Sleep light not "pulsing" when in sleep mode

Hey guys, i have a little problem with the sleep light... i don't know when this started, but i notice today, that when i put my macbook pro to sleep, the light just stays on and not "pulsing" like it used to do... is that normal?
How can i fix this?

This usually happens when you might have an application which is still running and is failing to quit. Check Activity Monitor for a list of all your processes.

  • Solid sleep light - not pulsing

    Didn't want to just tack this onto another question, and I didn't see any answers when I searched here, so I hope no one minds another thread.
    What does it mean when the sleep light stays on, but doesn't pulse like it does when it's sleeping? The only reference to the light at all in the manual is about it pulsing when the computer sleeps. We had a day when the light just stayed on solid after we (supposedly) shut down. I think we just figured it was in some standby mode, but in searching here, I'm betting we didn't let the computer shut down totally, because we had a heck of a time restarting it.
    All's well now, and there seem to be no other issues (yet), but you'd think there's be some reference to the light staying solid in the troubleshooting section of the manual. I hope we didn't do any damage, but as I said, it's been running fine since. Has anyone else seen a solid glowing light?

    If the light is on constantly, but the screen is
    black, then the screen is asleep, but the computer
    itself isn't, formerly Don.
    The most probable cause is that you shut the screen
    before shutdown of the computer had completed, but
    there can be other reasons for a failed shutdown.
    Its a good idea to keep an eye on such things,
    because you can end up in a situation where, for
    example, the procesor is still running when you put
    the computer in a bag, with consequent heat issues.
    As far as starting new threads go, go for it. Unless
    your problem is clearly and obviously addressed by
    another thread its actually a very good idea to start
    a new one for your own particular problem. Otherwise
    things can get very confused when posters are trying
    to help out more than one problem sufferer. Often
    what LOOKS like the same issue to the original poster
    may turn out to involve something quite different,
    and its easy to get lost in the ensuing confusions.
    Cheers

    Thanks. The MacBook was closed, so I can only assume the display was asleep. I'll bet you're right, though, and we just closed the lid before it finished shutting down. Since then I've been so paranoid, I've been waiting a good 20 seconds after the screen goes dark before closing the lid. I sure can't hear anything happening even with my ears right up to the vent.
    And thanks for making me feel better about the new thread. Some forums get touchy about such things.
    BTW, the only reason I'm formerly Don G. is because for some reason when I logged into my account, it made me go through the sign up page again, and said there was another user already with Don G. No kidding. That's me!

  • Since I installed Lion on my macbook the LED light does not pulse when I close the screen - the sleep function does not work.

    Since I installed Lion on my macbook the LED light does not pulse when I close the screen - the sleep function does not work neither when chosen after pressing the button nor chosen in the apple menu..

    I have had the same problem but on another forum it was suggested that disabling internet sharing would solve this. This fix seems to work on my machine - why it works I do not understand

  • ACD sleep indicator light not pulsing

    I installed Windows Vista Home Basic on my Mac Pro yesterday. My display is a 20" ACD (aluminium).
    Since this Vista installation, the indicator light on the ACD does not pulse during sleep, but remains on steadily. The front indicator light on the Mac does pulse as normal during sleep.
    In both instances, this indicator light is off as normal on both the Mac and the ACD while the Mac is being used.
    Is this an issue others have seen, and does it have any negative indications?

    In Displays/Option, the Display Power Button preference had been set to 'Turns the display on and off' and this had caused the problem I described earlier. I am not sure why this option had been selected after the installation of Vista yesterday, because I didn't open Preferences during or after this installation.
    I have now changed the option to 'Puts the system to sleep or wakes it'. This is the option I normally use and I was not actually aware it caused the display sleep light to pulse.
    The display has now returned to the more usual state (for me) of gently pulsing.
    Thank you, Malcolm, you have been very helpful.

  • Phone not ringing when in sleep mode

    Over last few days have had problem with iPhone 4S not ringing when in sleep mode. I have just spoken to Apple support. I had do not disturb scheduled , but this was staying on all the time , which I hadn't realised. This is a fault which should be sorted by 7th Jan. hope this helps anyone else with same problem, as I did search this site first.

    This is the exact problem i'm having right now, I don't know why it's happening, but when i have it on the desk and when it's in sleep mode, I can get phonecalls and it won't ring but it won't show up as missed calls either, if i get a voice message i'll get it if i take it out of sleep mode and let it sit with full reception for a minute.
    I also lose all reception while in sleep mode.

