My iMac wakes up immediately after sleeping

First off, I'm using a mid-2010 imac with an i7 Quad Core processor, 8 GB 1333 MHz RAM, and Mac OSX 10.9.5.
I've had this issue for a while now and I seriously can't pin it down. It doesn't always do this - it seems completely random, where it will be constant for a few weeks, then it'll stop... then it'll start doing it again a couple months later. Basically, I put the iMac to sleep, and as soon as I can hear everything power off, it immediately wakes up. I've tried the following troubleshooting, to no avail:
*Disconnecting USB peripherals
*Turning off bluetooth mouse
*Disabling wake for network access
*Closing applications
Sometimes if I close my browsers (I primarily use Chrome and Firefox) it seems to allow the computer to sleep. Other times it doesn't. Sometimes I just have to shut down the whole computer to prevent it from keeping me awake at night. It's really frustrating. Anybody have any ideas?

Resetting SMC as well as NVRAM could solve the problem.

  • MBP wakes up immediately after sleep

    So my MBP has been waking up from sleep right after I put it into sleep mode for some reason.
    According to the console it's Wake reason: XHC1.
    After it wakes up to the login screen it then goes to sleep normally if I leave it, but choose apple menu - sleep makes it wake up every time right after.
    Some sort of maintenance thing or is it a bug?
    2012 15" MBP, ML 10.8.2 - all up to date.

    Hi Andrew,
    You've probably fix this by now, but I'm going to leave a reply for the benefit of anyone else who might be reading this. The XHC codes appear to have something to do with USB ports, so you'll want to check to make sure that you don't have any devices connected to the USB ports that might be triggering a wake. In my case, it was a hard drive docking station that was left on, but did not have a hard drive in it and was making no noise so I wasn't aware that it was on. I also wasn't aware that the hard drive docking station would be communicating so actively with my computer.

  • T530 wakes up immediately after it entered sleep mode or hibernation mode.

    My brand new T530 comes with windows8, but I found a strange thing that it can 't enter sleep mode or hibernation mode, every time it will wake up immediately even I close the lid.  The battery will be ran out in several hours.
    Anybody has same problem?

    Attempt to enter sleep or hibernation, then when it wakes up right after, go to Command Prompt and run "powercfg -lastwake". It'll tell you what woke up the system.

  • Sleeping PC wakes immediately after sleeping

    Hi guys,
    I have the bonjour SDK installed and have enabled wake for network access in the control panel, and it seems to be registering all of my services on my airport express correctly.
    My issue seems to be, that sometimes, not all the time, the PC wakes immediately after going to sleep.
    Obviously this is a pain as I want the PC to stay sleeping as much as possible to save on power.
    I have checked that I have no active connections to any services running on the PC, currently only windows file sharing, itunes sharing, and Plex media sharing are showing up as services.
    Is it likely that Bonjour is causing the PC to wake, or is it perhaps something else?
    Thanks
    Eds

    I have had the same problem you described for the past week. Very frustrating, also very dangerous. I got in from work today and my mbp had turned itself on with the lid closed, it was absolutely roasting hot, must have gone close to cooking it. Mine seems to be worse when its on power, did you guys notice any difference on power or battery?

  • MacBookPro / 15" / Intel i7 wakes immediately after sleep

    My new MBP (MacOS X 10.6.4) has been waking up immediately after I put the lid down, or select sleep from the Apple Menu. I have Boot Camp installed and Parallels 5, but I'm starting to suspect neither of those is the culprit. I wind up shutting the laptop down completely because it won't sleep. The issue occurs after four or five successful sleeps.
    Is this an isolated incident, ( calling for a re-install ) or is this a problem with OS X in general? It seems the problem cropped up after installing system updates. Is there a specific update causing this?
    Thanks!!

  • Unable to turn imac on or off after sleep mode

    I have a fairly new iMac and I installed Leopard yesterday. When the computer goes to sleep, I am unable to get it back on by either pressing the keyboard or the power button. The only thing I can do is to unplug and re-plug the computer. When the computer comes back on, I get a message that OS X unexpectedly was interrupted, so I know the operating system is still running in the background.
    Has anybody else had this problem or can recommend a solution. I now set my preferences so that the computer will never go to sleep.

    I have a similar problem of "video freeze" on my 1.67 GHz PowerPC G4 15 inch with an Apple 21 inch display attached. The large display is exclusive since the powerPC is run with the display lid closed.
    Upon wake up after sleep, the video screen stays black, but I hear disk noise in the background indicating some level of 10.5 operation.
    The only recovery I've found so far is to open the display lid on the PowerPC and press the power key until reboot.

  • Windows 8 wakes up IMMEDIATELY from sleep.

    Hi! I'm happy user of Windows 8. OK. I'm not fully happy... In installed Windows 8 and it worked great, for some time. After SOME updates my computer will not sleep for more that 20 sec. It will ALWAYS wake up. When I didn't clean installation of Windows
    8 this problem didn't appear.
    No any setting were change in my computer from "before to after" updates. 
    Can anybody can help?
    I checked MANY of thinks from discussion forums, none of them helped. 
    BTW. I'm not sure if this question is in right forum category.

    Hi,
    I actually have the problem where my computer wakes from sleep at 8:55 am every morning. I've done all the command line stuff mentioned above and according to Windows there is nothing enabled to wake my system from sleep, neither hardware nor a scheduled
    task. My event viewer just shows an "unknown" wake source. I have a Samsung laptop, so I began suspecting it was some Samsung proprietary process doing this, but the specific things mentioned here, SSD and Magician, don't appear to be installed on my machine.
    When I look at Programs and Features in the Control Panel, those programs are not listed. If I had them installed they'd show up there right?
    Also I booted into BIOS to see if there was something in there that could be waking the computer. The only relevant option was a wake from USB, but that was disabled already. There was no other option in there.
    Does anybody have any idea what could be doing this?
    Another related problem is that Windows keeps forcing the Power Saver power mode on me. No matter how many times I change to the Balanced or High Performance plan, it keeps reverting to Power Saver.

