Light sensor ambient iMac 2012

My iMac has clearly a sensor of ambient light as I can see the screen change when turning on/off the light.

My question is about the 'normal' position of the brightness slider, because it seems that the brightness of the screen changes automatically relatively there where I put the cursor rather than an absolute position based on the ambient light.

Is this behavior as expected?

Thank you for your help

Yes. It recalculates a value based on your preferences and available light.

  • UHD monitor with ambient light sensor

    Hello

    I'm looking for a monitor with a light sensor, which automatically adjusts the brightness according to the level of light inside the room (similar to that of Eizo ev3237, for example).

    The resolution must be at least 3840 x 2160 (with the support of 60 Hz).

    Is there any monitor Dell equipped with these features?

  • Migrate messages from the Macbook Air to new iMac 2012 2016

    How can I migrate all my messages (text, iMessage) of my Macbook Air to my new iMac 2012 2016? I have a lot of messages on my laptop and I want to migrate them to my iMac just to have them for reference/memory later. I do this because I would like to activate the monthly updating of message on my iPhone, so he won't have to queue all my messages it years ago and I am also reformat my old Macbook Air. Is there a way to do this? Thank you!

    Messages and e-mail accounts and data are found in/Home/Library/Messages/and/Home/Library/Mail/files. Just copy the content to the same folders on the new computer.

    Or you can migrate your complete folder from the old computer to the new home. This can be done using the love at first sight between the two cable and on the new computer using target disk Mode use the Migration Wizard to migrate your application. It could also be run from a time Machine or another external backup drive.

    Migration will not overwrite any user account that has already been created on the new computer. MY simply creates a new Admin user account name. You will then need to switch to the newly migrated account.

  • Light sensor does not work

    I love my motorcycle G (from a 520 Lumia)

    My only problem is that when the brightness is set to auto, it does not change. Outdoors or indoors, there is no difference at all. I am under android 4.4.2

    When the value 'auto', the brightness will at least regardless of the situation.

    I download an app called Android sensor box and checked the light sensor module. It continues to show 2.0 luxuries, no matter if it's dark or full sun. It seems to be damaged material. Does anyone else have this problem?

    I thought so too. It works fine however take some time to adjust the brightness of the screen. I installed the app you mentioned, and it showed changes in brightness. Looks like it is a problem with your own only to the definition.

    I'm agree with @darp I not was able to recreate your issue, it is possible that an application it creates this problem, @SomeQuickAdvice start safe mode and run the diagnostics again or repair your phone with PCC

  • Latitude 10 st2 light sensor problem

    Hi forum,

    Yesterday, I installed the tool 'Tool Calibration of Rotation for motherboard replacement services' of the dell site.

    I was playing with the STMicroSensorHubTool.exe tool and was stupid enough to run it with "STMicroSensorHubTool.exe/als_cal-clear" and this seems also broke my light sensor.

    Unfortunately, I do not run 'STMicroSensorHubTool.exe /als_cal - get' before making clear, so I have no idea of the initial values.

    Currently, 'get' throw me the following error:

    C:\DELL\Drivers\8W4HP>STMicroSensorHubTool.exe /als_cal - download
    Please wait...
    Disabling device
    Please wait...

    Device allowing to the

    Unhandled exception: System.NullReferenceException: the reference is not the value of object
    an instance of an object.

    t CalibrationParameters)
    at STMicroSensorHubTool.Program.Main (String [] args)

    C:\DELL\Drivers\8W4HP >

    So what I'm asking is someone able to run 'get' on his Tablet and post the contents of the file "als_cal_coeff.txt" here so I can start with something and difficulty mine?

    Thanks in advance!

    Hello

    I forgot to update.

    > theroblog.com

    I think you're probably right, indeed, he spends some test mode the mode of operation of the detection mode, I get as before and managed to return to operational mode with / switches (I remember more accurate), but who did not solved my problem with backlight, but recovered automatic screen rotation which was also ruptured at a point.

    I do not did the thing with deletion/addition of Device Manager devices for the backlight, so perhaps that can fix the backlight for me.

    Fortunately, I was able to restore the functionality of the sensor. After about 2 hours of troubleshooting with DELL technical support, I said do a factory reset, and that solved problem with backlight.

