Windows 7: 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 Keyboard) because it has never woken up immediately when I disconnect said keyboard. And sometimes it DOES sleep with the keyboard plugged in, but not often. I've tried powercfg -lastwake and using power troubleshooter in event manager and come up with either 'unknown' or 'power-troubleshooter'. I've disabled all power management wake modes for all the devices like LAN and USB in device manager but it doesn't cure the problem. I used a sleep utility to try to help but it made no difference. Anyone got any genius words of wisdom? Something I haven't tried yet? It really is frustrating the bejesus out of me.

Err... replace with a different keyboard? I'm only half joking

I don't have a spare one lying around and I don't know anyone else who does. But yes, I had thought of that...

No, this is not the problem - tested the same keyboard on another machine, and it went to sleep no issue. I really have no idea what the problem is here.

Do you have a Dual boot setup?

See here: Won't sleep - just goes back to desktop

I did, yes, up till about 2 months ago then I removed XP and went back to just having Windows 7 alone.

Are you sure the problem didn't start around the time you removed the dual boot setup?

What does Disk Management look like? Can you post a screen shot of it?

I had the EXACT same issue after getting the Logitech Illuminated KeyBoard (love it - BTW).

This should solve the issue: Go to the Device Manager & find "Logitech HID Compliant Keyboard". Right-click > Properties > Power Management Tab and Uncheck "Allow this device to wake computer".

That should do it!

To confirm what woke up your Windows from sleep:

Start> Type CMD in search box> Click on CMD.exe in results above> Type in:

powercfg –lastwake

Enter




To get the more detailed info on the device that wakes your Windows up during the sleep, and the most likely suspect, type:

powercfg –devicequery wake_armed

Enter



If the PC was last awoken by itself, this will be you culprit

A Guy

Possibly did. I've attached a grab of Disk Management. Cheers.
