HELP! My iMac freeze when awaken from Sleep mode

Its unusual... I think its because of the updates. I have the latest version of Leopard. Can anyone help? I hate to reboot my machine as i heard its not good to do often.

Hello xoxo:
That is not normal.
This article will explain how to reset the System Management Controller (SMC):

If that does not help, I would take the computer to either en Apple store or to an Apple-certified technician for diagnosis.

  • Macmini 2011 on lion, goes to a blue screen om monitor when awakening from sleep mode, last 3 or 4 seconds, can anyone help? Thanks

    Macmini 2011 on lion, goes to a blue screen on monitor when awakening from sleep mode, last 3 or 4 seconds, before desktop appears, can anyone help? Thanks

    Depending on the system configuration, this may not
    be unusual.  The Mini that I use for my home theater,
    which is connected to a receiver then to a TV, all via
    HDMI usually takes a couple seconds to come up just
    the way yours does.  Same happens when I switch sources
    on the receiver.  Actually, it starts with the blue screen and
    will sometimes flash before the desktop comes up.
    It seems that when HDMI goes dormant, there is handshaking
    that needs to be re-established, at least thats my SWAG on it.
    On the other hand, the Mac Mini Server that I use as a work
    station and is connected to a Thunderbolt Display, wakes to desktop
    in a second, maybe two.  On this combo, it just comes up to
    the desk top.
    It also probably depends on what processes were active when
    the Mini was put to sleep.  So it may take some time for it to get around
    to reloading the desktop.

  • Helix freezes when resuming from sleep mode

    Every time I close the lid, the Helix enters sleep mode. Then, when I reopen it and enter my password, the computer freezes, most often taking me to the Photos app.  In order to resume work, I have to use the Power button to shut down and restart.  Very frustrating -- can't even walk across the room with the lid closed without having to restart, often losing whatever I was working on.  Any ideas?

    Hi Yvonnerose,
    Thank you for the reply!
    1) Update your bios and update the Intel Management Engine firmware to the latest. Below is the link to enter the downloads page and download latest application accordingly, please click on "Select Product" then in "QUICK PATH" enter the MTM no. select the exact model.
    http://support.lenovo.com/en_US/downloads/default.page#
    2) if issues still persist, please check the installed RAMS or he secondary RAM installed as in some cases it has been found cause the interruptions. If the system is shipped with dual memory try running with only one RAM first to check if problem still persist.
    3) If both of the above fails please contact nearby Authorized Lenovo service support teams, they will able to advise according on the next course of action.
    Hope this helps. 
    Best regards,

  • Yoga 2 Backlit Keyboard resets to "Off" when awakening from Sleep mode?

    My Yoga 2 turns its backlit keyboard off when it goes to sleep and awakens . . . is there a way to set it as always on?  

    The fan seems to be running alot as well and the MBP isn,t that old only 6-7 months at the outside , could it be anything else possibly or do you definately think it is the Crashing issue

  • Since updating to Lion the iMac won't recognise the external hard drive (maxtor) when waking from sleep mode,

    Hi All, Since updating to Lion, my imac won't recognise the ext HDD (Maxtor) when waking from sleep mode, I have tried another port, diisc utility (Ext HDD not listed in here) but nothing works. I now find that I have to restart the imac to get the drive recognised..which is fine until the imac goes into sleep mode then I lose the drive and have to restart etc etc.....anyone suffering same issue.  The Ext Drive worked perfectly until the upgrade..

    Thanks for this, and apologies for delay in replying...in between seeing your post I backed up the ext hdd to another mac and used the disc utility to erase and repair and then re mounted the ext hdd. OK.  I have then tested the ext hdd being recognised when waking from sleep mode a few times and everything appears to be fine. If this doesn't work (long term) I will follow the instructions as you have suggested....
    I now have a new problem with my HP printer (Photosmart Plus) which is not being recognised by a new wireless router..Ok whilst the router is switch on and I have reconfigured the printer..but when the router is switched off overnight and then switched back on...I get a 'printer is not connected' message and have to go through the re configure routine all over. I am minded to think this is a router problem as the same issue is happening to my wifes Mac Book Pro (which is only a few weeks old)...any suggestions..

