Sleep mode not working after iMac WLAN Update 1.0

Hello,
unfortunately the sleep mode isn't working anymore after the latest "iMac WLAN Update 1.0" update.
Usually I press cmd+alt+eject to activate the sleep mode, since the update the screen switches off (black) for a second and immediately turns on again. Fans and HD keep running without any interruption.
Same behaviour if I use the "sleep mode" command from the Apple menu, except the screen turns off and keeps off, but fans and HD are still running.
The iMac never activates the sleep mode by itself (e.g. after 15 minutes), this also a new "feature" which occured after the update.
Is there anyone recognizing the same problems? Any hints how it can be solved?
Thank you very much in advance,
Oliver

I finally found the solution in a German newsgroup. First: It has nothing to do with the "iMac WLAN Update 1.0" .
A unsuccessful printer job caused the problem and just open the CUPS site http://127.0.0.1:631/jobs and delete the hanging job solved the problem!
Thanks,
Oliver

  • HT1338 early 2012 macbook air clamshell mode not working after mountain lion update

    Can't make 2012 MBA 13" work in clamshell mode after updating to Mountain Lion.  All peripheral devices are connected, as is AC power.  Closing lid causes external monitor to enter sleep mode (presumably, the MBA is going to sleep as well).
    Power settings are set to stay awake when on AC power.
    Thank you.

    Hi,
    The two may be linked as there is a common support app called IMAgent that helps with both Messages and FaceTime.
    Shut down both apps.
    With the Finder as the Front App > use the Go Menu > Hold down ALT key and select Library.
    In the Library find and open th Preferences Folder
    Find com.apple.IMAgent.plist and drag it to the Trash
    Before restarting the App now go to Activity Monitor in Applications/Utilities.
    Find imagent (it  is in lower case).
    Highlight and use the Quit button.
    Now restart the app(s).
    This will recreate the .plist  from defaults.

    - Try resetting the iPod. Nothing will be lost.
    Reset iPod touch:  Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Download/install a new app
    - Restore from backup
    - Restore to factory daults/new iPod.

  • HT201366 CAC readers not working after installing security update 2013-003?

    Is anyone else having problems with CAC readers not working after installing security update 2013-003? CAC required websites are causing safari and chrome to crash.

    For CAC issues, see:

    Please follow these directions to delete the Mail "sandbox" folder.
    Back up all data.
    Triple-click the line below to select it:
    ~/Library/Containers/com.apple.mail
    Right-click or control-click the highlighted line and select
    Services ▹ Reveal
    from the contextual menu.* A Finder window should open with a folder named "com.apple.mail" selected. If it does, move the selected folder — not just its contents — to the Desktop. Leave the Finder window open for now.
    Quit and relaunch Mail, and test. If the problem is resolved, you may have to recreate some of your Mail settings. You can then delete the folder you moved and close the Finder window. If you still have the problem, quit Mail again and put the folder back where it was, overwriting the one that may have been created in its place. Post your results.
    Caution: If you change any of the contents of the sandbox, but leave the folder itself in place, Mail may crash or not launch at all. Deleting the whole sandbox will cause it to be rebuilt automatically.
    *If you don't see the contextual menu item, copy the selected text to the Clipboard (command-C). In the Finder, select
    Go ▹ Go to Folder...
    from the menu bar, paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return.

  • HT4623 Anyone having trouble with App Store install and cloud store buttons not working after 6.1 update?

    Anyone having trouble with App Store install and cloud store buttons not working after 6.1 update? I go to install an app. I hit install and nothing happens. About a minute later it asks me for my password and then it does nothing. The install button goes back to saying install. However the app shows up in my installed list and in cloud but no app installed.

    OK - I found a helpful post - closed app store app and under Settings/General/Date and Time I reset the date and time by switching off "Set Automatically" and then switching it on again. Went back to App Store, launched it and Updatesseems to be working again.
    Go figure? Logical, No!

    windows 10 sleep mode not working

    I hope this helps. But... I had the same problem last week. Now I don't as of 8/17/15. I am not sure if a windows 10 update fixed this. I do not like problems that without any assistance fix themselves. However, try sleep mode again. This problem may have been fixed.

  • HT6154 rear camera on iphone 5 not working after ios 8 update why?

    My iPhone 5 rear camera is no longer working after ios 8 update its just black I can see the flash choice the hdr and the timer but other than that it is a black screen

    Hi there fjci2003,
    You may find the troubleshooting steps in the article below helpful.
    Get help with the camera on your iPhone, iPad, or iPod touch 
    You see a closed lens or black screen
    If you see a closed lens or black screen when you open the Camera app, try these steps:
    Make sure that there’s nothing blocking the camera lens. If you’re using a case, try removing it.
    Force the app to close, then open the Camera app again.
    Restart your device, then open the Camera app again.
    If your device has a front and rear camera, try both cameras by tapping the camera swap icon . If you see the closed lens or black screen on only one camera, take your device to an Apple Retail Store or Authorized Service Provider for more help.