  • Wireless connection not restored immediately after sleep

    Hi,
    Since I have updated to Mavericks (OS X 10.9.1), my wireless connection doesn't restore automatically anymore after sleep.
    This recently also started to happen when I boot my computer. I always have to click the wifi icon, select my network and then it still says "can't connect to network".
    When I click the wifi icon and select my network a second time, it works.
    I have tried setting the order of network services (WiFi first, then Bluetooth and finally Thunderbolt bridge), deleting my saved home network and adding it again, deleting all other saved wireless networks.
    What can I do to fix this?
    Thank you.

    Test after taking each of the following steps that you haven't already tried. Back up all data before making any changes.
    1. Make sure the network is on the preferred list by following these instructions. It's important to read the article carefully, as it's the starting point for any further efforts to solve the problem. If you skip any of the steps, the problem may not be solved. Make sure the box marked
    Remember networks this computer has joined
    is checked.
    2. Follow the instructions in this support article under the heading "Symptom: The network connection drops unexpectedly."
    3. Make a note of all your settings for Wi-Fi in the Network preference pane, then delete the connection from the connection list and recreate it with the same settings. You do this by clicking the plus-sign icon below the connection list, and selecting Wi-Fi as the interface in the sheet that opens. Select Join other network from the Network Name menu, then select your network. Enter the password when prompted and save it in the keychain.
    4. From the Location menu at the top of the Network preference pane, select Edit Locations. A sheet will drop down. Click the plus-sign button to create a new location. Give it any name you want. In the new location, set up the Wi-Fi service with the same settings you used before. Click Apply and test.
    5. Launch the Keychain Access application. Search for and delete all AirPort network password items that refer to the network. Make a note of the password first.
    6. Repair permissions on the startup volume.
    7. Turn off Bluetooth and test.
    8. Reset the System Management Controller.
    9. Reset the PRAM.
    10. Reinstall OS X.

  • Computer now wakes up immediately after I put it to sleep!!

    I've got a dual G5 running Panther and I put it to sleep when I go to work in the morning. Last night, I wanted to try out Tiger (yes, I know - I'm way behind the times) so I installed it on a FireWire drive and booted off it for a couple of hours to see how things worked. I then went back to my internal Panther drive, and everything is ok except for one thing: when I hit "sleep", it goes to sleep, the screens turn off, and then for some reason I immediately hear the internal drives spin back up and the thing turns on again!! Why can't it stay asleep?!?

    Sleep is one of the activities controlled by the PMU. A reset of the PMU may
    be in order:
    http://docs.info.apple.com/article.html?artnum=86760
    what settings will be cleared by this (what will I lose and need to set up again)? any system Settings, firmware updates, or whatever?
    Also, I trust that you have reviewed your Energy saving preferences to confirm
    that they are set to allow sleep, and not to disturb said sleep?
    which ones in particular? I think they're fine but maybe I'm missing something that got munged somehow. Where are the "disturb"-type settings? I've got "wake on LAN access" clicked off for example. What else is there?
    Thanks,
    Mike

  • Hard drive wakes up immediately after being put into standby

    I have an IDE disk which, till now, I used to keep in standby mode (it makes an audible humming noise when it's working which annoys me a lot :<). Today I noticed that after running `hdparm -y' on it, it would spin down but then it would immediately spin up again. I'm certain that the disk isn't being used and doesn't have any partitions mounted anywhere on the filesystem. Still, I'm unable to pinpoint the reason it's waking up.
    Any ideas on why this is happening?
    Edit: It appears that the disk gets into standby by itself after 10 minutes. I wish I knew where this value is coming from. O.o
    Edit2: Those 10 minutes must be coming from `hdparm -S1 /dev/sdb'; maybe the hard drive has a lower limit in regard to this setting. :3
    (I'm not sure what kind of information would be useful in order to troubleshoot this issue, but below are some bits I believe are relevant)
    Failed attempt to put the drive into standby:

    Here is what i get when i try that command.:
    $ sudo hdparm -B 254 /dev/sdc
    /dev/sdc:
    setting Advanced Power Management level to 0xfe (254)
    HDIO_DRIVE_CMD failed: Input/output error
    APM_level = not supported
    I tried other values also and its always the same error.
    I just did another try with -y and the drive stayed in standby during ±40 minutes this time. The most annoying part is that is something that was not happening before I am pretty sure that it would stay in standby for days.
    I also included my results for hdparm -I.:

  • When i try to wake my macbook after sleep the keypad lights up but the screen stays black. I have to switch off and restart. How do I fix this?

    After my Macbook goes into sleep mode it sometimes won't wake. The keypad lights up but the screen stays black. This problem has only occured after updating to OSX 10.7.2.
    All I can do is switch off and restart. Then any programs I have not 'quit' all open.

    OK, I have a fix. 
    After spending about an hour online with Apple Care without success, I did a reinstall of the Lion OS. It fixed the problem.  I was concerned that I would lose data or settings, but the reinstall was seemless and everything was the way it was before the reinstall except that the "black screen on wake" problem was fixed.
    I started the reinstall before I went to bed and it was waiting for me the next morning.
    Here is a link to the page on how to do the reinstall:

    Hope this helps.
