HDMI is not send the signal on external monitor once the laptop awakens from his sleep

I have my TV as a second monitor for my laptop. I connected via HDMI. Once I leave my laptop a little past in mode 'sleep' and the screen loses the connection. Once I wake up the laptop, the monitor is not turning back on my desktop. It remains off. I disconnect and reconnect the HDMI and it does nothing. During this operation, my laptop screen flickers as when he connects to it, but nothing happens. My TV does not receive the signal, but the laptop says it's connected. What can I do to fix this? Thank you

PS. I have to restart my laptop each time to allow to work my external monitor.

    My laptop (Dell Inspiron only 3 months old) is displayed on an external monitor, but not on the laptop screen. I am running Windows 7. It was running and display very well last night. When I turned on this morning the monitor lit up but show just a gray-white screen and no office. When I attached an external monitor, I could see desktop and all other programs and Windows 7 routines seem to work very well.

    Press the Windows logo key and the p key, and then set up the PC to display on the built-in monitor only cycle through with the arrow key.  You can make this Store if you want - key Windows-p, right arrow once, paused for a few seconds & the laptop monitor should then appear normally.

    You can do so at the end of each session using the external display while you are ready for the use of the laptop on its own later.

  • Firefox could not download the search plugin from

    I installed Firefox 24.0 recently and I am trying to install open www.youtube.com youtube Search Engine by clicking on Add "YouTube Video Search" in the search bar, but I get the following error message:

    Download error
    Firefox could not download the search plugin from:
    http://www.YouTube.com/OpenSearch?locale=en_GB

    What is a Firefox problem, or a youtube error?

    Thank you for your response.

    I don't want to install addon for youtube search. I just wanted to know if I can install the search engine for youtube as before.

    After a few readings on the internet I found that the search engine is described by a small XML file which is available through a link on the page. All other pages with operation generates the search engines like Wikipedia or IMDb content is XML refers to XML file. But the link to youtube opensearch descriptor points to an opensearch.osdx file.

    I don't know if it's the extension, or if he did not support tag inside but Firefox is not prepared to handle it and add youtube to search engines.

    I found this page: http://www.tobtu.com/customsearch.php I copied the relevant tags in the fields of seizure and added YouTube video Srearch. Now, it works fine.

    But the question remains: is it Firefox that can not handle the descriptor of opensearch sandard of youtube or youtube.com which provides a defective descriptor?

    Could not import the music downloaded from iTunes for Windows Movie Maker.  He plays in Windows Live Movie Maker and plays on my computer.  Cannot find the codec. Tried the solution to this same question and in help.

    Hello
     
    Some audio and video file formats are not supported in Windows Movie Maker and cannot be imported. However, if you have a video or audio file that is not taken care of, you can use a non-Microsoft video editing software to convert the file into a format supported by Windows Movie Maker, and then import the video file or an audio resulting in Windows Movie Maker. Some files also require you to install a codec before you can use the files in Windows Movie Maker.
    Note: The use of third-party software, including hardware drivers can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the use of third-party software can be solved. Software using third party is at your own risk.

  • External monitor is no longer wakes from sleep (10.11.2 updated)

    I have a LG external LCD - LED group connected to my Mac Pro via HDMI 2013.

    No problem with no display at all before sleep... but since the 10.11.2, update it just don't wake up from his sleep and I have to force a reboot. I've since turned display sleep off options and I now use a screen saver protected by password instead (of security) and simply turn off my screen with the power button.

    I had this problem too with the Beta 2 and Beta 5 from 10.11.2. Both times I started 10.11.1 Time machine, hoping it would be fixed in the final version.

    Before that everyone says, the following link is not welcome... I has not come down in the last shower: If your Mac does not sleep or wake up when expected - Apple Support

    It's certainly something that has changed in El Capitan 10.11.2. I now have a beast + $10,000 a computer that can not put its own screen of sleep

    Exactly the same problem with my mac pro and panasonic plasma hooked up via hdmi. Worked fine before the update. Now, if I turn off the monitor, I have to reboot to get the screen to display an image, once it comes back on.

  • Yoga 900 wakes up from his sleep when picked up by the short edge

    I want to show Aproblematique I had with my 900 Yoga to see if others have had similar problems.

    I discovered this when I put my Yoga, (who was asleep) in my backpack and then subsequently noticed he was awake. It took me a while to understand what was going on, but I finally decided that she had nothing to do with the backpack.

    My 900 Yoga wakes when picked up by the short edge (as I have done to put n my backpack). You can see in the video:

    Yoga 900 wake when picked up

    (BTW - I'm not press the laptop, I'm just taking it as it is necessary to pick it up by the edge.) Press the lid and there is a pressure on the rise on the bottom. It is the pressure on the lid which seems to be the cause of the laptop to wake up)

    Note that Lenovo has been great and sent me a replacement laptop. But I'm curious to know if others see this same problem.

    Is this a common problem with 900 Yoga?
