Display won't go black... (energy saver)

Driving me crazy. I had it set to go dark (the display) after 5 minutes and changed it because I was watching something and now I cannot get the settings to function as they did before/
Any ideas?

Long shot.
Do a backup.
Quit the application.
In Finder hold down the option/alt key while selecting the Go menu item. Select Library. Then go to Preferences/com.apple.systempreferences.plist. Move the .plist to your desktop.
Restart the computer, open the application and test. If it works okay, delete the plist from the desktop.
If the application is the same, return the .plist to where you got it from, overwriting the newer ones.
If you want to make your user library permanently visible, run the below command in Applications/Utilities/Terminal.
chflags nohidden ~/Library/
You will need to do that after any updates.

  • Display won't sleep using energy saver settings.

    I’ve had this problem for some time. I repaired permissions and the sleep timer worked for about a day and then never again. I’ve tried closing all applications that might be running something, didn’t work. Reset pram and tried all the other things I’ve read about and nothing works. My son, who is a system admin and knows OS and Windows said he was having the same problem running Yosemite. I’m running 10.8.5 on a late 2010 iMac.

  • Computer won't sleep on Energy Saver mode

    All of a sudden, the computer will not sleep while on Energy Saver mode. Any ideas on how to locate the culprit?
    Thanks!

    Hi, seb29. One possible culprit is a fax software setting: if the computer is set up to receive faxes, it either won't sleep at all or won't stay asleep for long. In the Print & Fax pane of System Prefs, click the Faxing tab and make sure "Receive faxes on this computer" is not checked.

  • Display dims permanently independent of energy saver

    My three days old MacBook dims since this morning the display permanently down. The first time is became dark the only way to light it up again was a restart or th sleep more with waking up afterwards. Now the display is dimmed permanenty. By changing the brithness to zero and to maximum again I can get it light for some seconds and sometimes for some minutes.
    Does someone know something about this phenomena?
    Thanx, Ricky

    J2Hlive, did you find out what was wrong? I'm having the exact same problem. I was in Safari and all of sudden it went dim, couldn't get it to come back on (brightness is set all the way up) so I restarted. Display was fine after restart, worked for about another 30 minutes and it went dim again and now won't come back up at all, no matter how many restarts, etc.
    I can barely see the desktop but won't the backlight won't come back on.
    Thanks.

  • The Energy Saver in System Preferences has no effect.

    Hi,
    I have my Energy Saver preference set to turn off my monitor after 20 minutes of idle time.  But the display never goes off.
    Energy Saver used to work, now it doesn't and I have no idea why not, or what changed.
    Any ideas?
    Thanks!!

    Perhaps you have some process keeping it awake for some reason.  Have you installed any new stuff recently?
    Try smc and pram reset.
    Open terminal and copy/paste the following line, hit return, post the results:
    pmset -g
    Also post the files in the following places:
    your login items
    ~/Library/LaunchAgents (in your home directory)
    /Library/LaunchAgents
    /Library/LaunchDaemons
    /Library/StartupItems
    And again in terminal the output from the following line (copy/pasteand hit reutrn):
    kextstat -kl | awk ' !/apple/ { print $6 $7 } '
    Maybe some of this info will indicate a possible culprit.

  • Strange behaviour of the Energy Saver settings

    I noticed that the two sliders in the Energy Saver settings seem to work in tandem. If I set the Display to "Never shutdown" (I used this as I don't want my display/TV to go off in the middle of a movie as the mac sees there are no user interactions), and then try to adjust the sleep timer to anything (15min, 30min, etc.), it aligns the slider for the Display at the same point!
    Is it happening only on my mac or is it the way it works for others?

    That would be the simple logic. But, the scenario I mentioned is also a logical one. I have noticed that when I am watching a long Youtube video or an online movie from sites like Jaman, the screen would go off even though the system access is alive. At that time I have to scramble to the mouse/kbd to reactivate the display.
    At the same time, I want to put the mini to sleep after 30min of inactivity. Hence, I want to set the sleep timer to 30min and the display to "never".
    The energy saver settings show two separate sliders and there is no indication that they are attached at the hips.
    Since it works this way for you as well, then I am not doing something weird. I think this is a bug in the OS.

  • How to get external monitor to obey Energy Saver settings

    I have a 23 inch Apple Cinema Display connected to a 2010 15 inch 2.8 GHz i7 MacBook Pro running Mac OS X (10.6.5). I'm running the laptop in clamshell mode. Everything is working fine, but for one thing. For some reason the external display does not obey the Energy Saver Control Panel settings. I have the Energy Saver Control Panel set up so the laptop never sleeps but the display is set to sleep after 5 min. of inactivity. Unfortunately the external monitor never sleeps.
    Anybody know how to get only the external monitor to sleep in clamshell mode?
    Thanks…
    Dragon Dictate in use. Occasionally mistakes are made. I correct the ones I notice…

    Basically, reinstall the Boot Camp video drivers manually and if that doesn't work then go to the AMD/Radeon website and install the Windows drivers directly for your video card model.
    If you want to do a search you will find others that have pretty good luck doing it either way.

