U2312HM backlight turns off

Hello

I have the new U2312HM, connected to HP dock station with DVI cable. I noticed, that sometimes backlight of my monitor off on some changes. Sometimes it shuts off when the UAC Windows screen appears, sometimes does not take back the energy saving mode. Unfortunately, the problem is intermittent, I can't always reproduce. Monitor driver is updated to CD, my system is laptop HP 6730 b, updated graphics drivers updated to the latest version available.

When I used another monitor Dell U24xx, he had no such difficulty. Please suggest how to check that the monitor is good or bad.

My unit has been replaced by the retailer. New unit has no described default.

  • I have a DELL Inspiron 6400 running Windows Vista. The backlight turns off.

    I have a DELL Inspiron 6400 running Windows Vista. The backlight turns off when the charger is plugged after about 10 to 15 minutes. If I shine a torch on the screen, I see about the display is always. If I select change user from the menu start or stop / restart the machine, the backlight turns on and will last for another 10 to 15 minutes. I tried in safe mode and the same thing happens. Can someone help me with this problem?

    It could be the inverter Board or the backlight itself on the way to the outside. Whatever it is, it is definitely a hardware problem and it will take a good repairman to fix. You can contact Dell and see what they would charge to fix this, just to see if it would be more cost-effective to buy a new laptop or have it repaired. Because it is 5 years since it is manufacturing, you can be better to save your pennies for a new :-(

  • Bug: Pressing the missed call notification = backlight turns off

  • BlackBerry Smartphones backlight turns off after that I have a dial

    Whenever I have dial a number, the backlight turns off until the time wherever I disconnect. So if anyone wants any information about me that is stored on my phone, I can't just read from the phone. I got to wait for the call ends, find the info and then call them back!

    What is the use of call waiting if I can't see who's calling while I am already on another call.

    It's frustrating, I tried Googling, but have not been able to solve this problem. My bb torch is only 7 days old!

    Help, please!

    p.s. extending the duration of backlight in 'options' doesn't help either.

    Your flashlight is not only a smartphone, it's a "smart phone".  When you dial a number and place the phone in your face, the photocell detects this and turns off the display to save battery power.  If at any time you need to remove the phone from your face during a call (to add some numbers or receive another call, etc.), your phone reactivates the backlight, so you can see what is on the screen.

    If this isn't the case for you, remove the battery while your phone is on, then replace it (to do outside of a call, not on a call).  Try once more after that to dial a number.

    Let us know if that helps you.

    Hello

    It s a very strange problem. But I'll try my best ;)

    I noticed a similar problem on my second book. The display light didn't stop but the blue screen of death (BSOD) appeared and I could not continue my work.

    After a lengthy investigation, I found some useful tips.
    Someone told me that I have to disable HT technology (Hyper-Threading Technology) in the system BIOS settings.

    It's a key!

    As I remember the Satellite Pro A60 also supports this Hyper-Threading Technology.
    You can disable this function in the Toshiba HWSetup tool, in the CPU tab.

    Check it out and maybe it's a key as in my case.

    Dude good luck

  • OS5 stops Javascript when the backlight is off or time > 10 seconds - is this a problem for the WebWorks applications?

    I read that the OS5 browser stops all scripts once the backlight turns off, or if the script takes longer than 10 seconds to run. The problem is that the scripts will automatically restart (!). I really hope this isn't the case for the WebWorks applications, I can't have the app stop working if the backlight turns off. If the general development of BB moves towards HTML5 and JS and expects to have success, this kind of problem cannot exist.

    WebWorks for OS5 doing?

    No, this time-out does not occur for applications WebWorks... only for pages running in the browser.

  • BlackBerry smartphones turn off the Blackberry "BOLD"

    OK, I know this sounds stupid, but what is the correct procedure to turn off and restart the Blackberry "BOLD"? I hav tried holding in the key power, I get the stop message, press any key to cancel, I leave it alone and the backlight turns off, left alone for 10 minutes and then press the Power button again and the phone comes to life instantly, with the phone in the same position as when I wanted it off, i.e. it looks like it's just in mode 'sleep' as it is consumed in less than a second. I resorted to the battery, but it becomes laborious. And I cannot locate the info in the manual, it says just press the switch! I have also tried holding down until it seems to power off, but alas he always goes in mode 'sleep', please tell me what I'm doing wrong?

    Please mark the thread solved.

  • Equium A100 - 02L - backlighting will turn off by itself

    Hi people, I have another strange problem on a Toshiba laptop and I hope someone can tell me where to find a solution.

    The laptop turns on ok and post ok, screen is fully informed and nice n bright. Immediately after the POST the back light turns off, leaving me with an almost unreadable screen.

    First thought was obviously backlight inverter, the light was turned off in the bios also screen. It has been replaced twice with the same question.
    Next thought was the screen, also replaced with the same result.
    The only thing I can think of now would be sensor hibernation or the motherboard itself. I do not see the sensor cover on this model and I don't want to think about whether the motherboard until everything else is excluded.

    Any advice would be greatly received, thanks in advance.

    Hello

    Have you tried an external monitor to your laptop computer? It would be interesting to know what is happening there. Maybe the same thing happens here or not.
    Check this box!

    Normally I would also say that it s ups the FL, but you have already replaced it. By the way: you did it replace yourself and have you taken a Toshiba original spare part or another?

    A friend also replaced me the FL inverter but with Toshiba no spare part. He worked only a few weeks

    As far as I know you can disable it using Toshiba HW setup utility.
    On the desktop click Toshiba Assist (hopefully, you have preinstalled it on your laptop) > Optimize > Toshiba HW setup > check if the lighting of the tab is available.

    If Yes use OFF option and confirm with apply.
    This should help you.

    You can also check the advanced settings of the BIOS. If I remember well this lighting option can be also turned off it.

  • How turn off/backlight on Satellite A100 (PSAACE)?

    Is it possible to turn off the display and the backlight of the A100? There are 8 levels of backlighting, but none to turn it off. My previous journal had this feature, and I use it quite often.

    I assume you mean the brightness display function which could be resolved with the FN + F6 and FN + F7 key combination.
    No, it of not possible to completely disable the backlight.
    Something like that is not possible.

    Of course, you can set the time to the power of monitor off option in the Toshiba power saver.
    If you're away from you laptop and don t work on the laptop, the screen turns off automatically after several time.
