  • Screen dimming before sleep

    No matter how many times I check and uncheck the option to "reduce brightness before sleep" I find that a few days later the screen starts dimming again. When I go to see if the option is unchecked like it should be, it always is!! Anyone else having this problem?

    Note that the half-dimming is there for a purpose. The florescent tubelets that illuminate your LCD are very expensive. the half-dimming is there to extend their life, and yet provide near-instant illumination if the computer detects activity by the user.
    Admittedly, it would be nice if this was configurable by the user, but that is the reason the half-dimming is there.

  • Display dims before sleep, no matter the setting

    My MacBook will dim its screen (ie: reduce brightness) after about 10 seconds of idle time. I've read to stop this you need to uncheck the "dim display before sleep" checkbox under energy saver preferences. I've done this for both the power adapter and batery settings, but the display still dims! It will dim when running from the batery or the power adapter. It makes watching DVD's useless.
    Has anyone else seen this? I find it annoying, but it's driving my wife crazy.

    One option to try would be to change the login settings so that you are not automatically logged in when you start up to the computer. After you make this change, log out, log back in, toggle that display sleep setting on then back off and check the result.
    Something else that might be worth a try...
    First, I'm not sure what preferences, if any, will need to be reset after this. Also, I have not done this and do not know the result. As always, backup your stuff.
    1. Go to the folder ./Library/Preferences/SystemConfiguration (not your Library folder but the one at the root level of your hard disk).
    2. Drag the file named com.apple.PowerManagement.plist to the trash. You will be prompted to enter your admin password when you do this.
    3. Restart.

  • How do you change the settings you have the screen dim before it shuts off

    I know on older OS the screen would dim before the computer shuts off. I was wondering how to do that on Maverick. It doesn't seem to come up on display settings or energy saver.
    Is it not on Maverick or have I not found it yet?
    Thank you

    This is all I have, I do not seem to see an option for what you are saying

  • Pavilion Touchsmart 23 screen dim after sleep since Windows 10

    I have tried this, and it has not changed the problem. FYI, adaptive brightness was off by default on my computer after I upgraded to Window 10. Please escalate our issue, it is driving me crazy!

    I also have a HP Touchsmart 23 with Radeon HD 8570D display adaptor exhibiting the same issue.  Microsoft and HP report no available updates and the adaptive brightness is OFF. There are no brightness controls on any control panel page including the power managment sections. The Windows 10 notifications pull-up for settings does not have a brightness slider.   Rebooting is the only method I have found to restore display brightness to a usable level.  Previously on  this thread it was stated ....According to the available list of supported drivers for your desktop computer, there is currently no Windows 10 graphics or chipset software published at the moment.  The orginal post is from August 4, so now more than one week later a solution has not been forthcoming.    Please escalate this issue as HP was reminding me to join in the Windows 10 upgrade and now that I did,  I have an ongoing problem with the hp pavilion 23.   Seems HP missed the boat and was recommending the upgrade knowing the chipset in the computer was incompatable.   Shame.         

  • The screen dim on 24 inchs imac

    The screen dim before sleep on an Intel-based Mac's built-in display, even if the Energy Saver setting "Automatically reduce the brightness of the display before display sleep" is disabled. This setting may no longer be in effect after restarting the computer.
    any body has a fix for this.
    see the bug description at.
    http://docs.info.apple.com/article.html?artnum=304092

    Yes, I do, I am hoping for a permanent fix from Apple, but in the mean time I have a script which will run each time you reboot to disable the screen dim.
    I have posted this as a separate thread.

  • Screen dimming/sleep

    Under 10.4 and before, the screen sleep and "dim before screensaver starts" settings were honoured even when the mouse pointer was in a "disable screensaver" corner. That gave me a very simple (and resource-cheap) screensaver that didn't lock the screen - great for when I'm doing something else in front of the computer.
    10.6 no longer does this: put the mouse pointer in such a hotcorner, and the screen remains on, regardless of the display sleep setting.
    Is there a workaround? As far as I'm concerned that could be something like a hotcorner that disables the screensaver password protection temporarily, but the ideal would be a behaviour like in 10.4. After all, any kind of energy saving is better than none, not so?!

