-4C0C-A979-D4F66E9A13DF} because a master browser was stopped.

3:31:16 AM The system is entering sleep.

So it went back to sleep and then to hibernation an hour after that but how do I change the time of that installer service? I see you can do it in Windows 8 very easily but can't find out how in Windows 7... or do I want to ? It's not that big a deal in the grand scheme. But curious, as always.
