waking from suspend for unknown reason

[feh]

Hi folks.

I'm using Win7 exclusively for its media center capabilities. As such, the machine is usually sleeping.

When I leave for work in the morning, the machine is suspended (S3), but when I come home in late afternoon, it has resumed and is running at full power.

Anybody know why this would happen? How can I determine what's causing this?

Thanks!

Hello Feh,

The items listed in the tutorial below may be able to help you determine what is waking up your computer. A usual cause of this is the "Allow to Wake computer" option checked for the Network Adapted (STEP SIX), or the Multimedia settings -> When sharing media is not set to "Allow the computer to sleep" (STEP TWO).

Hope this helps,

If what Shawn suggested about the Media sharing doesn't work, some easy things to look at are the drivers for the NIC, KB, and Mouse in the device manager. You can unceck the power management options safely and see if that helps.

Thanks for the replies.

I've already verified the NIC is not allowed to wake the machine. I'm using a wireless keyboard/mouse, and I'd like the kb to wake the machine on a key press.

I've used the same kb/mouse w/ a Vista machine, and it didn't wake up like this, so I doubt that's the problem.

When I get home, I'll go through the doc previously posted.

Have you checked what woke the computer yet using the below command?

powercfg -LASTWAKE

Here is an example output

G:\Users\mikinho>powercfg -LASTWAKE
Wake History Count - 1
Wake History [0]
Wake Source Count - 1
Wake Source [0]

Nope. That's the first thing I'll do tonight.

Do you have a cat? My cat used to wake my PC via Space Bar all the time. RIP Baby Mama.

LOL i love it

 

[mikinho]

btw, the command to show all devices that can wake the system is:

POWERCFG -DEVICEQUERY wake_from_any

For wake from S3 use

POWERCFG -DEVICEQUERY wake_from_S3_supported

Hope it helps

powercfg -wake_armed

after that disarm all devices listed, usually its mouse and keyboard

powercfg -DEVICEDISABLEWAKE devicename

personally i soldered a extension wire to the powerbutton on the motherboard and put a little pushbutton on my desk.

I've set powerbutton to Sleep. So when i leave my desk i push the button, after i return i push it again.

It turns out that the program mcupdate_scheduled is what's waking the machine. Is that the process that downloads the program guide, or something else?

I would think the machine would resuming sleeping after that task, but apparently not. Anybody know what I need to configure to get the machine to sleep after that task completes?

Thanks.

change the schedule of the updater to update during a time you usually use the computer.
or you can set a task in taskscheduler. Set it to force sleep at a certain hour.

Last thing to check, and probably the least, is see if your BIOS is set to wake at an alarm time. This is probably not it, but wanted to throw it out there. Just something to check.

Yeah, I can do that, as a workaround.

But, this seems to be a bug. The machine should go back to sleep after updating the schedule (if that's what it's doing).

Is this a MS-sponsored board? Are there MS engineers reading this? If so - please fix this.

 

[petrossa]

It's an issue since way back. it seems it's too much work to really fix and is not high on the annoyance list.
I have a lot of tasks which close other tasks and put the computer back to sleep. When i do the computer cleaning at nite. If not my wife wakes up, and just pulls the plug

This is for the ehome service right? For media center? I have media center setup on my TV, main PC, and home theater. My sleeps fine on all 3 of my machines. If you do not use the Media Center service you can always stop it from starting, but it should be sleeping after it updates. If you do use the media center, maybe check the box to "run optimizations" in the media center options, forcing it to refresh it's services at a specific time?

What you have going on is not normal, nor have I ever experienced it on Windows Media Center 2005, Vista, Or Windows 7, and that is how I have been watching TV since. My machine has never woken up to update, only to record, then if it saw it had a network connection it would update.