    Note that the half-dimming is there for a purpose. The florescent tubelets that illuminate your LCD are very expensive. the half-dimming is there to extend their life, and yet provide near-instant illumination if the computer detects activity by the user.
    Admittedly, it would be nice if this was configurable by the user, but that is the reason the half-dimming is there.

  • Macbook pro screen dims after waking from sleep?

    Does anyone know why my macbook pro screen dims when waking from sleep or waking from my screen saver? I can't get it to stop doing this. Thanks.

    It sounds like I have the same thing happening. It's more like the colors are washed out, like there is less contrast. I have a hot corner set up for my screen saver. Once I activate the screen saver for a second and then deactivate it, the Macbook screen goes back to normal. I have a 30" Samsung 305T monitor set up as a second (main) screen for when I'm working at home, which is most of the time. I haven't had it unplugged from the Macbook since this started, so I don't know if it happens by itself. I do know that the Samsung looks fine when waking up from the screen saver at the same time.
    I tried to find others with this problem in this forum, but got tired of looking through all the other posts that had nothing to do with this problem.
    Can anyone help us?

  • Screen dimming

    hey, i'm going to hook my macbook to my HDTV via the DVI adapter and then HDMI to the TV. My question is this: My Macbook has a screen dimming function, whether it's plugged into a wall socket or not after a short time of no operation the screen goes dim. Will the screen of my television go dim?
    If so, how can I avoid this issue? I'm using Tiger and there seems no way to adjust this setting.

    thanks for replying Simon. I have answered my question in a way. I don't know if the television set will dim but I've found out how to stop the dimming on the computer display in Tiger and on Leopard. You are right it's in Energy Saver settings. Uncheck the "Automatically reduce the brightness of the display before display sleep" this is in the options menu in Energy Saver. Then put the sliders on 'Never.'
    Thanks

  • Screen Dimming Setting Problems. . .

    Wondering if anyone else is experiencing this: In system preferences energy saver/options I have checked "automatically reduce brightness of display before sleep." The problem is that if I don't check that - -which I would prefer not - - my screen goes dark after about 60-90 seconds of inactivity. My ideal is to not have the screen dim and then go to screensaver but apparently there is no way to do this.
    My question:Do others have this problem? If you solved it, how? All suggestions appreciated.
    Thanks!

    I talked to a product specialist from Apple (through Applecare after waiting for an hour!) and he acknowledged it is not supposed to behave the way you and I are describing. He sent m a little program that does a "data dump" which I then emailed back to him which he sent on to the engineers, and they are supposed to get back to me the next couple of days. We'll see.
    Obviously, you're in the same boat. I find it totally obnoxious to have to touch the trackpad every minute or so to keep the screen bright. Major glitch.
    I'll post again if Apple solves this one. . .

  • Mac Pro screen dimming

    My screen is dimming after 5 minutes.  I've read through the forums and found a few answers, but I have my display set to never sleep, and I do not have the option of "automatically reduce brightness before display goes to sleep" like my iMac and Macbook Pro do.  Please help, it's really annoying watching a movie and 5 min the screen dims.
    Thanks,

    Hi,
    I had the same issues when I bought my macbook pro a few weeks ago.
    Its a feature built in that dim and brightens the screen with an ambient light sensor.
    The sensor is underneath the speakers so when your hand goes over and effects the lighting your screen will dim/lighten.
    To turn this off go to System Preferences > Displays
    then at the bottom it will say Automatically adjust brightness as ambient light changes, uncheck that.

  • IMac screen dims itself automatically; all attempted fixes fail; how can normal brightness be restored?

