Computer Wakes From Sleep Every 15 Minutes

Jul 18, 2014

I just got a new Win 8 computer. I love it, however it wakes from sleep mode every 15 minutes on the dot. It will wake for about 2 minutes than sleep again.

Is this something it should do in order to get some air flow every once in a while or can I stop it from doing this? I have searched around online and tried everything i have come across. I turned off the setting that allows programs to wake the computer, as well as made sure the ethernet connection doesn't wake it.

Computer Not Entering Sleep State - Set It At 30 Minutes

Aug 4, 2014

As the title says recently my computer is not getting into sleep state although i've set it at 30 minutes.

Tried a lot of stuff like energy-report from power cfg:


System Availability Requests:System Required Request

The device or driver has made a request to prevent the system from automatically entering sleep.

Driver Name FileSystemsrvnet

Though i cannot find which device is causing it.

Already checked all devices in device manager but didn't find anything related.

Computer is going to sleep if i click it , just refuses to go automatically.

Windows 8.1 Pro - PC Wakes Up In Sleep Mode With Error

Jun 27, 2014

I am running Windows 8.1 professional. I was just wondering, as I am having some concerns with my pc sometime through the night as it just wakes up for no reason.

I am not sure if someone is accessing this remotely or what but sometime I see a folder that is open or my email that shouldn't be or at least I think I have closed it before I put it to sleep.

I am not sure what to do as I have run my antivirus software with little showing up and my malware, completing a full system scan.

I also have looked at my even viewer pictured here to see if there is something unusual or strange happening.

CPU Increase Each Time Comp Wakes Up From Sleep

Jan 3, 2014

I recently noticed this strange behavior in my pc. When I restart my computer, cpu usage will stay around 20%, and fluctuate the usage of my processes (system host and firefox being the big hitters) to maintain this general figure. Upon putting my computer to sleep and reawakening, the symptoms are the same, except the usage hovers around 40%. This will continue until usage hovers around 99-100%.

I also just noticed that your TSG SysInfo (included below) says i have windows defender disabled, but I have been under the assumption that it is enabled. It has been since i uninstalled AVG as this was once a heavy hitter in my processes and I thought a cause to some of this.

Before this I didn't think this was a virus, because I've run multiple malware searches including malwarebytes in and outside of safemode but now I'm not so sure.

Also most likely related, my pc takes (literal) hours to shut down.

Windows 8.1 Laptop Wakes Unexpectedly From Sleep

Nov 25, 2013

I've clean installed windows 8.1 pro vl x64 in my laptop (Windows Media Center is not installed of course). and activated successfully with KMSmicro 5.0.1. Windows is fully updated.

I have this problem: it wakes unexpectedly from sleep at either 04:00 or 05:00 at night.

I check in the Event Viewer and the first entries after the wake are always, eg.:

Event: Kernel-General
The system time has changed to ‎2013‎-‎11‎-‎24T03:19:07.500000000Z from ‎2013‎-‎11‎-‎24T00:19:12.031510800Z.
Change Reason: System time synchronized with the hardware clock.

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

Event: Power-Troubleshooter
The system has returned from a low power state.
Sleep Time: ‎2013‎-‎11‎-‎24T00:19:02.334201600Z
Wake Time: ‎2013‎-‎11‎-‎24T03:19:09.179443500Z
Wake Source: Unknown

The following is what I've tried so far based on these two links:
Spoiler: [URL] ....

1a. Go to Device Manager - Select each keyboard and mouse device and right-click Properties - Go to the Power Management tab and untick "Allow this device to wake the computer".

1b. Double checked the above for my onboard ethernet network card

2. Checked in Task Scheduler and no active task is set to allow to "wake the computer to run this task" having such launch time.

3. Checked in Automatic Maintenance and "Allow scheduled maintenance to wake up my computer at the scheduled time" is disabled.

4. Ran cmd as admin, and:

C:Windowssystem32>powercfg /lastwake
Wake History Count - 1
Wake History [0]
Wake Source Count - 0

[Code] .....

5. checked in Power Options>change plan settings>change advanced power settings and the "Allow wake timers" is disabled for both On Battery and Plugged in.

6. There's no relevant setting in the BIOS.

Debugging :: Windows 8 Crashes After It Wakes Up From Sleep Mode

Sep 15, 2014

I've actually had this problem for a while, I really should have taken care of it sooner. It is mostly because I found ways around it, which probably aren't too good for my computer. If I leave music running in the background and put the computer to sleep then the error won't occur. Needless-to-say - and as the title says- The system crashes upon waking up from sleep mode. The screen turns blue and says: "Sorry, your computer encountered an error and needs to restart. We're just collecting some error info, and then we'll restart for you" The results from the diagnostic test have been attached

System recoveries and restores haven't worked, hence the reason why I've sort of given up on the problem until now.

