Help CPU wakes up on after 1 minute of sleep

post #1 of 15
Thread Starter 
My cpu used to sleep well. It would fall asleep on Q and wake up on Q to record movies etc.

Now it doesn't sleep when it is supposed to and it wakes up on its own after 1minute of sleep. I ran a cmd prompt to help me figure out what wok it, and the response was Realteck pcie gbi family.. could it be my ceton tuner. This never happened before. My tuner would only wake the cpu when it was about to record a program.

At the end of the day, I am aware that this is not that big of a deal. a lot of people keep there cpu on 24/7. However I like my sleep setting. More over, I am really annoyed that it used to do what I wanted it to do and it is no longer do so and I don't know why.


Thanks for the help.

In device manager, make sure your Realtek is set to wake on magic packet only. Otherwise just about anything will wake it.

An automatic driver update could have easily changed that parameter.

A rogue USB device can cause this kind of behavior, too. Have you plugged anything new in lately?

I will check that in the device manager. I'm pretty sure that I had this setting already, because again everything used to work. I can not figure out for the life of me why it would have changed, but I will check my settings tonight.

Well I have been using the logitech k400 keyboard for quiet some time now. I've felt as though it has been acting kind of quircky resently. I will try to change the batteries and see if that changes anything.

Thanks

Also make sure Wake On Pattern Match is Disabled. That one has bitten me a few times.

If this is a wake on LAN problem, as well as the other suggestions you may need to try disconnecting other devices on your LAN and connecting them one at a time to see if/when the problem goes away/returns.

Any other device on the LAN (e.g a Smart TV, or other DLNA device) might be waking the PC. My Squeezeboxes have a bug where periodically they will continuously wake the PC with the server (with magic packet) until they are restarted, then the problem goes away for a month of so!

To diagnose what's going on, once your PC has woken up, run an elevated command prompt and enter the following command: powercfg /lastwake

This will tell you what device woke up your PC from sleep or hibernation...

This.

In my case it was an Xbox I am using as an extender. I used to leave WMC running on it all night, now I make sure to stop it b4 going to bed.

I have to leave the Xbox on all the time because my mom does not know how to start it up when she wants to watch TV, but I like to put the PC to sleep.

If your mom knows how to use a remote, starting it up should be no problem. You can easily set it up to go straight to media center automatically. Just make a macro that turns on the TV and the Xbox. So to the end user, it works exactly like a cable box.

Well, mostly. The delay from 1. the Xbox booting up, 2. the PC waking, and 3. the delay as the Xbox connects with WMC can get kind of long. Due to her Alzheimer's, she expects to see something on the TV screen almost immediately. Otherwise, she starts pushing buttons which mucks things up. Keeping the Xbox running all night seems to work for her.
