Display dimming

For some reason my display still dims before putting the display to sleep on Power Adapter. I've unchecked the box and it still dims... any help?

I have this issue as well. I also had a powerbook but this did not occur after unchecking the auto dimming setting. On my mbp if I lock the settings after unchecking the setting the display doesn't dim. However when I restart the computer the setting is unlocked again and the display will dim after a few minutes even though the auto dimming setting is still unchecked. So I check it again, close system preferences, then go back uncheck the setting and also lock it again. That seems to work, at least until you reboot it. After sleep it will still work properly.

  • Display dims with no reasonlem occuring, then for no reason I can thihnk of

    I have a 21" G5 imac. the problem is my display dims for no reason. This is an intermitant problem. I can go for long periods with out the problem then for no reason it will do it again.
    It now dims after about 3 minutes starting up the computer. It does not go blank, just dims somewhat, but because I use the computer to edit photos in Photoshop it makes it unusable for photo work.
    I got the computer in the Summer of 2005 and it was doing it while under warranty but since it was very infrequent I did not report the problem to Apple care. Of course it is now out of warranty.
    Any ideas of what is causing the problem, and what to do?
    Thanks in advance.

    I have a similar problem. The screen will intermittently just go dim. I also decided not to give the machine up for warranty service because it comes and goes. The screen setting always says it is at full brightness. I installed a temperature monitor program, and it seems to be heat related. If I leave the computer sit for a while and the screen to turn off, when I come back it is back to normal. I found that if I put the iMac to sleep, it would re-brighten immediately on waking up. But now the machine usually turns off if I put it to sleep, so I have quit doing that....

  • X230T display dims after BIOS start

    MY X230T was originally supplied with Windows 7 Pro. Apparently as a result of twiddling with the power management options on that platform, the display dims significantly between starting the BIOS and logging in to Windows. Specifically: 1. The BIOS screens are displayed at normal brightness 2. The screen then dims to a very low level while Windows loads. The hotkeys are not active at this time. 3. Under Windows 7, the login screen would remain dim until I pressed a key, or clicked on the screen with the mouse. Under Windows 8, the "lock screen" is already displayed at full brightness. This would not be a big deal, except that when booting another OS from a CD (e.g. Clonezilla Live), the display can remain dim, which makes the SW very difficult to use. Needless to say, the hotkeys also do not work under such foreign OSs. I have moved on to Windows 8 as a result of problems with VSS and can no longer find any such power options, either in the BIOS settings, the Windows Power Options or the Power Management settings in the Lenovo Settings metro app. How can I get the display brightness to remain constant during startup?
    X320T running Windows 8 Pro x64

    Hey, I have same or similar problems with graphic card on same notebook (P200D 12O PSPBQE):
    Some times, hard to define, probably when computer is connected to the electricity and used for some hours, a strange effect occurs: the background, strangely without the active window looks like it has reduced number of colors to like 16. Maybe 'without active window' means that only certain ranges of colors are affected and mainly white active window is not because of it's white color, just a theory for now.
    The problem is solved either by restarting or by unplugging the power cable. Unplugging the power cable from the computer causes serious not-very-healthy-looking flickering of the screen which after few seconds becomes black and then recovers back to normal. After such recovery, the Vista says something like: the dispaly driver or hardware recovered from serious error. And then the colors are ok again.
    I suspect that in my case the problem is caused by electricity disturbance, probably caused by the older refrigerator, because every time I notice this problem, the refrigerator is on. Or precisely true: I have never seen the problem when refrigerator was not working, at least ofr now. I plugged the computer on other end of appartment, electricaly farther away from refrigerator and on another fuse, but the problem still occurs, but less frequently, I think. I will try to take picture of the problem.
    Quite strange problem, probably hard to present to the people who sold me the computer. Maybe the pictures of the problem will help.

  • New macbook pro display dims in and out

    I just got my new macbook pro a few weeks ago. The display dims in and out at times, why does this happen? What can I do to fix it? I really don't wanna replace it already or what not.

    Welcome to the Forums!
    Most likely the ambient light sensor - the system is set to automatically adjust brightness based on changing light conditions. You can test this out - put your hands over both speakers and your display should dim quite a bit. To turn this feature off, go to System Preferences > Displays > Display tab and UNcheck the box for Automatically adjust brightness.

