Can't wake from S3 with keyboard or LAN

[anarchoi]

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

UPDATE

Just tryed doing a "repair" installation of Windows 7 .... didn't help

I also 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.

Looks like a motherboard problem ?

That's because you haven't enabled the USB Legacy Support in the BIOS first, therfore you have no drivers until Windows load them.

[anarchoi]

Yes, USB Legacy Support is enabled (and was always enabled). I just double-checked before posting.

This is seriously the most weird/annoying bug i've had with my computers. I've tryed all solutions and can't fix it. Maybe should i RMA my motherboard ?

[Dark Mantis]

Try disabling the Legacy USB support and then rebbot before enabling it again and rebooting. Have you tried another keyboard as they do go faulty and would give this exact scenario.

[anarchoi]

yes, i also tryed that (desactivating then reactivating USB Legacy)

I also tryed many other keyboards, i posted the results of my tests in my second post

None of the keyboard are able to wake computer using USB port, but some of them works using PS2 port

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

I would say that it is a BIOS issue then in as much as the PS2 port works but the USB isn't having the drivers loaded by the Legacy Device and so isn't working. Try contacting GGTS and explain the issue and they should be able to customise a BIOS for you.

still waiting on an answer from Gigabyte :/

[anarchoi]

Still no answer from gigabyte tech support.

I'm having all kind of problems with this s***ty motherboard. Now when i boot my computer or wake it from sleep, half of the time everything plugged in the USB ports won't work until i unplug and replug it.

I'm done with gigabyte, forever. I've never had so much trouble with a motherboard. I will never ever buy a gigabyte product again.
