I've set my HTPC to wake on LAN (from magic packet only). However, a few times per day my HTPC wakes up by itself.

Is there a way i can know how it wakes up, which device sent the WOL magic packet ? I really don't understand why it is waking up by itself since i haven't sent the packet...

If you turn the WoL off, does it still wake itself up?

Are there any clues in the Windows Event Viewer?

Well if i disconnect my LAN cable from the HTPC it will stop waking itself up

How do i check the Windows Event Viewer ? I have windows in french so i'm not sure where it is and how it is called

I just noticed "powercfg lastwake" says the last wake event was a timer ???

Then is looks like it is a scheduled task waking it up.

I'm not sure how to best hunt thru each task, but the info is in the same management console that I showed in my post above. Expand the tree for the Task Scheduler.

One easier method might be to disable the WOL option in the NIC, if your Network card has this function they will be in the local area network - properties-confugure dialog

they may be named differently but here is a snip of the ones on my NIC, sometimes disabling one of the wake options will still allow the remote wake but stop the local wake

I want to let WOL enabled because i use it to wake my computer with a magic packet.

I have disabled wake-on-alarm in my BIOS and in Windows, but my computer keeps waking up by itself and "powercfg lastwake" says it was waken by a timer.

One thing it may be is a Scheduled task timer related to a windows process, for example The windows Media centre is set by default to check for online media for use with songs, Cover images etc, and I think this has the wake option set - The Microsoft items tend to be set to operate around 3AM so if your wakes are at this sort of time that may be an avenue worth investigating - I actually switch all retrieval options for WMP & WMC off in their own controls so do not have the wake issue - but it could be anything, if the event is at a set time this would make your search through the scheduled tasks a little easier

No the computer was waking up by itself 2 minutes after it went to sleep

I just discovered that it was caused by Samsung SSD Magician. I uninstalled the program and it's better now.

Just looked at every items inside the Event Viewer for the Task Scheduler... The only task set to wake the computer is WindowsUpdate but i can't disable it :(

Glad to see you found it :)

What you may be able to do, for the update, is go into the actual task and change the activation time to one that is more compatible with your needs, setting it to 3 PM rather than 3AM (or whatever it's set to), would be more likely to activate when the system is on.

A more drastic alternative would be to set windows update to not check for updates - of course this would mean that you would have to manually perform this task, and risk running a system that is not as secure as it might be

It's already disabled in BIOS.

Now that i removed SSD Magician the problem happens less frequently but my computer keeps waking up by itself, just less frequently.

It just happenned again 2 minutes ago. But "powercfg lastwake" isn't showing anything anymore. So i can't tell what has waken the computer...

One obvious but often overlooked item is the humble mouse - with the high resolution of modern mice it's not unknown for the slightest touch on furniture to move the mouse enough to wake a system