  • Display Dims before boot and after shutdown are complete

    This is probably a stupid question but a while back I clicked on an option to have my display dim during the shutdown process and stay dim until it was completely booted.
    I would like to turn this off but I can't find where the option was.  I've checked the device manager, BIOS, standard and advanced display settings the Windows and lenovo power settings with no luck.
    I have a thinkpad W500 running Windows 7 Pro 4gb of ram with a recent upgrade in hard drive to a 750 gb WD black series drive.  I am also running IE9 which I see has some compatibility issues so I hope I can post this.

  • T530 Win 8 64 w Intel HD Graphics 4000 display 'dims'

    I have a problem that is similar to others listed in the forums but the listed solutions either don't apply or don't work for me.
    Configuration:
    T530 2394CTO
    Windows 8 64 bit
    Bios G4ET96ww (2.56)
    Issue:
    When the screen is largely dark, the display 'dims'. I have a dark desktop image so, for instance, if I minimize active windows, the display dims. The brightness setting is not changing so on the brightness setting it still shows full brightness. When I then switch to a mostly white window it then takes maybe 4 or 5 seconds for the white to change from off-white to bright white. As long as there is significant portion of the built-in screen that is light colored it stays that way. As soon as the majority of the screen is 'dark' it dims again.
    It is not the Intel HD Graphics Drivers as suggested here.
    If I check the drivers with Lenovo System Update they show as up to date. There is a more recent version on the Intel site but if I try to install it it says my computer does not meet the requirements.
    It is not the adaptive brightness settings as suggested here and here.
    On my version this setting does not show up in the Intel Graphics and Media control panel but there is a setting in the advanced power plan settings and I have disabled the adaptive brightness there.
    Any other suggestions?
    Thanks in advance!

    Hi Dali99GRT,
    I see you have several questions today. I will do my best to help you with them.
    The difference between an Integrated and a Dedicated Graphics card are as follows: (information from Top Ten Reviews)
    Integrated
    An integrated graphics processing unit (GPU) doesn't use its own RAM; it utilizes the system's memory instead. So, if you have a computer with 4GB of RAM, the video card can use anywhere between one and five percent of the available memory for graphics processing. Of course, this percentage varies depending on the size of the task, especially if you're multitasking or playing a game.
    Dedicated
    A dedicated, or discrete, GPU has its own independent source of video memory, leaving the RAM your system uses untouched. If you have a GeForce GTX 680M video card with 2GB of video memory, for example, that memory is completely separate from your computer's 8GB of system memory. Dedicated cards are perfect if you are into serious gaming or are a professional graphic designer.
    As for the Approx. Total Memory this is the video memory of your graphics card. Your Intel Graphics card, is an integrated graphics card, that is most likely shared memory. This means some of the video memory is taken from your RAM or system memory. That being said, Windows 8.1 may not use as much of the video Graphics to run as Windows 7 does.
    And the detailed information for the External VGA card, I am at a loss. Your best bet is to check out some websites like Amazon or CNET for this. I did find this information on How good are USB video cards? that may help you with your decision making.
    I hope this information helps, please let me know.
    Thank you and I hope you have a great day!
    I worked on behalf of HP.

  • Changing display dim

    Hi guys.
    I have arch running on my laptop with gnome3.
    The display is dimmed after few seconds that I'm not active. Very often, I'm reading text or staring my code on my machine and this is annoying. Power management doesn't have any option to cancel this.
    How can I manipulate this?

    Check out Settings -> Screen and uncheck dimming.
    Although it didnt work for me :
    I personnally chose tu use laptop-mode-tools (see wiki) on my T420 to control the brightness. It works nicely BUT and here is the thing: Gnome keeps dimming my brightness anyway even if I unchecked this. In dconf-editor under org.gnome.powermanager there is no option.
    I do remember Gnome 3.0 having options in dconf-editor to deactivate display dimming and leave it to hardware.
    Sorry for not being able to help. I actually wanted to post a thread about this but I saw yours and it seemed related.

  • MBP display dims slightly off while reading article....???

    Hi all,
    I have done a lot of research in this discussion, but couldn't find the resolution. The MBP display always dims slightly off while not in use for 1 minute. If I check off the setting in the Energy Saver/Option/"Automatically reduce the brightness.....", then display dims off completely (dark...)!! It's very annoying since ever time when I read an article without moving mouse for 1 minute, then the display dims off slightly. I have to keep moving the mouse so it doesn't dim off.
    Does anyone have the same issue? Does anyone find any resolution?? I talked to the Genius guy and they said they don't know what to do about it....
    Thanks in advance.

