Windows 8.1 will not sleep

Thank goodness I'm not the only one. It's also nice to have someone else trouble shooting these things too.

Nothing has worked so far but I'm going to try this media center fix next.

How did you get on? Did the media centre fix sort it?
 
Have you tried changing the automatic maintenance settings? Took me a while to track this one down as it doesn't appear to use a regular scheduled task. Just search for automatic maintenance from the start menu, then untick "allow scheduled maintenance to wake my computer"
 
Thanks for checking back lads.

Jase, I couldn't find the windows media scheduled maintenance. The only four I can find are in my last screen shot... I even went into the player and checked every tab in the settings.

zola, thanks for that tip, I just accessed that from the start menu and found the weird window to change that setting (so odd they only allow you to change it from there) but the 'allow to wake' box was not ticked.

I still haven't fixed the issue at all. I'm so close to just wiping the SSD and reinstalling 8.1 from scratch instead of that always-worked-flawlessly-in-the-past update from 8 to 8.1.

If you go into Task Scheduler and click on the arrow next to Task Scheduler Library> Microsoft> Windows> Media Center then in the right hand window double click mcupdate_scheduled and click on Conditions tab then remove tick from 'Wake the computer to run this task".

I took a browse through task scheduler and cannot find Media Center (see screenshot) but I clicked on everything that could potentially resemble media center and all had the wake computer box unticked.

Well I got it working... good old reformat and fresh install of 8.1.

The update from 8 was causing all kinds of issues, I should have known better tbh. Running smooth as silk now and, after installing all the essentials and fully updating, I've taken a nice image of the HDD with Acronis.

Next time I get even a hint of an issue, restore that puppy while I make a nice cup of tea and it'll be back to perfect before I finish the cup. :)

It's a shame we never found the culprit but I'm really grateful for everyone's help. Thank you!

Why do you use sleep?

Genuine question as Sleep wake time VS Power up time for me are so close it seems pointless even entertaining sleep mode.
 
I don't believe this, it woke up again. Haha!

Since it would remain in sleep for days at a time before the Bluetooth was installed, I'm going to use that as my lead. It's either applied a wake schedule or damaged a non related task.

This time I didn't install the third party drivers and let Windows configure the Bluetooth.

And I'm back to the drawing board again... I have a good checklist to kick me off though :)
 
Wake On LAN also works when the machine is off, in S5:
http://en.wikipedia.org/wiki/Advanced_Configuration_and_Power_Interface#Global_states

As long as the power supply is supplying power to the network card (look at the LEDs to see if it remains on when you shutdown)

I would start by disconnecting the network cable to rule out wake on lan packets waking it up, then take out your mouse, then keyboard, then any other USB devices.

Glad its all sorted for you. Sometimes a full re-install is the only option, shame like but its true.

Just out of curiosity is there a particular reason you use Acronis for taking an image as I use the built in one with Windows 8?

EDIT:

Sorry I didn't read that you were back to having the same prob's. If its any consolation I wasn't aware that resuming from sleep worked in S5 either.

I had another few attempts again and it looks like the network card is the source but I can't seem to find a setting to disable... it's specifically set to "ONLY ALLOW WAKE ON MAGIC PACKET"
 
My efforts to date:

Device Manager.......................'Powercfg /devicequery wake_armed' then disabled all unwanted peripherals
Ethernet Power Management....selected 'only allow magic packet to wake computer'
Advanced Power Settings.........disabled allow wake timers/sleep after/hibernate after
Automatic Maintenance............disabled it from waking computer to run tasks
Services..................................disabled Windows Media Player Network Sharing service
Event Scheduler......................went through every task, only found two enabled events:
TaskScheduler > Manual Maintenance - cannot disable (but last run = never)
WindowsUpdate > AUSessionConnect - cannot disable (last run = today 08:19)

Yet to test:
Hybrid Sleep..........................disabled due to this MS note claiming WoL is not supported in S4 sleep
Homegroup............................disabled



Now here's the strange thing, after applying all these and maintaining sleep for exactly 25 minutes the system wakes and the event log shows this:

10:25
The system is entering sleep.

Sleep Reason: Application API

10:25
The system firmware has changed the processor's memory type range registers (MTRRs) across a sleep state transition (S4). This can result in reduced resume performance.

TWINKLE TWINKLE LITTLE STAR.... AHHHHHH

... OH NOES

10:50
The system time has changed to ‎2014‎-‎03‎-‎19T17:50:20.500000000Z from ‎2014‎-‎03‎-‎19T17:25:47.957884200Z.

Change Reason: System time synchronized with the hardware clock.

10:50
Intel(R) Management Engine Interface driver has started successfully.

10:50
Windows cannot store Bluetooth authentication codes (link keys) on the local adapter. Bluetooth keyboards might not work in the system BIOS during startup

10:50
Firmware S3 times. ResumeCount: 2, FullResume: 506, AverageResume: 505

10:50
Name resolution for the name master1.teamviewer.com timed out after none of the configured DNS servers responded.

10:50
The system has returned from a low power state.

Sleep Time: ‎2014‎-‎03‎-‎19T17:25:44.614192000Z
Wake Time: ‎2014‎-‎03‎-‎19T17:50:21.210520600Z

Wake Source: Device -Realtek PCIe GBE Family Controller

BOOM! So it's the network card?? How??

I saw no need to install the official drivers for my network card previously but I'll try that now and see if that's the issue.

YES! YEEEEEES! It's remained in sleep for the entire night, finally a break through.

So there's only two culprits:
1. Realtek network card - generic non-official drivers installed by Windows
2. Homegroup - correct sharing sharing setup

Given the issues I've had with a Realtek sound card in the past (painstakingly deduced that it was responsible for cashing my rig when paying both BC2 and BF3 on my previous rig) I'm willing to bet that was it.

Jeez, I'd like to think next time I buy a motherboard I'll genuinely steer away from anything using Realtek but it's usually quite hard finding the right configuration.

Thanks for the help everyone. Let's hope that was the end of this, looks like there's quite a few folks with this issue... check out this 100 page thread!!! I never found that when I initially searched.

www.eightforums.com/general-support/28226-windows-8-1-refuses-sleep.html

I'll edit the initial posts to show this as a solved issue and direct them to the summary. Hope this helps someone else fix it faster than it took me. Mods, if you could add a [SOLVED] in the title it would be great.
