Detect when the screen goes black (standby mode)

Is there a way to do this?  OnObscured does not seem to be called, that makes sense.  I couldn't find anything on the forums about this.

Thank you.

Thank you guys.  In fact, I realized that onVisibilityChange is what I'm looking for.  It is called when the screen goes black and when the screen is popped.

  • Satellite U920T - the screen goes black when you drag the keyboard

    This morning, I turned on my U920T-10 days but the screen remained black.

    At first, I thought the screen was broken, but in mode 'Tablet', the screen became. Now when I slide the keyboard the screen goes black again.

    How can this problem be solved?

    Hello

    For me, it looks like a bad connection somewhere between the screen and the motherboard.
    This could be possible reason for failure to display while sliding in and out.

    I guess this can be resolved easily and I think that it is a job for a technician (authorized service provider). I recommend you contact the service technician in your country to get the laptop fixed. I hope that the warranty is still valid in order to repair for free.

    I hope that this can be corrected. I keep fingers crossed.

  • At the beginning; After the Windows Logo at the start, the screen goes black and a POWER SAVE MODE comes up. I must stop button. I can run the computer as I am now in Mode safe mode with networking.

    When I turn on the computer of gateway, the machine starts and the initial window logo starts and runs for about five seconds.  Then the screen goes black instead of blue and stays black for about 10 seconds.  A 'Power SAVE MODE' appears.  The machine is dead to all orders.  I have to stop by pressing the off button.  I can turn back and the F10 key to get in Mode safe mode with networking.

    I tried to reinstall Windows XP original but it would erase my files.  I tried to restore the last good configuration also knowledge.  That did not work.

    The change came after a Windsows update.  I have McAfee security and I asked Windows but could not use due ot a conflict. -C' is all this bad start.  Clues?  I use Negear.  No change when I hooked directly either.

    Botton line, I can run in SafeMode with networking; but it is slow and I can't make alll I have to do.  What does not load Windows?

  • Satellite L405D-11V - freezes and the screen goes black when you watch the video

    OK, so I have the Toshiba Satellite L405D-11V, I had a breakdown, basically, the computer freezes at any time and the screen would go black, with the fan and lights still ongoing, this could be at the start, or a few hours using the laptop, so I decided to ring Toshiba technology support and they arranged for my laptop to collect and be expelled for repairs.

    I was able to track repairs online via the tracking service and was able to see what they were doing to my laptop, he said that they have ordered a part, it was underway and the repairs are completed.

    However, I got the laptop back today, I turn it on, all right, I start using the cell phone that everything is fine, so I decide to watch a video on youtube, and it freezes again, so I turned off now pressed the power button, hoping he wasn't that a large, I turn back to and load the video once again it freezes and the screen goes black again, after that whenever I am watching a video or a game, it causes the computer to crash and freeze as before the repairs. So there is always a mistake, but I'm not sure what to do

    Its still under warranty, I bought the laptop from the Comet, but I really don't want to send the laptop for repairs again and find it comes back with the same fault, is it interesting sending distributed, maybe see if the comet will replace the laptop as its still less than a year to buy the laptop, or it'll just be useful to save all the hassle and buy a new laptop? If this fault happened to someone else, I could use you some help, and if someone could shed some light regarding what could be bad?

    Thank you

    Hey Buddy,

    You changed something on the configuration after you got your notebook back from repair? You update a driver, or something else?
    What operating system you use on your L405D satellite?

    To be honest it is really hard to say why it happens because technicians test to check if your laptop is running correctly.

    In my opinion you should try to update the display driver. Maybe it's the origin of the problem of s
    If this isn't the case, I recommend installing Windows from Toshiba Recovery disk to restore to factory settings. These parameters are pre-tested by Toshiba and should work.

    If you still have the problem, you must contact the technicians again. I mean you could track the online repair and according to your assignment, everything worked well during repair, so in my opinion he should t be a problem to contact guys exactly.
    Explain your very detailed problem. I think that everything can be clarified then. :)

  • Satego P100 - the screen goes black

    Hello

    If I turn on my laptop there is no problem. After maybe 5 minutes, the screen goes black and after a few minutes, he just a blue screen. Restarting the laptop. But now I don't have lines on the screen for the display of the BIOS and the power of Windows screen but during the operation. If the laptop is turned on after minutes the same, it goes black and then blue screen.

    BIOS and reinstalled system. nothing happens. I think that BIOS is flawed, because there are lines on the screen when I turn on the laptop again.
    If I leave the laptop for 15 minutes off the coast, it starts normally but aftern maybe 5 minutes it starts again with blue screen and other funny stuff.

    Now - what is someone the problem and a solution?
    I think the BIOS is a virus that destroyed. But I think that on a laptop, it is not possible to change only the BIOS. Because the update of it was ok but the problem remains.

    Thx for the answers and cordially

    I put t think the BIOS is defective. There must be another problem. All that you have done is just. Update the BIOS and the clean OS install are only option that you can do about it.

    Please contact the nearest authorized maintainer and let the technician to check your laptop. Let them to test the operation of the equipment using the service tools.

  • Satellite P100 - the screen goes black

    Hello

    I have a Satellite P100 and randomly, the screen goes black but the system continues to operate. I downloaded the latest drivers from toshiba, all power options the maximum support, run ccleaner and driver Sweeper to remove the old entries driver, re-installed the login screen of the mobo and nothing seems to work.

    The screen goes black sometimes when using windows but STILL turns black as soon as the ramps of gpu for example of playing a video or comparative analysis of the graphics card.

    Any help would be greatly appreciated.

    Model: Toshiba Satellite P100-PSPA6A-02NO21
    Processor: Intel Core 2 Duo T7200@2GHz
    GPU: Nvidia Quadro nvs 510 m
    Chipset: Intel i945PM
    HARD drive: Fujitsu 148GB
    RAM 2 GB
    Windows 7 Ultimate SP1 operating system

    Hey,.

    > ALWAYS goes black as soon as the ramps of gpu for example of playing a video or comparative analysis of the graphics card.
    This means that the graphics card is defective

    Theoretically, it could be an overheating problem too. Higher time can also cause a black screen. You should try everything that is possible to clean your laptop using the jet of compressed air to blow the dust from the cooling fans.

    If it doesn t help it seems to be a hardware malfunction but seriously a point would be interesting: have you noticed the same thing with preinstalled OS (Vista) Toshiba?

  • Continue to application play when the device goes into sleep mode

    Hey guys,.

    wondering if anyone knows how to maintain an active application when the unit goes into fashion watches?

    My application needs continue to work when the device goes into sleep mode if he went in that State by itself, or if the user put it to sleep.

    Yes I tried it on a physical device. It works, I promise you

    To clarify, here is what you will see when using KEEP_AWAKE:

    1 device shall not sleep when the application is currently active

    2. the device shall not sleep if the application is reduced, and you are in mode carousel

    3 device WILL sleep if the user switches to another application and full screen.

    In addition, another thing to know, if the unit is not assigned to the showcase mode, which is not by default, the audio stops when the user leaves your app. This is not related to sleep and is totally out of our control, but could be a good thing to add to your product details.