    For the record I do tried to run 'STMicroSensorHubTool.exe /als_cal - get' (with sensor of lighting of work) to have a backup values, but I have the same error as above... There are clearly some bugs with this software package.

    Thank you!

    Lucas,

    According to me, which should solve it:

    Open system preferences and go to accessibility. Then select display in the source on the left side list, then check the box transparency reduced.

    It was introduced in this #15 post by TheUlser:

    It has been described on this page from Adobe:

    It may also depend on the monitor, as shown in the message #29 by Loncar in the same thread.

  • Ambient light sensor makes me crazy - x 230

    Hey. I have a x 230 with the 4000 series Intel gpu and I still get random brightness changes according to what is on the screen at the time and in what proportion of the screen it occupies. It's actually makes me crazy.

    The service of the ALS is disabled, all power plans are set to max performance and I turned off any sort of brightness/contrast setting in the Lenovo Power Manager and Intel settings. Everything is updated and the problem also manifests itself in the virtual machines running various flavors of Linux. I don't know if the solution of the problem in Windows 7 will fix the problem as it is the host, or I'll have to find a way to stop it on the clients as well.

    Anyway, please someone tell me how to kill. Makes me want to throw my laptop out the window when it's not just what I ask of it. This stupid ALS is set in so many different places and I clearly Miss whoever monte too the rest. Just messy. Help!

    There is a touch of Adaptive brightness as you see.

    Now change the attributes key from 1 to 0

    Close Registry Editor.

    Now, go back to settings of the power plan. When you change power plans/patterns. Now, there is a visible extra setting to turn off the Adaptive retro-lighting/brightness.

    Make sure this setting is disabled.

    Normally you can't touch this. But it is a way to unlock the setting.

  • Replacement HARD drive does not not in 27-inch imac 2012

    Hello apologies if this question has been asked and answered before.

    I've owned a Mac for many years, I'm comfortable shooting them to make any necessary repairs. My most recent Mac a 2012 13.2 27-inch iMac was a fusion player was not part of the HARD drive, the merger fell apart after the reconstruction of the merger and restore the system, the HARD drive failed this time, I could hear the sticktion in the drive so that was it. I had to put a replacement isn't a problem (so I thought) I did some research and bought a Seagate 3 to 7200 NAS drive to begin with, I thought I leave my machine on ground why not a NAS drive for the operating system.

    I had then the car adapter OWC with heat sensor, after getting the iMac apart that I replaced the drive, something I've done before on other Mac waiting for the machine to start with no OS instead, all show the iMac is the SSD it recognizes not the replacement drive at all no prompted me to format the new drive.

    I spent some time trying to figure out the problem to reset PRAM, put mode target to see if the disc looks for another mac, no luck in the terminal, the 'diskutil list' only would show only the SSD.

    I opened the iMac this time put in a Seagate HDD 7200 3TO standard before putting back together I ran the iMac with attached to another screen. It doesn't seem to matter what I put in the iMac in the car it does not recognize them, I was putting in old spare parts to see if it was a problem with the current firmware. I started thinking to the question could have been the SATA cable until I plugged the original drive in. Immediately the old disk could be seen and mounted perfectly in a last effort I got a model the same SSHD Seagate I checked is intended to be supported with this type of iMac still nothing ditch.

    I am at my wits end with this issue, it is as if the original is savvy to the system some how I read that 2009 iMacs had problem s similar I don't understand other iMac of the same model that the mine had the problem of fan speed and any player could be used. It aims to be a kind of firmware I am destined to load in the new drive.

    My options are very limited and for once I feel lost and let down by apple if it is worth $800 and $1000 to get the same 1 TB per apple apple player or as RESTful seems much this repair is already in me for $1200 (I have cracked the screen of origin)

    If any advice is much appreciated. My idea lasts is put back together and just start the operating system on an external drive to USB 3. The current SSD is too small for my image of time machine only 128 GB to restore to.

    A few thoughts here.

    Is it possible that the OWC adapter is faulty or well you don't connect it correctly? http://youtu.be/iWyJxnBM-Qu Unless I read wrong looks like the original drive is recognized and original SATA cable, but when you add the adapter into the mix, it does not work?

    Have you tried partitioning and firmatting the disk before you install it? Sometimes, who will do the trick.
