Windows 8.1 will not sleep

trentlad · 4 Feb 2014 at 16:30

EDIT: SOLVED - see my final posts for all settings changed and two main culprits

Any suggestions to keep Windows 8.1 asleep?

These two are the only suggestions I've found and they haven't solved the issue:
1.) disable Wake on Pattern Match
2.) disable all autonomous 'Sleep' items in Advanced Power Settings

I've been trying to setup WoL (Wake on LAN) but my rig wouldn't remain asleep for more than 10 minutes. Option #1 cured the issue completely... until I purchased a Broadcom bluetooth dongle and the sleep problem reappeared immediately after instillation (I've even tried removing the dongle to no avail).

HHHEELLPPP!?

I had the same issue, disable IPv6 on all of your network devices. That should fix it.

Thank you Malachi!

Just to be sure I didn't miss a setting, for each device I only disabled the four IPv6 options shown in these two windows.

Unfortunately it's still majestically waking, so were there any others?

Have you checked in task scheduler to make sure nothing else is waking your computer?

Let me check...

Find the Bluetooth device. Right click and properties the device. Click on Power Management and untick 'Allow the device to wake the computer' as it's only happened since you've installed the Bluetooth device I'd say it was this that was waking your PC.

Thanks a lot maccas, it was unticked already

I need that for Wake On LAN, which is only the entire reason I'm going through this. Haha

Hmm looks like there was one manual maintenance item with the allow to wake option selected. Lets see if that was it. I also disabled the other two shown in the image.

BY JOVE I THINK YOU'VE CRACKED IT JASE!

It remained in sleep for a full 20 minutes. Tonight will be the true test, hopefully it'll stay in sleep all night. I'll post an update tomorrow.

Thank you very much Jase and also to everyone else for offering advice.

Oh boy... it's still waking up and the event log doesn't show a thing. This is insane.

I'll take a look at the media centre settings.

Mate I have the same problem as you...

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.

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.

Once it's woken up, what does running "powercfg -lastwake" in a command prompt show you?

Let me check...

Here's what I get after setting it to sleep (7 minutes later it awoke upon its own accord):

Sooooo um... what's this supposed to tell us?

trentlad · 3 Mar 2014 at 10:24

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!

trentlad · 3 Mar 2014 at 16:11

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

trentlad · 3 Mar 2014 at 16:18

Hi Twst! I'm not using sleep for any boot speed reasons, I'm setting up WoL.

trentlad · 3 Mar 2014 at 17:15

Seriously! I never knew that, I'll take a look into this and see if my motherboard supports it.

trentlad · 19 Mar 2014 at 19:30

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"

trentlad · 19 Mar 2014 at 19:30

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.
