• 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.

  at STMicroSensorHubTool.Program.LightSensorCalibration (CalibrationParameters_
  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.

  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!

• 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.

• Light sensor ambient flow 8.

  Is flow 8 supports, ambient light sensor?  Changing light/brightness manually, it's really annoying...

  Hello, unfortunately 8 Stream doesn't have an option of automatic screen brightness. The fastest way to make the brightness adjustment is to tap the icon at the bottom of the screen.

  can I use my light as a charger for my battery sensor? ... If it isn't... what happens to the current generated from it?

  @AbdelrahmanHamoda

  Could you develop, how you try to use the "light sensor" as a "charger"? It is not a solar panel

• 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?

• Screen light sensor

  Hello, I have a problem with the Z5 perhaps compact cause automatic light, the sensor, cause sometimes the screen is quite dark same Sun and other times she keep changing the lighting... and that make it difficult to see the content. How can you trouble? Is this normal? Thank you

  Hello!! I watched the Adaptive brightness Meanwhile and I must say that it works really well, but it is so sensitive that any movement in a different direction where is the difrent brightness changes, so if I'm in a place with a few different intensities of light I need to put the mobile in the direction it's better (as I am I have a place with the light above me) (, but behind it is less the sensor takes a bit less, I hope it's a good explanation). The problem may be known as resolted on my part at this time Cheers

• Satellite Pro A300 PSAGDE Touch pad and fingerprints fingerprint sensor problem

  I have been runing Windows Vista on my Toshiba Satellite Pro A300 PSAGDE. Because my original Windows Vista key has been blocked I did a system recovery CD Toshiba vith XP. Everything work fine except the fingerprint sensor and the touchpad. Manager access suite said he couldn't connect with equipped and the driver touch pad in the taskbar icon shows but it seems to be inactive. The touchpad does not work even though I have pres FN + F9.

  What should I do to save this problem.

  Sory for my bad English, I just form Slovenia, I hope you understand.

  Somehow the material is not properly recognized.
  It will be interesting to see if the fingerprint sensor and touchpad may work with Vista preinstalled originally.
  I think that Alex is right. Contact the nearest Toshiba service provider and ask for help. They should check the functionality of the hardware.

• 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.

• T61: cover and non-functioning lights switch problem

  My T61 (type 6465) is coming for three years and has recently developed some minor but annoying flaws. The main problem is that the most reliable laptop will remain suspended: closing the lid does not have to be suspended in the first place and if I use Fn + F4 to suspend, it seems that clutching the back edge of the laptop (that you could do to pick it up and put it in a bag) cause him back on the suspension. Accordingly, I found the cell phone on when you remove it from my backpack, even if I was sure that I had hung before storing.

  The other symptoms, is that some of the green lights have stopped working. Namely, the green lights of power, battery, caps lock num and caps lock seem to have stopped running, but wireless, hard drive and activity to suspend lights continues to work. In addition, the orange battery light works very well.

  Other that the system continues to work perfectly: the battery is still good and maintain the load, the power supply charges the battery and powers the system properly. Power management applications show the correct information about the power status of the system (i.e. on current AC or battery-operated).

  I try to work if this is likely to be a hardware failure or a software problem initially. Has anyone seem to similar symptoms, or may suggest that the problem could be based on my description?

  See you soon,.

  -Mark.

  non-functioning lights is most likely a hardware problem.

• Stop the engine when detects digital impulses of the reflective light sensor

  Hello

  I am doing my school project and I managed to make the deepening of the engine via digital port of the USB-6008 by setting the Boolean value of output in a while loop with use cases, but now I faced a problem because I have to use it with a reflective sensor and stop the engine when he feels a digital pulse. The sensor is configured as a counter using PFI0 on the USB-6008 with a circuit that will send in a digital pulse for data acquisition.

  How to stop the engine when the detector reflecting is blocked, and then start the deepening again when it is not blocked

  Thank you

  The top spot is always implemented as a counter.  You must change the DAQmx create channel as a digital input and the DAQmx interpreted as a Boolean variable digital 1 channel 1 sample.