My Specs
CPU: AMD FX(tm)-6100 Six-Core Processor 3.30 GHz
GPU: Geforce GT 640

This is a backup task I've been using for several years with Windows 7 machines, but only recently started adding to Windows 8.1 boxes. The strange behavior is as follows:

-If the computer is on, the task will start at the scheduled time and do it's thing.

Computer Wakes At 3:14 AM To Sync Hardware Clock

Oct 6, 2013

I am tired of having a computer in my bedroom waking up sometimes multiple times in the morning hours--like approximately 3 or 4 A.M. Support people have tried to stop this operation but to no avail. It still is doing it although less frequently now. This morning at 3:14 A.M., it woke up automatically and then shut down a few minutes later.

In Event Viewer it said at 3:14 A.M.: The system time has changed to ‎2013‎-‎10‎-‎06T10:14:28.500000000Z from ‎2013‎-‎10‎-‎06T06:11:17.671868600Z. Change Reason: System time synchronized with the hardware clock. I attached a screen shot of the info in Event Viewer, for your reference.

Why does the computer have to do this at 3:14 A.M.? Can't this occur some other time like during the day when the computer is running?

Windows 8.1 Goes To Sleep Within Few Minutes Of Staying Idle

Jun 21, 2014

My Windows 8.1 pro desktop system,is going to sleep after a few mins of staying idle.I was having windows 7 before this and I never faced any issue.It was recently that I upgraded my OS to windows 8.1 pro. This is a clean install of the OS.

By staying idle, I mean, I am reading some newspaper or some pdf file or something like that online without any activitiy on the keyboard.After a few mins, it automatically goes into sleep mode. This is making me mad, as I could be in the middle of something while reading documents and it goes into sleep.

In the power options, I have changed it to High Performance plan, I have verified that, "Turn of Display" and "Put the computer to sleep" options are "Never". When I click on "Advanced Power Settings" , I can see that , under sleep, "sleep after" is never. Allow Hybrid sleep is "Off". Hibernate after is "Never".

I just wanted to add, that the event viewer shows the following entries...

The system is entering sleep.
Sleep Reason: System Idle

The kernel power manager has initiated a shutdown transition.

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.

The system has returned from a low power state.
Sleep Time: ‎2014‎-‎06‎-‎21T05:51:33.970250600Z
Wake Time: ‎2014‎-‎06‎-‎21T05:52:23.968079800Z

I also tried to create a new power profile but this did not work. I ran sfc scanow and also fixed errors. I have all latest windows updates. I have also tried DISM

I can't even read something without fear and I have to keep moving my mouse every minute and I can't even concentrate.

Computer Takes 20 Minutes To Start-up

Apr 17, 2014

After a windows update crashed during startup, my laptop is taking 20+ minutes on the "welcome" loading bar after you login. The login screen itself it very laggy and takes 5 minutes to navigate. The "Lenovo" loading screens upon startup takes 3 or 4 minutes.

Occasionally a black screen will appear and I cant get past it in the loading process.

Maintenance :: Windows 8.1 Computer Takes 4 Minutes To Shut Down

Jan 3, 2014

I have a Dell XPS 8700 Desktop, has 8GB of RAM and a 1TB hard drive, running Windows 8.1 which I had installed the day it came out..the PC I purchased in September 2013..for the past few weeks I have noticed how when I shut down the pc that it can take up to 4 minutes to shut down, the monitor will go black but the power button the tower will remain white til it turns off, it used to turn off in a matter of seconds, now its minutes..same issue for restart, takes about 3 minutes to restart and no one from Dell can figure out what the problem is..all I had installed in December were updates from microsoft thats it, other than that nothing new has been installed. Yesterday I got a notification from Dell on my PC notifying me that I should update my BIOS which was A4 to A6 which I did and still the same issue..talked to five technicians and no one can figure it out, been told maybe its software related and I need to reformat the hard drive, I feel that would be a waste of time, if there was an actual cause I would do it, but to format my hard drive with no known cause of this problem would be stupid, it would just happen again.