    Okay okay, I see what you're saying... I thought you were saying it goes off and doesn't come back on or something.
    Anyways, this is normal behavior but it can be prevented. Go to energy saver preference panel. For both battery and adaptor, slide the "put displays to sleep after" slider all the way to the right, which is never. Make sure also under the options tab, that you uncheck the "reduce brightness..." box.

  • MBP display dims slightly off while reading a long article....???

    Actually my roommate has a MBP too... he has the same problem.... only takes 1 minute for the display to dim off (not completely, only dim off the brightness...) but he said it doesn't bother him. For me it is really annoying...
    Does anyone have the same issue? Does anyone find any resolution?? I talked to the Genius guy and they said they don't know what to do about it....
    Thanks in advance.

    thats just what it does for me, i dont have it set to anything to control that,
    edit- found the app you can get to fix it (you cna test drive it or pay 9 bucks for teh full app http://www.apple.com/downloads/macosx/apple/macosx_updates/macosx1051update.html

  • Display dimming buttons don't function on wireless keyboard.

    Display dimming buttons do not function on the wireless keyboard, but do function on the MacBook Pro's keyboard. That is, I cannot control brightness of the MacBook Pro's display from the wireless keyboard, but can do so with the MacBook Pro's built in keyboard. Neither of the keyboards seem to have any control over the external monitor. The wireless keyboard is a brand new Apple aluminum keyboard. How can I gain control of the wireless keyboard's brightness control buttons?

    Hello roytel:
             Welcome to HP's forum. Sorry your keyboard has become corrupted. Unfortunately there is no way to excess the keyboard. They are manufacturered preinstalled software as a set. That is Bllue Tooth Device, Mouse and Keyboard. The only solution is to replace the set. I am on my third Keyboard, Mouse and Blue Tooth Device set. Please check and compare the prices at HP's store and HP's part store. HP's parts store was cheeper when I bought my last set. I have on hand a cheep USB Keyboard as spare. This way you can continue using your computer in the mean time while your new keyboard set is being ship. Here is HP's Part Store link http://h20141.www2.hp.com/hpparts/ and here is HP's Store Wireless Keyboard sets link http://www.shopping.hp.com/en_US/home-office/-/search-SimpleOfferSearch;pgid=9ENQqrMsvdhSRpHAjtpLkm....+  You are welcome use your Sound Icon by the clock on Task Bar as the volume control or any of  your media  players untill your new keyboard arrives. frrw

  • Forced Win 8.1 Upgrade - Display Dimmed (10%) on Lenovo Z500 Laptop

    As you know - Microsoft forced the 8.1 upgrade on 8.0 users. The Lenovo Z500 laptop has a display problem (dim lit monitor) once 8.1 installed. There appears to be no firmware / software fix - so what is the solution ? In the event there is a hardware swap
    or another alternative, please let your customers know. Do not compromise your Goodwill, maybe your legal staff should have a talk with Microsoft. Microsoft compromised Lenovo Customers by forcing the 8.1 Upgrade. As others, one day it downloaded and installed
    on its own without user intervention. Now I have a laptop that is so dim, it is no longer functional for me. Trade-In Options ? 
    Or Microsoft Operating System Fix ?

    Look at britishdez link, it says:
    5
    After upgrading, you may install the latest Windows update. However, you cannot adjust the brightness on U310, U410, U510, U410 Touch, U310 Touch, Z500 Touch, Z500, Z400, Z400 Touch, Z380, Z480, Z580, Z485, Z585, S300, S400, S400u, S400 Touch, S405, S206, G485,
    G585, and N480 after Windows update.
    Uninstall the VGA driver and reinstall the original driver.
    Upgrading your Intel Graphic Driver should help. Good luck!

  • 20" Apple Cinema Display - Dim Backlight Fixed! (Sorta)