    Machine and OS:
    2007 white plastic iMac with 20" screen and 2 GHz Intel Core Duo, running OSX 10.6.8.
    The problem:
    The screen dims itself for no known reason. It is especially noticeable when waking from sleep: for the first second or two after waking up, the screen is at normal brightness -- but then after a second the computer seems to "remember" some setting or command, and the screen unquestionably dims itself to be about 20% or 25% darker.
    Because the screen for a brief moment after waking is at full brightness, that proves to me that there is nothing physically "broken" about the display that prevents it from illuminating fully; it could be at full brightness if it "wanted to," but some kind of software or firmware glitch is telling it to be dimmer.
    The fixes I have attempted so far -- ALL of which have FAILED (so please don't recommend them again):
    - Reset the NVRAM or PRAM by holding down Command-option-P-R upon startup. For some reason this technique doesn't cause the second chime, so it doesn't appear to be zapping the NVRAM or PRAM or whatever, and consequently has no effect on the dimness, which persists unchanged after restarting.
    - Reset the NVRAM using the terminal command ' sudo nvram boot-args=”-p -r” ', as recommended on this page: https://discussions.apple.com/thread/2172681?start=0&tstart=0. I can't tell if this really did reset the NVRAM (it doesn't cause a second chime upon restart), so I'll just have to assume that it "worked" -- but except for one instance, it had no effect on the screen dimness. (That one instance went like this: after issuing the Terminal command and restarting, the screen did go back to full brightness -- but only until the first sleep. After waking from that sleep, the screen once again dimmed itself as before. And no, I have not been able to repeat this momentary "success"; on all subsequent attempts following the exact same steps, no brightness has ever returned at all since.)
    - Reset the System Management Controller (SMC) as recommended on this page: http://support.apple.com/kb/HT3964 . Basically this just entailed shutting down the computer waiting a few seconds, then unplugging it, waiting a few more seconds, then plugging it back in, then waiting a few more seconds, and then finally starting it up again. Result? No change: screen still dims itself.
    - Pressed the "brighter" and "dimmer" keys on the keyboard; those do make the brightness go up and down, but the top brightness setting is much dimmer than it should be (and used to be). All the way to brightest setting = still noticeably dimmer than normal.
    - Used  the "brightness" slider in the System Preferences > Displays > Display window. That also does indeed adjust the brightness up and down, but as with the keyboard brightness keys, the highest setting is still too dim.
    - Readjusted the "Calibration" in the System Preferences > Displays, which had no noticeable effect; even when going into Expert mode and adjusting every little aspect of the screen display's default settings. Those all seem to be about color balance anyway, not about brightness. I now have three different new calibration settings, and clicking back and forth between them and the default setting makes no real significant difference. Whatever setting I choose, it is still dimmer than it should be, even though in all my attempts at calibration I tried to make it brighter.
    - Tried going to System Preferences > Universal Access > Seeing and adjusting the "Enhance Contrast" slider and trying out "Black on White" vs. "use Greyscale"; none of that helped, and did not seem to be relevant to the problem.
    - Tried going to System Preferences > Energy Saver, and clicking the "Automatically reduce the brightness of the display before display sleep" check box on (and then closing the preference pane) and then off again (following the advice at http://support.apple.com/kb/TS2309?viewlocale=en_US) -- but it had absolutely no effect whatsoever on the brightness level.
    Final note: The keyboard and mouse are both Apple products and work perfectly, and the machine has no other performance issues. Just the dimming, which started a few weeks ago inexplicably and without warning.
    I can't imagine what is causing this problem, and I've absolutely run out of ideas about how to fix it. One thought I had was that maybe the screen is dimming itself due to detected ambient illumination, but I'm not sure 2007 iMacs even have that feature, and also the screen remains dim whether the room is dark or bright. Maybe there is an ambient light detector somewhere that is malfunctioning?
    Help! How can I solve this? The screen is not so dim as to be unusable, but it's annoying enough that I'll have to get a replacement machine if this is not fixed eventually.

