Re: DX79SI - wake from sleep fails

I look at the power gadget data, when the system wakes up - you're right once I hit sleep, the screen goes blank. Starting and stopping the power gadget log may also provide historical data points while the system is trying to sleep.

I believe most of the power is being consumed by the processor in zombie sleep - I have a cooler on the rear of my case and I can feel a lot more heat coming of the radiator than normal, but the fan continues to run at idle rpms.

My system has been behaving itself right now - will go to sleep /w hybrid - disk i/o led shows some pre-sleep activity and then system goes to sleep and shuts down the fans.

System going to sleep

KillaWatt system peeks at 230w Power Gadget CPU 90w Processor freq 4Ghz

Well I might have found a resolution to my problem....

I decided to put a power meter to check the power consumption used - disconnected the system from the UPS and inserted my KillAWatt meter - low and behold the system now always goes to sleep and wakes-up (20+ times). Maybe the UPS is providing noise on the power line to the system power supply. I will keep this community updated if the system reverts back to it's old ways.

Only add-on card is a Nvidia GTX 550 Ti - difficult to remove it and re-try, without any video. I tried re-installing the chipset software and management engine interface and got the system to sleep sucessfully twice, but on the third attempt back to before - no sleep.

Power supply is a Thermaltake TR2 600W

Here's an image of all the software I have installed

Just reported a similar problem:

Had some problems trying to get my DX79SI to successfully go to sleep, installed latest BIOS: 0460.2012.3227.1627 and it consistently won't go to sleep.

System consists of Win7 Ultimate SP1 (disbled hibernation & hybrid), i7-3930K, and above BIOS.(all defaults)

When I say it won't go to sleep, the S3 state indicator blinks, but the fans continue to run (the CPU fan/cooler provides significant heat). Only way to re-start the system is to use the Power button (to power off and on)

When the system restarts to Win7 the Intel Desktop utilities shows Processor temp to be around 124F which then drops to around 90F - CPU fan speed is stable and the same when the system doesn't enter sleep state.

Has anyone else experienced this problem - system won't shut down the fans when system goes to sleep, and won't come out of sleep

DX79SI won't go to ssleep
