Windows 7 unable to sleep

[tomcage]

Hi, I've just installed Windows 7 on this hardware:

ASUS P5B Deluxe WiFi-AP
Intel Q6600
4GB RAM
XFX GeForce 9600GT

Everything is working great, apart from the fact that it won't go to sleep. When I try to enter sleep, it goes through the motions but then instantly wakes up agian. I have run various diagnostics to work out why, and everything is pointing towards "Intel(R) 82801 PCI Bridge - 244E" - however this hasn't helped me solve it so far!

The Intel device shown above is listed as the wake source in event viewer and powercfg. I've updated the BIOS to the latest version, and as far as I can tell, the BIOS is set to not allow PCI devices to wake the system.

I've installed the Intel chipset drivers, and the ASUS ACPI driver, to no avail.

Any ideas?

Many thanks,
Tom

Hi, thanks for your reply.

I have seen that help topic before, but have never followed it all the way through for some reason...

I used the powercfg -devicequery wake_armed command and went through the list, disabling each one.

Anyway, I fixed the problem - turns out my Logitech bluetooth keyboard and mouse (MX5000) were the culprits. By disabling "Logitech HID-Compliant Keyboard" and "HID-compliant Bluetooth Mouse" in device manager, the system is able to sleep.

Thanks for your help again

Hi, I have the same issue but what's the fix, as opposed to the work around?

My PC attempts to go to sleep, then instantly awakens. If I disable 'Allow this device to wake....' for my keyboard and mouse, then it sleeps like a baby.

However, I actually want my keyboard and mouse to be able to wake my machine.

Has anyone come across an actual solution to this problem.

Cheers,

Jon C

Try disabling wake timers under power options-advanced settings-sleep-wake timers.

Some wireless laser mice have to be turned off as they are too sensitive and cause the machine to wake. Mine has a little power switch on it I use.

Thanks Andrew.

Unfortunately I need wake timers enables to allow my backup software to run over night.

On the mouse front, I have disallowed the mouse from waking the machine, leaving just the keyboard and NIC. It still won't remain asleep. If I also disallow the keyboard, it sleeps perfectly.

Cheers,

Jon C

Odd. What happens when you try a different keyboard? Do you have a cat? Could be someone or something hitting those keys...

Check powercfg -energy Report

You could aswell try following, this will give you detailed information on what driver/setting might cause you trouble:

-start CMD-Shell as Administrator
-type powercfg -energy
-wait ~60sec.
-browse Report Location (C:\Windows\system32\energy-report.html)
-copy report to desktop (could not directly open from stored location on my machine)
-open report with any browser
-check errors(red)/warnings(yellow) to find the source of your problem

You might aswell post that report here so somebody can look it up for you if you can't interpret the output.

In case you do not find the report file in Systems32 folder browse to this location:
C:\ProgramData\Microsoft\Windows\Power Efficiency Diagnostics