  • Screen saver + Energy Saver (Computer Sleep + Display Sleep) won't work since Mavericks

    Howdy,
    Sorry to bother you.
    My computer: iMac (21.5-inch Mid 2011), Mac OS X (10.7.3)
    It took me some time to upgrade to Mavericks, but I did it eventually.
    After having some problems with Spotlight (which was infinite looping indexing... and I just had to turn if off from Terminal), I realized I was encountering another big problem to me since the installation of Mavericks.
    In System Preferences:
    - 'Desktop and Screen Saver > Screen Saver' : it is set to 1 minute;
    - 'Energy Saver > Computer Sleep' : it is set to 10 minutes;
    - 'Energy Saver > Display Sleep' : it is set to 5 minutes;
    - 'Energy Saver > Put hard disks to sleep when possible' : it is checked.
    - 'Energy Saver > Wake for network access' : it was checked. I unchecked it. Nothing changes.
    - 'Energy Saver > Start up automatically after a power failure' : it is unchecked.
    - 'Energy Saver > Allow power button to put computer to sleep' : this option is absent from my System Preferences > Energy Saver, but I would like it.
    So, before Mavericks, everything was working great.
    Now, after 1 minute, or after 5 minutes, or after 10 minutes: it's all the same. Nothing is sleepy. Nothing is energy saving.
    I did not change anything in my computer since I've updated to Mavericks. However, I changed Wi-Fi. Since it was the only new change, I've "played" with 'Energy Saver > Wake for network access'. When I opened my System Preferences, it was checked. I unchecked it. It did not change anything. I'm not sure what it's used for.
    I would appreciate any advice to make it work as it used to.
    Thanks for your time reading and typing your answer,
    Have a good day,
    Regards,

    - 'Energy Saver > Allow power button to put computer to sleep' : this option is absent from my System Preferences > Energy Saver, but I would like it.
    Built into the Software now.
    Do a backup.
    Quit the application.
    Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J.  When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder.  Select Preferences/com.apple.systempreferences.plist. Move the .plist to your desktop.
    Restart, open the application and test. If it works okay, delete the plist from the desktop.
    If the application is the same, return the .plist to where you got it from, overwriting the newer one.
    Thanks to leonie for some information contained in this.
    You might try Spotlight again. That is how the App Store knows what is installed.

  • Mac Sleep Timer (through 'Energy Saver' in System Preferences) won't work

    Hello,
    I have a MacBook (13-inch, Mid 2009) running Mac OS X Snow Leopard 10.6.3,
    and it has been installed with the latest software updates possible.
    (The latest update is the 'Security Update 2010-003')
    Previously I was using Mac OS X Leopard 10.5 on my MacBook,
    and I can vaguely remember the timed computer sleep through Energy Saver would work.
    That is, when the counter's time matches the amount of time I specified (e.g. 10 minutes), the computer enters sleep mode and displays a pulsing power light.
    After upgrading to Snow Leopard I can barely remember the scheduled computer sleep will work as I don't really notice how it sleeps / I will shut down my MacBook before I go to bed.
    ==========
    However, last night I was really tired and slept in front of my MacBook unconsciously.
    When I woke up, I found that my MacBook didn't display a pulsing power light but a continuously-growing power light.
    I tapped the trackpad and the display turned on, so I knew that my MacBook didn't go to sleep a whole night.
    *What that means is that the Sleep Timer (through 'Energy Saver' in System Preferences) won't work.*
    But the timed display sleep DOES work.
    ==========
    After spending a whole day Googling,
    I found that there are plenty of people suffering the same problem as me, although their Macs and OSs vary.
    I also found an official support page from Apple concerning the related issue:
    Mac OS X: Why your Mac might not sleep or stay in sleep mode
    http://support.apple.com/kb/HT1776
    I tried the following methods but still can't resolve the problem:
    _- boot my MacBook in safe mode_
    _- use the 'Disk Utility' to repair Disk Permissions through booting my MacBook from the Mac OS X Snow Leopard Installation DVD_
    _- reset NVRAM (Intel-based) (as PRAM is used by PowerPC-based Macs)_
    _- reset SMC (System Management Controller)_
    NONE of the above-mentioned methods can resolve the problem.
    Althought I am sure that the Spotlight isn't indexing the hard drive, and I just start my computer and do nothing and wait for the scheduled computer sleep, the scheduled computer sleep just won't work.
    In the other Mac forum, I saw someone suggest installing an application called PleaseSleep:
    http://www.dragonone.com/products/macosx/pleasesleep/
    It works.
    But I really want to find out what caused this problem as this is a function shipped with Mac which is expected to work normally.
    What's more, Apple is claiming to be a green Apple, right?

    ==========
    Looking forward to your replies! Thanks in advance!