  • Spinning beach ball when awakening from sleep

    I get the spinning wheel when awakening from sleep. Also my fans seem to be running a lot more than they used to.  I've tried resetting SMC and PRAM.  I recently installed a Crucial 256GB M4 SSD and enabled TRIM--not sure if that had anything to do with it.  Running OS X 10.7.4 and have the latest updates. This is on an early 2011 MBP with 16GB RAM.
    Anything I should do or check?
    Thx

    Seems to be a problem with the hard drive. Ok prior to 10.5.2. Affected drive: Fujitsu MHV2100AT PL 100gb

  • Kernel Panic when waking from sleep mode., Kernel Panic when waking from sleep mode.

    Hi,
    I have an Imac 2.8 GHz Intel Core 2 Duo desktop which I have upgraded to lion.
    Recently I keep getting kernel panics when waking from sleep mode and I cannot figure out what it is.
    I am not very computer savy - I.e. I use a computer but don't know programming etc.
    The computer then asks me to shut down and restart.
    Any help would be much appreciated as this is driving me crazy.

    Hi, for other peoples information - I finally figured out the problem. It was actually a faulty RAM module which I had bought. I had upgraded from 2 to 4 gb of RAM using an approved type of RAM for my particular computer. Finally I removed one module of RAM (after doing nearly everything else under the sun including trying to reinstall the operating system and wipe the computer etc) and the computer worked fine.

  • Wifi disconnects when waking from sleep mode; running Mountain Lion

    Had this same issue with Lion as well,, wifi disconnects when waking from sleep mode,,,any ideas how to fix this pesky issue?

    Hi Sky,
    This has worked for a few...
    Make a New Location, Using network locations in Mac OS X ...
    http://support.apple.com/kb/HT2712
    10.7…
    System Preferences>Network, top of window>Locations>Edit Locations, little plus icon, give it a name.
    10.5.x/10.6.x/10.7.x instructions...
    System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.
    The interface that connects to the Internet should be dragged to the top of the list.
    Instead of joining your Network from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed.
    For 10.5/10.6, System Preferences>Network, unlock the lock if need be, highlight the Interface you use to connect to Internet, click on the advanced button, click on the DNS tab, click on the little plus icon, then add these numbers...
    208.67.222.222
    208.67.220.220
    Click OK.
    Also, turn off IPv6:
    System Preferences » Network » AirPort » TCP/IP tab » Configure IPv6
    Or whatever Interface you use.

  • Firefox crashes windows 7 when recovering from sleep mode

    Similar to the following:
    http://support.mozilla.com/pl/forum/1/627872?s=window+7+crash&as=s
    but not sure whether it depends on pages that are currently opened.
    Sometimes, when recovering from sleep mode on win7 (with only Firefox and VS2008 running), win7 crashes. What's important - It doesn't happen always, but still, it's annoying (Firefox starts with startpage only).
    I've been noticing this issue on different Firefox versions from Firefox 3.5 to 3.6.6.

    Same exactly problem here, very annoying when the computer goes to sleep mode and then Firefox locks up.

  • Freezing when waking from sleep with latest Lion release?

    I have had both my IMac and MacBook Pro freeze upon waking from sleep recently. Occurred only after installing latest Lion upgrade. Very frustrating since requires hard reboot ronin case of the MacBook Pro, reinstalling the OS. I have noticed similar complaints by others. Any suggestions for a fix other than waiting for a new release?

    Launch the Terminal application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Terminal in the page that opens.
    Drag or copy – do not type – the following line into the Terminal window, then press return:
    pmset -g
    Post any lines of output that appear below what you entered – the text, please, not a screenshot.

