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 problem

    Hello. First post here. I had problems with my sensor of ambient light in the night - in total darkness, the screen refuses to adapt to its brightness. The Adaptive brightness setting only works when there is a light source or if I reboot my phone. Which is problematic for the cold winter nights when I don't want to leave the blankets. My phone is running Android 5.0.2. Is there a fix?

    Contact the customer service and the Assistant advised me to clear the cache to get rid of all junk from previous installations of Android. Since it is in the middle of the day, after having done that, I lock myself in a closet as a small child and tested the Adaptive brightness. It seems to work so far! And my pitcher is smoother too? I'll be sure to do so before resetting the phone entirely, in the future. Thank you Jenny!

    (Wao, motorcycle customer service iz pretty gud!)

    CLEAR THE CACHE:

    1. with the phone turned off, press the FLIGHT BUTTON down for 2-3 seconds and then release the POWER button.

    2. the unit will display the different BOOT OPTIONS

    3 use the FLIGHT DOWN to SCROLL to the recovery key and the FLIGHT UP key to select

    Tip: If the device restarts, you may have been waiting for a long time to make a selection, you will have to start the process.

    4. the unit will display the Motorola logo and then the Android in distress (with exclamation point logo)

    5. press in and hold the FLIGHT upward for 10 to 15 seconds. While pressing the FLIGHT UP button press and release the POWER button

    Tip: You can try this step, holding the phone in landscape. If you're stuck on step 6, try a forced reboot by pressing the Power button and the key low-flying and start the process again.

    6. the unit will display additional menu options (text will appear in BLUE)

    7 use the FLIGHT DOWN key to scroll through the options to clear the cache partition and the POWER button to select this option

    8. the unit will then perform the wipe partition

    9. the unit will restart and begin the normal diet of the sequences.

  • Latitude 10 - ST2 Dock HDMI problems

    I just pulled up on my docking station and found that it worked perfectly out of the box.  Unlike some others who have had problems, I felt lucky until I tried to get the HDMI to work with my Dell monitor.

    It's about that simple, the monitor does not detect a device and the device does not detect an HDMI monitor.  I've updated the BIOS and drivers Intel for the latest versions from today and still nothing.  I'd appreciate any advice or experiences like mine that could help me to get this resolved.

    Quick update on my situation.  I was able to get the dock running after realizing that you cannot convert HDMI in Display Port, only the opposite.  My monitor DELL Professional is not HDMI, there a display Port.  Not sure who came up with this idea, but it seems that HDMI is a standard that is good enough to not have to create another.

    In any case, I was using a HDMI Display Port adapter--> and after reading upwards, is that you can convert only the signal in a way.  Turns out the other way, of what I was trying.  If you have a video card that has a display out Port, you can use this adapter to convert to HDMI.  I do in fact with another computer of mine.  However, if you have a monitor with a Display Port, you can not convert HDMI Port to display in this way.

    Anyway, I ended up finding a DVI switch and turned the HDMI/DVI monitor and everything works fine.  It's a little weird for the signal on the screen, but as you mention, if you start the camera on the dock, it seems to detect the signal.  Without that, it seems random as to if the signal is getting sent to the monitor.  Sometimes, the monitor just says not: 'no signal' until I have restart the device.

    Thank you all for the contributions.

  • Dell Latitude 10 ST2: Screen very dark after the Windows Update 8.1 & gameplay of Diablo 2

    Hello community,

    I just got a new Latitude 10 ST2, and I really appreciated the help until after that I updated for Windows 8.1 and played some Diablo 2. For some reason, my brightness is now always very low, regardless of whether the Adaptive brightness in my power management setting is enabled or disabled. I can manually change the brightness, but it has very little effect. It seems that the maximum brightness is really low for a reason any.

    I don't know if Diablo 2 has nothing to do with this problem, but I though that I would include it here because it uses very outdated graphics techniques that seem not very compatible with Windows 8.1. I had to change the compatibility settings of the game executable for Windows XP Service Pack 2, force them to run with 16-bit colors and also to disable the composition of the bureau. After closing the game, icons on the desktop still seemed a little wide (they looked rather 16-bit color and had some weird artifacts) and I had to restart the tablet to correct. After the reboot of the Tablet, the desktop icons were back to normal, but my light issues began to arrive.

    My first attempt at solving this problem was in the shape of the tablet. I used my USB stick that has the factory settings on it to format the Tablet and reinstall Windows 8. The process was a success, and I had no problem of brightness either. However, after the update to Windows 8.1, then by restarting the Tablet, my issue with the brightness came back.

    My second attempt was to try to update my drivers. I ran the auto updater provided with the Tablet, and it updated my BIOS. Unfortunately, it has not fixed the problem at all. Then, I took a look in the BIOS and found levels of brightness in the video section. The parameters are the following:

    Brightness on battery: 7
    Brightness of AC: 15

    I've tried corresponding to the brightness of the battery at 15, but it has no effect. The light problems don't occur that the Tablet is connected to a power outlet or not, I wasn't really that surprised that it didn't work. A maximum brightness of 15 is normal? (what is a percentage?) I don't want to change these settings without knowing exactly what they represent to avoid damage.

    My third attempt has updated the chipset drivers which includes the video driver. I installed the chipset driver and suddenly after that the screen went black a few times during the installation of the brightness has been completely restored and colors looked nice and bright again. However, when I rebooted the Tablet I found that the problems of brightness was back. Very rarely when I restart the Tablet, the brightness is normal again, but it is super rare. A subsequent reboot simply results in brightness problems return immediately.

    A few other things worth noting that come with the light problems:
    -All color gradients are not smooth. You can very clearly see the differences in brightness when a picture goes to a light color to a dark like a lot of buttons in Windows 8 start menu. It reminds me a lot of 16-bit color;
    -Whenever I try to change the display settings in the Intel Graphics and Media Control Panel, nothing happens. No matter how much I fiddle with the brightness, contrast or gamma, nothing changes, even after you apply the settings.
    -Diagnostic in the BIOS tests said that everything is OK;
    -The complete diagnosis provided by the PC Dell Diagnostics program showed that each test passed successfully.

    I really hope that someone can help me with this problem. The screen is also very dark, it makes it quite difficult to use tablet. Thank you!

    Kind regards

    StevenD91

    Thanks for the reply! After much trial and error, I discovered that my graphics driver has been be corrupted by AVG 2014 somehow. After yet another format and reinstall of Windows 8, but without AVG 2014 this time, everything works great! : D

  • 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.

  • Latitude 10 ST2: Wifi / boot SD issues

    Hi all

    I just got a Latitude 10 ST2, which came with Windows 8 Pro installed. I'm having a few problems this long search has always been able to resolve.

    First of all, I can't connect to our wireless business. The search led me to Microsoft KB2749073, which describes in detail an incompatibility between Windows 8 pilots and our Cisco access points. A single action, he recommends is to upgrade to Windows 7 drivers. So my question is: where to find Windows 7 drivers for the device wireless in Latitude 10 ST2? (She appears as a Broadcom 802.11abgn SDIO)

    Secondly, I was wondering if it is possible to boot from an OS on an SD card. I read a few guides in this area, but they were written for the Surface Pro and do not seem to apply to the Dell. I tried taking top flight and get in this menu, but it does not contain an option for the SD card. There is an option somewhere that I'm missing?

    Thanks for reading!

    The Latitude 10 comes with active secure boot.  If you disable this option and you enable start inherited, you could be then boot from an SD card.

    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