Computer Sleep Option Gone

Nov 19, 2013

I have had to do a complete reset of my computer recently and ever since I did that I have not had the option of putting my computer to sleep even after checking all my drivers to see if they are up to date. I am also having a problem where when I turn on my computer It will stay a black screen even though all signs point to it working just nothing shows on the screen. After a complete shutdown by holding the power button and turning it back on it works but doesn't let me get into BIOS.

Computer Won't Go To Sleep Plugged In

Feb 8, 2014

My laptop won't go to sleep when It's plugged in for some reason, though if I take out the power cable it will sleep. If I have the power cable out, send it to sleep then plug the power cable in this doesn't wake it up.

I've gone into the power option's but I'm not too sure what I can really change to make it work.

I've changed the multimedia setting's to allow the computer to sleep.

I've tried the different power plans - same behaviour.

Debugging :: BSOD After Or During Computer Sleep

Jul 1, 2014

Every few days my computer will BSOD when waking from sleep. The screen will display this message as the error "DRIVER_IRQL_NOT_LESS_OR_EQUAL cmudaxp.sys". Also sometimes the system will crash during sleep but no mini dump will be created. I have looked at the minidumps that were created and the only thing its pointed to were the cmudaxp.sys driver, hal.dll and ntoskrnl.exe. I tried reinstalling the drivers for the soundcard but that did not solve the problem. Today i reverted back to older drivers and will see if this fixes it. .dmp files included in attachment.

Computer Will Not Sleep Past First Time After Boot

Jun 29, 2014

I have a custom built computer running Windows 8.1 64-bit. Recently, it stopped going to sleep on it's own (except the first time that the power plan is followed after boot). Otherwise, the monitor goes to sleep and that is it. After a bunch of other attempts and fixes, I have found that there is a driver that is blatantly disregarding powercfg settings (as seen here: [URL] .....). This has been going on for over a week. I have run sfc /scannow, and dism /online /cleanup-image /restorehealth with no luck.

Debugging :: BSOD Waking Computer From Sleep?

May 15, 2014

I took my computer to a computer repairs to get my fan fixed and when I got it back I found that my computer kept crashing when waking from sleep. It happens every time and is inconvenient as it just resets. It also takes longer to turn on, it has a black screen for a short amount of time, it was not like this before, I can put up with the added turning on time but I need to be able to sleep and wake my laptop without issues.

Windows 8 - Sleep Won't Turn Off Computer After Set Time

Feb 12, 2013

The display and the sleep feature timers do not work. I just did a complete restore to try and correct this problem and another problem, which was no restore points and no ability to create one. The restore points are working for now, I mean that I was able to create a restore point. The display and sleep timer, not so, still a problem.

I've had this desktop Windows 8 computer since November and honestly I don't know if this has been a problem the whole time or not. Definitely, not the display, I know it has worked, but the sleep timer I'm not sure. I set the timer and just assume it sleeps and then goes into hibernation after a certain amount of time. With all the refreshing and restoring and changing over to this computer, I've not been paying much attention to the sound of the fan or the missing orange color on the power button (not visible, on the side of the computer).

I've set the timer through the Power Options feature in the Control Panel to 10 minutes for the sleep and to turn off the display to 3 minutes. Neither of them respond after set times. The computer is still wide awake and the display is not gone.

I have also gone to the "Change Advance Power Settings" menu box and turned off the hybrid sleep, which didn't work, and the Multimedia Settings in this menu box to turn on the setting "Allow The Computer To Sleep". Neither of these fixes did anything.

How can the computer not respond to something so basic and fundamental to its design?

Lastly, I'm wondering how this idea of powering down works at all. What I would like is for the computer to sleep after 20 minutes and then go into hibernation after 45 minutes. This would be when I'm done for the day. I have set the hibernation time in the "Change Advance Power Settings" menu box, but of course that does not respond either.

Computer Will Sleep But Stays Warm And Kills Battery

Aug 17, 2013

I recently bought a new Dell Inspiron laptop with Windows 8 (first time 8 user). I am loving the computer so far and don't mind Windows 8. It is not nearly as bad as people have told me, just takes getting used to.

However, I have had a problem when I put my computer to sleep. The screen shuts off and the power button blinks slowly like a slept computer would. However, the computer continues to feel as warm as it does when it is on and running. I also had it unplugged overnight after I put it to sleep, and in the morning, the battery had died, which shouldn't happen when it is asleep. I am far from an expert but I figure that while the computer goes to sleep, some program may still be running to keep using all that power.

How can I fix this problem because I need to transport my laptop around, but don't want to put it in an enclosed case if it stays warm while asleep?