  • My sound system is not working after my last updates on my imac,what shall i do to get fixed?

    Hello any body who can help me out here?
    My sound system is not working on my imac after the last updates,
    WHAT SHALL I DO FOR????

    apollos211,
    You marked this as solved, so chances are no one else will respond.
    You can try going Applications>utilities>audio MIDI set up, output tab and check to see if built in is selected.
    Also check in system preferences>sound >output and see what is selected there.
    If you look in the headphone port and see a red light (this means it is in digital mode), try taking a set off headphones and plugging them in and out several times also wiggle them around gently. There is a micro switch that sometimes gets stuck.
    Hope this helps, if still no joy try reposting so that more contributers might check it, as once checked as solved it reduces the number of people checking.
    All the best

  • Airplay is not working after the last updates

    Hello,
    I've updated iphone, ipad air and ipad 4 to ios 8 and apple tv 3 (1469) to newest version (7?).
    After that it's absolutely a disaster.
    Mostly I using the apple tv for music streaming, sometimes for mirroring...
    But it can not be found, I can not select the apple tv on ios devices because it is not there!
    The airplay symbol comes after swiping the menu up after approx. 1 sec and theres only the Denon Cocoon to selcet but not the apple tv.
    The same on the iMac I can not choose the apple tv directly from the top bar for mirroring and not in itunes for music streaming (but the Cocoon is there), and this altough the imac is also via ethernet on the same router, no wlan connection is required for streaming in this case.
    The apple tv is connected by ethernet to the router and I see in the router menu that the apple tv is connected to the internet.
    I did a hard-reset but this did not help.
    I've tried also with blutooth on or off and rebootet the ios devices.
    From time to time one of the different devices shows the apple tv...this morning for example after I turn blutooth on at the iphone and waited 30 seconds, it was there and it worked - sometimes on device shows the apple tv without blutooth and if I connect, nothing happen and the music starts on the device itself.
    If I start the apple tv via remote, everything is fine, I find it at all devices including the imac!
    If I managed it to start the music streaming with an device (as written, from time to time it works) the apple tv is avaible on all other devices.
    For me theres no question that theres a bug in the new apple-tv software (because I can not find it on the imac as well, otherwise I would think the bug is in ios 8).
    It is not possible to wake up the apple tv via airplay from sleep mode, I think that is the problem - if I turn off the sleep mode everything is fine.

    Nothing unusual in that after an update.
    Generally speaking it's fairly obvious from the volume of such posts if there's a problem with an update or not. On this occasion I'm not seeing the sort of numbers that indicate a widespread issue.

  • Yoga 2 830lc wifi not working after android 5 update

    hi i am update my yoga 2 830lc to android 5 and after update not working wifi please help me

    Hello all. Fisrt of all, this are my specs: Yoga 2 pro 13". WiFi card: Intel(R)Dual Band Wireless-AC 7260. I bought it from Best Buy on November 27, 2014. If you aquired your Yoga before this date, you may have the single band WiFi card. As many of you have experienced, I also had a bunch of issues with my WiFi connectivity and this is how I was able to solve it. At least it has been a couple of days that I haven't had any issues. The first symptom was the usual connection drops every X amount of time. For me it was about every 2 hours. I first unchecked the "Allow the computer to turn off this device to save power" option in the Power Management tab of device manager and disabled U-APSD support in the Advanced tab of device manager. This action did not solve the problem. I then downloaded and updated the driver from the Intel web site (http://www.intel.com/p/en_US/support/detect) and this seemed to solve the drops; however, a new problem arised: Everytime my Yoga would wake up from sleeping mode, all my wifi networks were gone and the adapter showed as disabled in Device Manager. I would have to anable it to have my networks back. It was a solution but a pain the butt to have to do this everytime. After hours of reading post after post in several forums, I read a repy from Lenovo asking to try leaving the "Allow the computer to turn off this device to save power" CHECKED if you were using the latest version of the driver. I went back to device manager and checked it back and that seems to have solved the problem. So far I haven't had any drops and everytime my laptop comes back from sleeping mode the WFi connection is still there! Here is a recap of how everything ended up: -The driver version I installed is 17.1.0.19-The driver date is 7/21/2014-In device manager|Advanced, U-APSD support is Disbled.-In device manager|Power Management, "Allow the computer to turn off this device to save power" is checked. Hope this helps somebody else.
