My new S2440L face the problem of power outage

I have just purchase S2440L to replace my old S2340L. With S2340L, I have never have any problem of power outage but when I plug my new S2440L, it was goes black for a few seconds. The problem was random 10 minutes to 40 minutes. These two monitor was same HDMI cable (and work fine on my SmartTV too), PC same and even graphic card driver. I try to reinstall a fresh driver but still a problem. Is - it could be hardware related? Perhaps S2440L have a hardware problem or a S2440L need a more specific HDMI cable? Now I have any problem with my S2440L. the blackout has been occur when overheating circuit behind the monitor. I was watching about about on the HDMI port of overheating by googling and found that HDMI can fail if the (amplifier HDMI) circuit was overheated (I'm not have overheating issue on my old S2340L (rev.) A00). i sure as S2440L (mine is rev. A01) have material problem on HDMI and circuit surprise (lower part of the monitor) have very high temperatures. I hope you, Dell will be it is your responsibility that your monitor, S2440L have an overheating problem / high temperature and could be a HDMI port blackout curtains. It's bad for me avoid this problem by using the VGA port.

Thank you, ChozeriZes.

I just touch the border smaller surface compared to the top edge, it is very hot.

maybe only my S2440L have this problem...

Today, I remove my VGA card and the power cord, and reinstall the whole again, the problem in black often seem to not like it before summer. It's just a couple of times for that day.

Actually I feel fine with this monitor, both design and image, but still nervous about high temperature, it's may be the major problem in the long term.

Maybe I was too early to conclude everything... HDMI is a very sensitive matter, as I said in a previous comment, then I have some tests for my S2440L

-overclock grid power my VGA card around 2% and delete some fan of my system.

-find the new place for the power adapter avoid the heat. (I found this use of monitor LG IPS 1. 3a adapter 19V is perhaps)

Note: I use 750W Seasonic and power supply of 5V and 12V is pretty good (5.1V and 12.05V).

OK, now I need to close this thread as solved and and report this problem like power supply problem; in major relate.

"on monitor blackout curtains when use the HDMI port occurs when power on unstable system will also be able to rack in the House, heat and cable must use HDMI1.4 full spec for sure (if HDMI cable does not include with the package).

Best regards

  • Aspire Switch 10, new Version of the problem "does not start.

    Hello! I read through all the relevant threads and have not found a problem exactly like mine. I tried all the troubleshooting solutions but none worked.

    I had my Tablet for two weeks, works perfectly.

    My tablet was low on battery so I plugged it. I saw that he was in charge. Then I left it for about three hours. When I came back, it was off. Well, he seemed off. Except the blue light was turned on, the power button.

    I tried clicking on things, but nothing appeared on the screen. I tried clicking the power button... nothing.

    So I went online and verified solutions. I can't charge the battery, because of my model. I was able to turn off by holding the power button, but it will start. Instead, when I disable and click the power button again, the blue light (not orange) turns, but that's all. Just the light blue, no other indication of life.

    I tried to increase the volume, power, power + volume DOWN, home + volume, the pinhole reset button...

    They successfully all the 'turn it off', but nothing lights up it back.

    So, I tried one last thing, running down the power. After a while with the blue light on, warm up the screen. In fact, he got hotter than usual. But NOW, I'm afraid to keep the battery running down like that, because it "s more hotter and hotter. Is it dangerous for her to be too hot?

    Is there something else I can do?

    Thanks in advance! I loved my Tablet while he was fully operational, so I'd like a solution.

    normally, it will start the BIOS, reading your report, can be a dead LCD screen or the bad mother.

    If you are still under warranty, give Acer service a call.

  • Border in black screen HP Mini 210, screen shifted downwards - problem after power outage

    HP Mini 210-1000 actually it's HP Mini 210-1060 EV PC

    Some specifications:

    Display: 25.6 cm (10.1 ") diagonal WSVGA LED HP BrightView Infinity Widescreen Display (1024 x 600) SUBMISSION

    Battery has been dead for a long time.

    My display drivers and BIOS have been recently updated from the HP website.

    After a power failure and a reboot, the screen looks weird. It was moved about an inch down with a black border at the top, on which the mouse won't and the task bar is not visible, as is the bottom of the screen.

    When I go to the screen resolution in Windows by right-clicking on the desktop resolution is set at 1024 x 768, when I click on advanced settings, the monitor tab, monitor is set as a Monitor (1024 x 768 60 Hz) generic Non-PnP.

    When I change to 1024 x 600 it seems blurred and stretched vertically, but the screen is always shifted down with black border on top.

    When I get the Intel graphics settings I can make the same changes as in the dialog Windows (640 x 480, 800 x 600, 1024 x 600, 1024 x 768).

    In image format Options when I select full-screen (non-frontiere) the black border is fixed but always tense vertical screen but the screen is cut down with no visible taskbar.

    Graphics driver reinstalled so that some Type Monitor of windows drivers, nothing changes.

    When I turn on the laptop, the screen HP Quickweb appears also as a 1024 x 600 stretched vertically without black border at the top but will disable the display down.

    It seems that Windows and Hp Quickweb see at 1024 x 768 60 Hz display after the power failure.

    Before that, I had installed Windows updates, but nothing on the display drivers.

    I only got a point system restore leave on earlier that day (very low disk space?) but that did nothing.

    Guess it is a registry/driver issue since no pixel is bad and the black border on top is set in image format Options when I select full-screen (sans-bordure). Any suggestions please?

    So I restarted and the resolution has been set.

  • No automatic updates with the new motherboard. The adjusted settings as advised by your article, restarted the computer - nothing. Downloaded new copy, same problem.