After Upgrade To 8.1 Pro Computer Lost Ability To Sleep / Hibernate

Nov 2, 2013

After my upgrade to 8.1 Pro my computer lost the ability to sleep/hibernate. After following many tips on here, I managed to get sleep & hibernation onto the shutdown menu so manual operatin works okay.

The automatic mode is still a work in progress but I'm wondering if I've managed to get it to go into automatic sleep mode but not as yet hibernation.

I prefer to use hibernation so don't really know alot about sleep mode - I've got it configured to go into hibernation (10 minutes ) before sleep (15 minutes) in the power options.

After a period of time the computer will automatically attempt to enter either sleep or hibernation mode - not sure which. The screen switches off and the cpu increases in volume as if its consuming more power. The blue light flashes slowly which to me signifies that it has entered sleep mode. The computer has in effect shut down but sounds like its in overdrive with either the cpu or fan going ten to the dozen. Clicking the mouse wakes it up and brings it back to the sign-on screen.

So what's going on here? Is this a failed attempt at sleep mode as trying manual sleep brings the same result. It certainly doesn't go into automatic hibernation which is something I'm ultimately trying to resolve.

So I'm not sure if I've solved automatic sleep or not as its unbearably noisy and not something I can put up with.

Maintenance :: Computer Will Not Return To Sleep After Scheduled Task

Feb 23, 2014

Almost every morning for the last month or so I will discover my computer is running (monitor off, but computer not in sleep mode as it should be). To figure out what was waking it, I went to cmd prompt and used the command "powercfg -waketimers":

C:WINDOWSsystem32>powercfg -waketimers
Timer set by [SERVICE] DeviceHarddiskVolume1WindowsSystem32svchost.exe (Sys
temEventsBroker) expires at 4:01:43 AM on 2/23/2014.
Reason: Windows will execute 'NT TASKMicrosoftWindowsTaskSchedulerRegular
Maintenance' scheduled task that requested waking the computer. I also tried "powercfg -lastwake":


So it appears that "Regular Maintenance" is waking my computer. But why isn't it returning to sleep? It used to.

I then went to Power Options > Edit Plan Settings. These settings are still correct (Put the computer to sleep: 30 minutes).

Next I checked the Task Scheduler. Under "Active Tasks" I found "Regular Maintenance".

Next run time: 3:53 AM tomorrow. That very closely matches the 4:01 AM listed in "powercfg -waketimers", but I find it odd that it is after the scheduled time.

Triggers: At 3:00 AM every day

Doubling clicking on Regular Maintenance provides more detail.

Last Run Time: 5:46 AM

Last Run Result: operation completed successfully

However, another item in here is "Idle Maintenance".

Triggers: when computer is idle

Last Run Time: 5:46 AM

Last Run Result: The process terminated unexpectedly. (0x8007042B)

All of my drive partitions are scheduled to optimize weekly rather than daily. My computer is waking up daily.

Last night I turned all scheduled optimization off. This morning my computer was again woken from it sleep.

The cmd prompt gives me the same reason for the wake (Regular Maintenance).

Task Scheduler shows Regular Maintenance as:

Last Run Time: This morning at 4:36 AM

Last Run Result: The last run of the task was terminated by the user. (0x41306)

Under Idle Maintenance it shows nothing for this morning.

What does this mean? Optimization ran despite me turning it off?

Taskbar Options Lost When Reactivate Computer After Sleep Mode

Aug 28, 2013

Sometimes when my computer goes to sleep and I reactivate it some of my task bar options are lost

The date & display is no longer present neither is the volume control or my wifi display.

Also when this takes place I can no longer open any programs that are in the task bar I can simply click on them but nothing happens and when I attempt to open task manager it does not work I simply receive a black screen.

The only solution I have found so far is to restart and this solves the problem.

This is a new computer and I have only been using it for two or three days.

Acer M5811 - Unable To Wake Up Computer From Sleep Mode

Apr 2, 2013

My Acer M5811 will not wake up from sleep mode on intermittent basis. Running Windows 8 Pro 64 bit. Power settings are disabled for both the monitor and CPU. I have also disabled "allow computer to shut off applications to save power" to devices. I never had this issue until I installed Windows 8 (clean install) from Windows 7. I have updated all drivers but have had no luck. The computer will wake up successfully several times, then it will not wake up. It appears to start up but the monitor remains in sleep mode. The only way to fix the problem is to shut down the computer and then restart. Acer M5811, purchased May 2010; i760 processor; 8 GB ram, ATI Radeon 5570, 1TB hard drive.