    Well... as many other Apple Cinema Display owners have experienced the infamous dim backlight with the "short short long blink" - I have some wierd news to report...
    Mine got fixed last night on total accident.
    Last night there was a huge storm in my area and there was a lot of lighting and massive down pour of rain, stay with me honest I have a point.
    My G5 was on last night while I was asleep in the other room within visual range of the display. There was a lighting strike on my property about 20' from where my office is which is on the corner of the house. The lighting hit the tree and send an obvious surge of power into my house and zapped some electronics.
    Wireless router, cable modem, and thermal label printer all bit the dust - and the USB ports on the back of the ADC display. I jumped up from the sleep and saw the monitor light up out of screen saver because the house shook so hard. I ran over to the machine and tried to move the mouse and keyboard and no go since the USB ports are burned out, but the monitor was FULLY LIT UP. I have unplugged the monitor and plugged it back in multiple times, turned the machine off and let it sit and it still is working great minus the USB ports.
    My hunch is this... because of the dead USB ports which are no longer drawing any power, is it possible that the USB ports are the cause of the "short short long blink"?
    My screen went dead initially when it was in a deep sleep mode and NEVER came out of it until now.
    So basically what I am suggesting is that someone try and unhook the USB (if it is even possible) and see if that helps with their display - if not, I guess I am just lucky and my Apple Cinema Display is just lucky to not have fully bit the dust.

    We can't answer that because that's going to depend on who you talk to. By the book, AppleCare covers defects and not accidental damage, so you could get a No answer if they determine it was not due to a defect. But realistically, sometimes you talk to someone who decides to use their ability to authorize an exception and get it fixed anyway. The only way to find out is to call AppleCare.

  • Early-2009 Macbook display dimming

    I have read several posts and watched several videos on this already, however my problem seems slightly unique as to what I have read so far. (I may be wrong about that.) My Macbook's display constantly dims to an almost black, I didn't realize the display was even on until about 2 hours ago. But I can see that the display is indeed on, I can turn it all the way down with the F1 key, then up with the F2 key, but it's hit or miss. Sometimes the display will brighten, most other times it will flicker on and go back dim. I have posted a video on this, because it was kind of hard to explain, figured it'd be easier to troubleshoot if you knew what it was doing. https://www.youtube.com/watch?v=OYb4Y2XE4Pw&list=UUCNnIhMJdjY9Kf_jgC2vjPw
    Comp Info: Early-2009 Macbook, Running Mavericks 10.9.4
    What I've tried: PRAM reset, ran Disk Utility repair, booting into Safe Mode, SMC reset, Changed energy saver modes to never dim screen... I'm out of ideas, does anyone have any suggestions.

    That's ALL they did at the Apple Store? Really? Normally they'll run a diagnostic on it and at least tell you what the problem is.
    Is the macbook starting up? Do you hear the start up chime? If so I'm guessing that the graphics chip has failed. IF that's the case you'll more than likely need a new logic board. Keep in mind that I'm guessing, it's impossible to diagnose hardware prolems on a user to user message board.
    You can always try resetting the SMC and PRAM but I wouldn't hold my breath.

  • Display Dims

    I have a fairly new MacBook and I am having a problem with the display always dimming. At first I didn't give it much thought because I watch alot of video and thought that since I wasn't doing anything, it just dimmed for the lack of use (other than watching video). Now however, I have been doing alot of Photoshop work (color correcting/retouching, etc) and it dims all the time. Its hard to color correct when a display is always dimming. So my question is, is there anything I can do prior to contacting Apple?
    Thanks for any input!

    Some feedback for anyone that has this same problem.
    OK, the problem I had with the screen and dimming was resolved by Apple. I took it to Apple service this weekend and they took care of the problem within a couple of minutes and now no more problems. All they did was reset the System Management and sapped the PRAM. See the attached link for resetting the System Management Controller.....http://support.apple.com/kb/HT1411
    They did this and then sapped the PRAM and no more problem. Hope this helps. Nice to have a screen that doesn't dim anymore!

  • Display dimming, then brightening quickly

    Title says it all. Machine is a mid-2009 15" MBP, OS X 10.6.7. Energy Saver settings are:
    Battery:
    Computer sleep: 10 minutes
    Display sleep: 2 minutes
    SSD sleeps when possible, and the display is set to dim on this power source and to reduce its brightness prior to sleeping.
    Power Adapter:
    Computer and display sleep: 10 minutes
    SSD sleeps when possible, machine wakes on network access, and the display reduces brightness prior to sleeping.
    This happens only after inactivity, when you'd expect the display to dim as those settings specify -- but despite me not having a hand on the laptop, the display brightens immediately within a fraction of a second as if I'd brushed the trackpad.
    This has been an issue across clean installs of OS X, before/after permissions fixes, and resetting of Energy Saver settings in Preferences, so I'm at a loss.
    Any thoughts appreciated.

    I've read you never want to put a SSD drive to sleep. There is no need to, because there is no mechanical parts running. Uncheck that and see if that helps.