    I get a notification that there is a new update for Firefox and click on it, but the computer is unable to connect to the server and download (if not internet connection works perfectly). I downloaded a new copy and the problem was not solved. I went to your site and set the parameters as indicated by your article, restarted the computer and it is still impossible to have an automatic update as before. (Before the change of the motherboard on the computer of authorized service everything worked fine).

    Try to remove FF from your pc and then it re-download the new version.

  • Windows Vista cannot access the internet, the link speed and Duplex negotiation seems to be the problem

    I have a desktop running Windows Vista Home basic and I can't connect to the internet through a local network, which is connected through a router (Belkin). Adapter type is Internet: Intel 825562V-210/100

    After consultations with the support of technichal society of router and my PC vendor, it seems that there is aproblem with negotiating the link speed. Here are some symptoms:

    I can access the internet if I connect the cable directly to the modem;

    Connected through the router, I can sometimes connecting to the internet if Imaually change settings of connection speed (10 / 100 Mbps, half/full duplex)

    All other PC connected to the network, using Win Vista and throuhg connected to the same router, have access to the network;

    If I connect my network cable to another PC, it will have access to the internet;

    The status of my PC seems to be 'connected' on the site of implementation of routers. The State of my connection is sometimes "Local only" sometimes "Local and Internet", but in fat, there is no internet access.

    I tried the following:

    Trouobleshooting under the direction of the technical support of the router and PC vendor.

    Update the operating system to restore to an earlier date, to restore to the factory settings; Reformatting my PC 2 times, (first internet worked for a few hours only); update the OS (by connecting directly to the modem); Turning off Win Defender, removing software antivirus. Reset LAN connection...

    Any suggestion please?

    New router solved the problem.

    Thanks a lot, especially Jack :-).

    Original title: ENERGY SAVING

    Hello

    Thanks for posting your query on the Microsoft Community.

     
    You did changes to the computer before the show?
     
    I suggest to remove the battery in case of a laptop and plug it in again and then check.
     
    You can run the troubleshooter of power to set your computer's power settings. The resolution of the problems of power check things as settings timeout of your computer, which determines how long the computer waits before turning off the display or enter the mode 'sleep'. These settings can help you save energy and extend the life of your computer's battery
     
    Open the troubleshooter of power
     
    See also How to use the registry to set preferred power
    Plan of
    following article and check if it works:
    When you configure power options for the active power plan in Windows Vista or in Windows 7, the changes do not appear in the Power Options item in Control Panel

    Important this section, method, or task contains steps that tell you how to modify the registry. However, serious problems can occur if you modify the registry incorrectly. Therefore, make sure that you proceed with caution. For added protection, back up the registry before you edit it. Then you can restore the registry if a problem occurs.

  • Flash Player 11.3.300.262 works only with Firefox. I think I found the problem.

    * Flash Player 11.3.300.262 does not work with Firefox. I think I found the problem.*

    Millions of people got off work & turned on there computers recently to discover that Firefox isn't playing videos or flash content. Like me, millions of people are randomly searching the Internet in an attempt futile and frustrating response. Unfortunately, many of these people will simply stop using firefox & consider a browser glitch, unreliable.

    This happened to me a few days ago. I started my computer and got a pop-up from Adobe saying that I need to update my flash 11.3.300.262 drive. I always thought that Adobe as being a reliable software company, so I clicked on it with confidence that things will take care even more fluid. To my horror, I have relalized that just after the update, my main browser, firefox has been destroyed. Then I went on the frustrating process of uninstalling, reinstalling, running virus scan, search the Internet like a lost child. I thought, "this is why I hate the update of things, because the updates always seem to change things you don't want to change, and there always seems to be a problem with updates." I generally update software month after release, because microsoft & all other software vendors always seem to not test it stuff properly before releasing. We must look a glitchy computer until the next update fixes it. Well, that is my rant. Now, let me discuss the problem I found.

    Problem:

    What I did, go to my menu firefox extensions, I disabled the 11.3.300.262 & I have reactivated the previous flash player. After that, everything worked perfectly again. Then one today (a week later), I turned on my computer and my firefox wasn't playing videos or flash content again. I went into my menu parts of firefox again, and I discovered that my old flash drive has been removed & this 11.3.300.262 new glitch had been activated. Why adobe feel the need of in my computer & automatically delete and update my flash drive. Now, it does not work. It IS REALLY FRUSTRATING!

    The question that I discovered:

    "RealPlayer" is the most popular video show & it's installed on millions of computers. For some strange reason Firefox doesn't want its users to use Real Player. Specifically the RealPlayer Record Plugin 15.0.2. I also discovered that my Plugin 15.0.2 Record of the browser has been disabled automatically when the Adobe 11.3.300.262 is automatically updated too.

    -Maybe this could be because of some conspiracy of copyright law to stop people from downloading videos from the web.

    -Maybe firefox wants people to use it download add-on instead of RealPlayer downloader.

    I don't know what ther reason. But what I know is no one will remove it RealPlayer to computer there is just to use FireFox. We can just use Chrome or Internet explorer. I took advice of people with disabilities the Extention of RealPlayer, FireFox and Adobe. I also went in my RealPlayer preferences options, but there is no option to disable the download of FireFox for registration. BECAUSE I have ALREADY DISABLED THE add-on menu FireFoxes.

    Solution:

    Step 1: Adobe needs to update all computers with the previous flash player. In this way we can choose to activate the previous flash player in our FireFox. or wait for a new update fixes the problem with firefox.

    Step 2: Adobe & FireFox need to get together and go back to the drawing board. They need create an update that actually works on computers with of Real Player installed on them. I don't like that the company made the update. All I care about is if it works. Thank you.

    Oh yes, Im market FireFox 13.0.1, Windows 7, computer HP, Real Player is up-to-date.