  • MBP 2010 13'' completely freezing when loading from sleep after battery drain

    Hi all,
    Ever since upgrading do Mountain Lion, everytime my MBP 2010 13'' goes to sleep after battery drainage, it freezes in the last "dash" of the waking up process. Furthermore I noticed that the background during wake up is not my dimmed desktop anymore as it used to be on Lion, it is the Apple logo on a white background (similar to Power up screen). I experience no other freezing stated by the community that are attributed to ML, iTunes or Safari, only this one when recovering from sleep. This last time I waited a couple of hours before power down, only resulting in abnormal heating. Already tried fully charge, fully recharge, reboot, cmd+opt+p+r, ... Anyone has this? Is it a known problem being somehow addressed by Apple? Thanks in advance!

    So can anyone tell me how can I open an issue on this for Apple? Thanks.

  • Freezing upon waking from sleep mode

    I'm having a freeze issue with my imac. When I go to wake it up from sleep mode it wakes up, but then immediately freezes. Sometimes the dock items will still magnify, sometimes not. Sometimes the whole system will eventually wake up and open whatever program I was trying to open, but it takes upwards of half an hour. I used the techtool disc and it showed no hardware issues. Any help would be greatly appreciated.

    Please try resetting the PRAM

    and also the SMC

  • IMac hangs waking up from sleep mode, what can I do?

    I have an iMac - early 2008, Inter Core 2 Duo, screenshots of full specs attached below.
    I upgraded to Mountain Lion about 3 weeks ago. No problem until 2-3 days ago when the iMac started to 'hang' after waking up from sleep mode.
    I'd try to launch Safari but the icon just bounces on the dock.
    Force quitting all open apps, force quitting Finder. Still nothing.
    Can't shut down unless I hold the power button down.
    Then on restart it says something about an application that was previously unresponsive...try to reopen it or wait 50 seconds (or thereabouts) - I choose the latter option.
    I've tried to do the usual verify/repair permissions and verify/repair disk. No problem found.
    Incidentally, this has only been happening since 'upgrading' to iTunes 11. Coincidence?
    Can someone help?

    Ok, I've done everything suggested above except for running the Disk Utility from the recovery partition, as I will have more time to spend on it tomorrow and that's something I'm too scared to try in a rush....!
    I've made a screenshot of the energy saving settings changed to your suggestion, could you let me know if that's what you meant?
    I really appreciate your help by the way

  • BT Keyboard Loses Connection When Waking from Sleep Mode

    I'm running Windows 7 on a late 2009 27" iMac and my Bluetooth keyboard keeps loses connection when I wake my computer from sleep mode. Usually the only way I can get it back is my resetting. Anyone know of a way to fix this? Any help would be great appreciated.

    If the MBP doesn't wake when you open the lid but does when you press any key afterward, do this:
    Applications > Utilities > Terminal
    Copy and paste the following text in the Terminal window:
    *sudo pmset lidwake 1*
    You'll be asked for your admin password. Type that in (Note: the password will not be displayed as you do so). Press Return, and quit the Terminal. Close the MBP, wait for it to sleep, and open it again. Does it wake now?
    If you want to change it back so the system doesn't wake when you open the lid, repeat the procedure, but this time type or paste:
    *sudo pmset lidwake 0*

  • Sound not staying muted when resuming from Sleep mode

    The subject says it all. When I resume from Sleep mode the sound is not staying muted. I have found a third party app to get around this but I would rather solve it without having to run something else in startup.
    I have a HP Pavilion dv7-2206tx Entertainment Notebook running Windows 7 with all the latest updates installed.
    Anyone know how to prevent this from happening?

    cfr is a regular presence around here and helps quite a lot of people.  He was trying to get clarification so that your problem could be further debugged.  You may think that his statements are "lame ass" but you attitude is "asshole".  Don't come here looking for help and then tell those trying to help you that their help sucks.  If that is how you show your appreciation for support, you should go elsewhere.