    Does an external display also act in a similar manner as the internal one?
    Some earlier Intel-based iMacs had graphic processor card issues; not sure what
    the symptoms of the majority of them were, but some had odd patterns, others
    went black, and some would range from OK to totally unusable. Among others.
    So there is a chance the graphic processor may be going out; or just the circuitry
    that controls the backlight. An inverter may be weak or other circuit to the display
    could be wearing out.
    http://www.apple.com/retail/geniusbar/
    If you have access to an Apple Store with Genius bar, they can perform some kinds
    of diagnostic tests there even though the computer is out-of-warranty; that may be
    of help to narrow down the cause of the symptoms you've noticed. They may not be
    able to repair it, however, at an Apple Store; as it is rather old by today's standard.
    An Apple Authorized Service Provider could do repairs and testing on older models
    the Apple Store's Genius and other may not be set up to handle due to vintage.
    Find an Apple Authorized Service Provider
    Visit an Apple Retail Store
    There is a country locator page to help find either of the above in regions outside
    of the US & Canada, not sure how the above links would work; and it appears my
    bookmarks to the country locator page may not be accessible now to post here.
    You may be able to get an idea about what kinds of parts support the display
    function by name by looking into an iFixit.com repair guide for your iMac series.
    Hopefully the parts supporting the display are the reason it is dimming down, as
    a graphic processor failure likely would exhibit other behaviors than just dimming.
    PS: I see you've added content to your thread after I'd started working on this
    & the answer likely is a hardware repair; professional testing is worth the time
    and you seem to have at least one other thread on the same topic....
    Good luck & happy computing!

  • Air Screen Dims when watching movies

    Hi all! This is a stupid question. I've just purchased a new macbook air 11.6 in and when watching movies (not in ful screen) the screen dims, Im assuming because of inactivity with keyboard, etc. I dont like to watch all movies in full screen, so how do I change the settings to allow for longer 'inactive' times? Meaning, I don't want the screen to dim after only 5 minutes. Thanks!

    In System Preferences > Energy Saver > uncheck "Automatically reduce brightness before display goes to sleep"
    Also adjust the sleep timer to suit.

  • Screening Dimming Problem

    Hi everyone,
    I find the "automatic dim display before sleep" to be very annoying. So naturally, I go into Energy Saver, and disable it. Ok, all is well, until I connect an external monitor/TV. Then even with or without the monitor connected AND the dimming check-box still deselected, my PowerBook's display defaults back to it's Auto-Dim setting. Argh, how can I fix this? Has anyone run into this problem?
    I've tried the Terminal "pmset" option of changing the halfdim setting to 0 instead of 1, which is the same has using the Energy Saver option. Even after plugging and unplugging the ext. monitor, the screen dimmed after a while, and I verified in Terminal (pmset -g), that the value of halfdim was indeed still 0.
    Thanks,

    Hi William, have you tried creating a test user and testing the behavior in the fresh account? If it behaves in the new user then delete ~/Library/Preferences/com.apple.systempreferences.plist then log out and back in or restart.

  • Auto Screen Dimming

    Hi everyone,
    I finally have a problem with my MBP! I say this in an excited way, because quite a few are hoping that my MBP will explode or something... Anyway, I have my video set (energy settings actually) to NOT dim my screen before sleep. It is doing it anyway. I also don't recall my screen saver kicking in on my PB if I had iTunes playing. It does now. Some of these are real lame issues, but I'd still like a fix.
    Bob

    I have my video set (energy settings actually) to NOT dim my screen before >sleep. It is doing it anyway.
    Although your energy settings may keep the screen on, you may have it adjusting to ambient light. Go to system preferences>displays and check off "automatically adjust brightness as ambient light changes"
    screen saver kicking in on my PB if I had iTunes playing
    Go to system preferences>desktop & screen saver select screen saver at the bottom it says start screen saver and you have a slider. It is probably not set to never.
    My recollection is if you are not using your keyboard, mouse, trackpad, etc. for that amount of time, the screen saver comes up, even if a program is running like iTunes.
    It also sound similar to this issue Mac OS X: Screen Saver Slide Show Goes Blank (or Black) http://docs.info.apple.com/article.html?artnum=106880