  • OS X Lion: Fix for wireless not reconnecting when exiting sleep mode

    http://www.tech-recipes.com/rx/18931/os-x-lion-fix-for-wireless-not-reconnecting -when-exiting-sleep-mode/

    I have the same symptoms with a 2011 iMac and my Senheiser Bluetooth headphones.
    10.7.3 did not correct this bug.
    I'm also using MS Messenger and notification sounds are also buffered until the headphones are switched on.
    I found other threads dealing with this bug :

  • Battery not charging when in sleep mode

    This might sound like a dumb question but, is it normal that my shuffle does not charge when computer is in sleep mode? It's been plugged in for the last 6 hours and the amber light is still flashing. Can I change the sleep mode on my computer? surely I don't have to be working at my computer for 4 hours every time I want to charge the shuffle. thanks
    G5   Mac OS X (10.4.3)  

    You can also change your SysPrefs so that the Mac doesn't go into Sleep when you don't want it to .... for example, when you want to charge the iPod. You won't lose much by doing this; it can still be set up to shut down the display and your hard drive.
    My own preference these days is to disable automatic sleep completely. If I wind up leaving for a few hours or an afternoon, I don't mind leaving it in the 'near sleep' mode that it goes into and even that happens only when I overlook putting it to sleep manually. You can do that with the remote, with the power button, or of course via the Apple Menu.

  • SLEEP LIGHT NOT BLINKING

    Hello All,
    I have had my black Macbook for almost 4 years now. Recently, when my computer is in sleep mode, I noticed that the sleep light is not blinking. It isnt even coming on. It seems to be sleeping and nothing is running, its just that the light does not come on. What does this mean? I wanted to know what I could do to solve this problem. Any help would be appreciated!
    -J

    As it sounds like sleep is working properly and just the indicator is not flashing, try resetting your System Management Controller:
    http://support.apple.com/kb/HT3964?viewlocale=en_US
    If you scroll about half way down the above page, you'll see the types of things that resetting the SMC may cure (generally power related). Just be sure to follow the instructions for your particular machine as they vary from machine to machine.

  • Sleep light not coming on

    Hello, I have a late 2006 Black MacBook, and I have noticed that the sleep indicator light does not come on unless I press on the top cover in that corner. Is this a loose connection that I can fix, or is it something that I need to replace?

    There is a small ribbon cable from the sleep light and remote control sensor, and it is possible that it could be loose where it joins to the hard drive connector. As this connection is incredibly small and delicate, and can only be accessed by removing the keyboard/topcase, hard drive and connector, it would probably be best to leave it as there is a risk of causing more serious damage.

  • QS 2002... SLEEP ISSUES NOT COME UP AFTER SLEEP PERIOD

    QS 2002... SLEEP ISSUES NOT BOOTING UP AFTER A SLEEP PERIOD
    Any ideas

    I was thinking you could offer a little bit more detail.
    If your Mac happily goes to sleep but won't wake up--Hold down the power switch to force-reboot your machine and get it running again.
    Don't worry-your Mac isn't narcoleptic. Its Open Firmware system or NVRAM (nonvolatile RAM) is likely corrupt, and your Mac can't remember how to wake up.
    Try resetting the PRAM. This should reset the NVRAM on most machines, which is the suggested fix. If that didn't help, do the following manually;
    Restart your Mac and immediately hold down the Command-Option-O-F key combo until you see a somewhat intimidating command-line display that ends with the Open Fimware prompt. Type the following line:
    reset-nvram
    press the return key on your keyboard
    set-defaults
    press return
    reset-all
    press return
    Your Mac will reboot. Once it's running, put it back to sleep to test. If the problem recurs your Energy Saver preferences may be the culprit. Delete the com.apple.PowerManagement.plist file (go to Finder/Hard drive/Library/Preferences/SystemConfiguration)--don't worry, your Mac will regenerate a new one--and then restart to see if that rights the wrong.
    If you have a storage device mounted via a PCI card that doesn't support sleep read this Apple doc. Thanks Texas MacMan!
    Still didn't work? Might be time to call AppleCare or see an Apple Genius or a technician.
     Good Luck! DALE

  • Macbook not starting when in sleep mode

    So my white 13 inch macbook was in sleep mode for a couple hours and usually I just press either the enter/return button or the power/startup button to wake the computer but for the past two times, it wasn't starting up unless I held the power/startup button until it completely turned off. I then had to completely restart the computer. And that was the only way I could get it to turn on. In the past, like I said, everything worked fine when I hit the enter or power button. Has this happened to anybody else's macbooks? I guess from now on I'll pretty much always have to shutdown the mac completely when not using it.

    HI,
    *"Will it wipe the hard drive? Will I lose files? What will change exactly*
    If you read the material at those links it explains everything. It's very simple. It won't wipe the drive or lose files.
    SMC: "As the name implies, it is responsible for power management of the computer. It controls backlighting, hard disk spin down, sleep and wake, some charging aspects, trackpad control, and some input/output as it relates to the computer sleeping."
    These are just simple trouble shooting techniques for sleep mode issues.

  • Phone does not ring when in sleep mode

    I have noticed that if I attempt to make a call to my phone when it is 'asleep', i.e. a few minutes after it auto locks, then it does not ring. When I 'activate' it by pressing the home button I see those calls appearing as missed calls. Any idea why this happens?

    This is the exact problem i'm having right now, I don't know why it's happening, but when i have it on the desk and when it's in sleep mode, I can get phonecalls and it won't ring but it won't show up as missed calls either, if i get a voice message i'll get it if i take it out of sleep mode and let it sit with full reception for a minute.