    Found this discussion by googling "com.apple.systempreferencescouldn't find any matches"...
    One month ago I bought a brand new Macbook Pro 13", and after a couple of weeks I realized it wasn't sleeping on its own when it should, per the system preferences. (I did sleep when I chose "Sleep" in the menus or closed it... It just wouldn't sleep on its own, while open.) What was extra frustrating was that it was intermittent... It would sleep on its own maybe 1/3 of the time, but other times it would NEVER go to sleep. I deleted PowerManagement.plist, reset the SMC, etc... No luck.
    I took it to the "geniuses" at the Apple Store, and the guy took all of five minutes trying to diagnose the problem. When my MBP wouldn't sleep on its own, he promptly replaced it with a new one. That was nice, but I actually would have preferred that he diagnosed and fixed it. (I think the store was so swamped with people coming in for service that day that they were doing anything they could to close cases and get customers out of there ASAP.)
    Now, sitting here with my 48-hour-old MBP, I still have the problem. The other one was so new that I had barely put anything on it yet. The only applications I had put on it were MS Office for Mac 2011, Firefox, Chrome, and Adobe Flash Player. I've put Office and Flash Player on this one, but not yet Firefox or Chrome. That's it. No other customization or fancy business.
    I looked into the Console just now, and I see the "Couldn'tfind any matches" entry popping up again and again. The last three seemed to pop upright around the time when my MBP should have gone to sleep on its own, but not down to the second, so it's hard to definitively point at that and say it's it for sure.
    They need to fix this!!

  • Button to toggle between display energy saver modes?

    Normally I keep my System Preferences: Energy Saver option set to put my G4 iBook display to sleep after one minute, to save the screen's life expectancy.
    However, I have some applications that don't work with that setting-- so when I use those apps, I have got to the Apple: System Preferences: Energy Saver option and drag the bar over to where the display is Never put to sleep.
    Then when I'm done with the app, I have to do it all over again to reset putting the display to sleep after 1 minute.
    Is there some kind of macro or script to get where I can press a button and toggle betwee these 2 power save modes?
    Thanks

    Hi Christopher!
    Axl's suggestion is an excellent one!
    The procedure is explained, with a bit more detail, HERE.
    Quote:
    "Not really a shortcut, but this method, will enable you to quickly access the Energy Saver pref pane.
    Open System Preferences.
    From the Toolbar's System Preferences contextual menu, select Hide System Preferences.
    System Preferences is still loaded, as you can see the black triangle under the Dock Icon.
    If you position the cursor on that, and hold down on the mouse, a hierarchal menu will appear.
    From that you can navigate to any Preference Pane in SP.
    When you have finished with the Pane, select Hide System Preferences once again.
    You just have to remember to Hide rather than close SP."
    Good Luck!

    Anyone else having this issue? Worked great in snow leopard. Updated to 10.7.1
    //Niklas

    Ok so I happened to figure it out while on the phone to apple support. Even though the guy was very nice, I think I knew more than him! He was explaining very basic resolution principles I played about. I had the second option in displays resolution. All I did was unplug the HDMI cable, click on 'best for display' then plugged the HDMI in and my resolution on the normal monitor changed to the normal blue, then went black momentarily and then changed to a strange resolution but another window appeared that said SONY BRAVIA HDMI at the top! Hey presto! Don't know why it didn't do it yesterday - I probably left the HDMI cable in or something! Oh well. Problem solved!

  • EMacs Energy Saver function won't work.

    Did anyone notice the same strange thing with the Energy Saver Control Panel after the 10.4.10 update? It won't work anymore... I would like to get this thing to sleep, to save electricity... Yes, I did check the Energy Saver Control Panel/Screen saver settings and this thing suppose to go to sleep after 3 hrs but it won't. Any suggestions? Thanks!

    harrytroeger,
    Welcome to the Apple Discussions!
    What peripherals do you have attached to the eMac? In particular, do you have a all-in-one printer/copier/scanner or stand-alone scanner attached? It's possible that the scanner driver in that case conflicts with the latest OS X version.
    Is "wake for Ethernet network administrative access" checked in the Energy Saver options tab?
    More generally, try resetting PRAM by restarting, then as soon as the display goes dark, press and hold down command-option-p-r keys until you hear three sets of chimes, then release the keys. You may need to go through System preferences and reset anything affected by resetting PRAM (see What's stored in PRAM?).

  • Energy Saver Display Sleep Not Working

    I have a late 2011 MBP with an external 27" Apple display. Was working great under 10.7.
    After upgrading to Mountain Lion the monitor will not go into sleep mode regardless of the Energy Saver settings. I can keystroke the monitors to sleep but they won't enter sleep automatically.
    I've tried PRAM and SMC reset.
    Any ideas? Bug for Apple? Anyone else having this problem? I've found at least one other guy online with a iMac that's having this problem.

    So this seems to be working now. No software updates or other changes. The only thing I did different was to lock the energy saver settings. After that it started working.

  • Does turning off energy saver include never letting the display to sleep? A warning alerts me that its life might shorten... Thanks!

    Does turning off energy saver include never letting the display to sleep? A warning alerts me that its life might shorten... Thanks!
    (I'm doing this for the recalibrating of the battery etc...)

    It would shorten it's life if you leave it on year 'round. For the amount of time to calibrate the battery won't hurt it.
