Windows 7: Can't wake from S3 with keyboard or LAN - tried all "solutions"

This problem has been annoying me since weeks. I've spent countless hours looking for solutions on google and i can't fix it.

My HTPC can go in S3 standby mode successfully. BUT the only way to wake my computer is to press the power button. When i wake it up, it starts where it was before so S3 mode is working. Problem is just waking it up.

The weirdest thing is that it USED to work. Around 2 months ago i was waking up my computer with my keyboard and it worked. But i stopped to use this feature, and now that i need it, it isn't working anymore.

Oh, also wake-on-LAN isn't working neither. And it also used to be working 2 months ago. I really don't know what happenned.

Here's a couple of screenshots. Sorry my windows is in french, but i'll translate the text for you:



Picture from my BIOS



Device manager -> Keyboard -> Power management
>>> Option "Allow this device to wake computer from standby mode" is checked
>>> Option "allow computer to turn off this device to save energy" is unchecked and greyed out



Device manager -> Network cards -> Realtek PCIe -> Advanced
>>> Wake on pattern match : ACTIVATED
>>> Wake on Magic Packet : ACTIVATED

Can't see it on screenshot but the option "Stop wake on LAN" is DISABLED (i also tryed to turn it on but it doesn't change anything)


"powercfg -devicequery wake_armed" tells me that my keyboard is allowed to wake my computer



"powercfg -a" tells me that S3 mode is supported, but S1 and S2 is disabled (that's normal)


Power configuration :

S1 after : Never
Allow hybrid mode : Yes
S3 mode after : 60 minutes
Allow wake timers : No
Selective USB suspension : Off



My hardware:
AMD A6-3650 APU W/ AMD Radeon 65XX HD / Socket FM1 2.6GHZ 4MB 100W
Gigabyte A75M-D2H
Antec Fusion Remote Black HTPC Case
Seasonic 450w 80+Gold (fanless)
4GB G.SKILL Ripjaws X F3-12800CL9D-4GBXL DDR3-1600
Crucial M4 SSD

Solutions tryed, uncessfully:
- resetting BIOS/CMOS
- updating BIOS and all other drivers to latest versions
- disabling all other USB devices
- tryed every single USB slots, with and without USB hubs, usb2 instead of usb3 and vice-versa...
- tryed with two different power supplies
- tryed different keyboards
- tryed mouse instead of keyboard, LAN instead of USB...


Seriously..... I'M DESPERATE !!! It used to work. Why it won't work anymore

First try system restore to the time before the issue started. If restore is unable to repair.
System Restore
Try sfc /scannow? If this does'nt do it.
SFC /SCANNOW Command - System File Checker
Try Repair Install.
Repair Install

Just tryed everything you said... still same problem

sfc /scannow didn't report any problem. I did a successful repair install of windows 7 and i still can't get out of s3 standby with my keyboard

You could try running an energy report and see if it shows something that might cause the issue.
It's helped me a few times, but i never had your specific problem...
To get the report, from an elevated command prompt type:
Powercfg -energy

UPDATE
Did a couple of other tests using other keyboards and adapters laying around. Just found out that i can wake my computer using a PS2 keyboard. But this PS2 keyboard won't work in USB port if i use a USB to PS2 adapter.
Here is the result of my tests :

10-years old PS2 keyboard:
- PS2 Port : Able to wake PC using PS2 port
- USB Port : NOT able to wake PC using USB to PS2 adapter

(USB) "No name" cheap mini keyboard bought on ebay :
- PS2 Port : Able to wake PC using PS2 to USB adapter
- USB Port : NOT able to wake PC using USB2 or USB3 ports

(USB) Frisby cheap keyboard bought on ebay :
- PS2 Port : Able to wake PC using PS2 to USB adapter
- USB Port : NOT able to wake PC using USB2 or USB3 ports

wireless IOGear GKM681R
- PS2 Port : NOT able to wake PC using PS2 to USB adapter
- USB Port : NOT able to wake PC using USB2 or USB3 ports
- This keyboard used to be able to wake my PC 2 months ago

Acer USB keyboard KU-0355
- PS2 Port : NOT able to wake PC using PS2 to USB adapter
- USB Port : NOT able to wake PC using USB2 or USB3 ports
- This keyboard used to be able to wake my PC 2 months ago


So, i'm still not able to wake computer using USB ports, no matter what i do. Wake-on-lan still doesn't works.



Damn, my report is all in french since my windows is in french. So if i post it, you will not understand anything.

There's an error related to "selective shut-down of usb devices" feature because it is currently desactivated. Am i supposed to activate it ?

There's also an error for each of my USB controllers, saying it does not shut-down itself when not in use (this is supposed to be what i want to do, right ?)

A problem for me is i want things pretty much the opposite of what you want.
My primary is an HTPC and i don't want many things waking the PC.
I've had problems with wireless mice, network, etc., waking my PC, so i disabled most things by choice.
The only things i want (and do) wake my PC are the remote control and the power button.

RE: "selective shut-down of usb devices"

I don't find this in my energy report.

The only thing i find in my report for "selective" is:

Power Policy:USB Selective Suspend is disabled (Plugged In)
The current power policy has globally disabled USB selective suspend.

RE: "There's also an error for each of my USB controllers"

For my USB devices i get a lot of these types of errors:

USB Suspend:USB Device not Entering Suspend
The USB device did not enter the Suspend state. Processor power management may be prevented if a USB device does not enter the Suspend state when not in use.
Device Name USB Root Hub
Host Controller ID PCI\VEN_1002&DEV_4398
Host Controller Location PCI bus 0, device 18, function 1
Device ID USB\VID_1002&PID_4398
Port Path

Well i just wanted my wireless keyboard to wake the PC (like i was able to, 2 months ago). I just tested with other USB devices to try to figure what was the problem. Currently i unplugged everything except keyboard.

That's exactly what i was trying to translate ! I have the same thing in my report.



Yep, i'm also getting many of these errors. That's the other thing i was trying to translate.

So i guess my reports are all fine. All settings seems to be correct in Windows7, and it's still not working after a repair install. I think it is definatly an hardware problem, but i can't understand how it happenned suddently when it was working 2 months ago...

If all else fails there's always system recovery to try.

No, system restore was disabled

Hi Anarchoi. I had the same sort of problem on a newish XP system. I couldn't see the "Power Management" tab in the Device Manager to enable my USB mouse to wake the system. I did this:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\usb
"USBBIOSx"=DWORD:00000000

As suggested by Microsoft

Now all good!
