Windows 7: PC wakes up immediately after going into sleep mode

PC wakes up immediately after going into sleep mode

This has been happening since the last several days. I've tried system restore going back to Dec 31st and it hasn't helped the issue.

I've looked through the Advanced Power Settings options and not found something that appeared to be an issue to me. It still auto wakes up with Allow wake timers set to Disable and When sharing media under Multimedia Settings set to Allow the computer to sleep.

I also ran powercfg -lastwake in cmdafter an automatic wake up and these were the results:

Study the Performance log and utilitze System Resources to see what is waking up Sleep: troubleshooting steps

Sleep issues are almost always affected by the Display driver so see if it has been changed, update it or try another.

If nothing becomes evident, use the tool the Pro's use to trace Sleep issues: Gathering a Startup, Shutdown, Sleep, Hibernate, or Reboot Trace - Windows 7 Forums

You may wish to try this:
- unplug all external, i.e. usb, firewire, attached devices
- start disabling services - after careful reading - as these can sometimes cause what you are describing
- disable all TSR's (terminate and stay resident programs) by ctrl-alt-delete, check what is running in the background and turn them off, one at a time. These include antivirus, net monitors, print spoolers etc.
- check your power settings. I have seen systems where some strange settings have caused problems like this. Try setting them to the default.

Good luck

Hi guys,

Although this topic did solve my problem with PC waking up right after switching it into sleep mode it helped me to find out what was wrong.
As you can see on the Delicieuxz's screenshot the network card wakes the machine up from sleep. In my case it was antivirus process (run as service)
Owner: [SERVICE] \Device\HarddiskVolume2\Program Files\Bitdefender\Bitdefender 2012\vsserv.exe (VSSERV)

So what helped me? I've opened "Power options", selected the plan I wanted to fix (Balanced power plan) and then clicked -> Change the plan settings -> Change advanced power plan settings and from the next dialog window "Power options" I've expanded the branch Sleep, then expanded Allow wake timers, choose Disable.

After that I've found MS article on that ;]

Windows wakes up immediately from sleep
Ok, this is a problem I've had for about 4 months. It's very sporadic and intermittent and despite my best efforts, I've been unable to solve it. I put the system into sleep mode, and almost every time it wakes up immediately. I have narrowed it down to a keyboard issue (Logitech Illuminated...

It's been like this since I installed Windows 7. No device is wake armed except for the keyboard but I sure don't press anything (I'd have noticed and wouldn't be here). When I put it to Sleep it sleeps for a second and then wakes up. If I try again, it may sleep without problems but suddenly...
