How to disable the screen of the laptop, while that connect the laptop to Tivi?

Please help me with this. When I connect to my laptop (HP Probook s 4525) to the TV by HDMI cable, instead of looking at the laptop screen, watching the screen great tivi. So I would only turn off the laptop screen (to save the battery/power).
Please tell me how to do this. Thank you and have a nice day.

Hello

With the laptop connected to your TV, press f4 (depending on your configuration, you need to hold down the fn key while pressing f4 ) to launch the release of the screen options, use the arrow keys to select "Projector" only, and press ENTER.

Kind regards

  • I don't have a message to tell me the image my takes up screen is set to full screen. How to disable the who and the fade slow when he goes to fs?

    In Firefox 42

    When a site like youtube when I make the video fullscreen it just melted slow useless when it does. And then tells me that it is full screen. I know that it is full screen for two reasons. One, I hit the button fullscreen. Two, the video takes up my entire screen. The message point. Use the fade. How can I disable them?

    To disable the fade, you can change these preferences of the topic: config page.

    • full-screen - api .transition - duration.enter: "0 0".
    • full-screen - api .transition - duration.leave: "0 0".

    You can open the topic: config page via the address bar.
    You can accept the warning and click on "I'll be careful" to continue.

    I do not know how to disable the warning, but it might be possible to hide this message with code to userChrome.css or elegant.
    This message is displayed for security reasons because a malicious script can switch to full screen mode and take over the entire window without noticing you (i.e. show a fake office).

  • How to disable the mode full screen

    The toolbar has disappeared. Can you tell me how to disable the mode full screen? Apparently this is going to give back me the toolbar.

    F11 activates / deactivates the mode full-screen.

    Versions of Firefox 3.6 + have a feature to allow the user to hide the Menu bar.

    Press the Alt key to temporarily show the Menu bar, then open view > toolbars and select menu bar, so it has a check mark.

    The F10 can also be used on most PCs to temporarily reveal the menu bar.

  • HP Probook 650 G1: How to disable the keys way to Probook 650 G1 running Windows 7, 64-bit

    I just bought a HP Probook G1, intel i7 650 - 4600 m, system BIOS 01.34-08/28/2015, keyboard review KBC 16.3 C version.

    ESC and F1 through F12 function keys seem to be in the Mode of action key (for example flight gives HP, F6 system information allows you to change the audio levels, etc.)- and I prefer to keep the standard functions of these keys (for shortcuts in Word and Excel, also for Express Scribe transcription software).

    I found Ctrl + Fn + the function key corresponding is workaround to achieve some (but not all) the standard functions - but which is cumbersome when used frequently. Workaround doesn't seem to work for the ESC key.

    I saw a few tips on how to disable the Mode keys on some laptops HP - eg
    http://support.HP.com/au-en/document/c02035108

    - and I have used this method on the previous laptop HP (e.g. Pavilion G6), but it does not work for this Probook. The configuration screen of the BIOS on my new machine does not seem to show the key Action Mode (or same System Configuration) as an option.

    I would be grateful for suggestions.

    Problem is now resolved, thanks to HP Technical Support phone line. Their tips were:

    * go to the BIOS Setup in the usual way (shut down, then power on, press ESC, choose F10 for Bios configuration)

    * Choose the Information System

    * arrow above to advance

    * Choose the Configuration of the device

    * Uncheck the Fn key switch

    * Save, etc.

    The corresponding option is more referred to Action Mode button for this model of HP laptop, at least not for the version of BIOS this Probook 650 G1 (worm 1.36, 25/04/2016).

  • Satellite Pro P - how to disable the hot keys for camera assistant?

    Is it possible, and how, to disable the shortcut keys for the camera wizard?

    The default keys interfere with shortcuts of Microsoft Office (Word) - for example Alt + F9 to show/hide codes field to turns on the properties of camera assistant, Alt + 10 screen settings of camera etc.

    I find this very frustrating.

    Hello

    Of course you can turn it off.
    You must remove the software from the camera in msconfig start up.

    So go to start-run-msconfig online online
    Go to the Startup tab and disable the camera software. Restart the computer laptop and that s all!

    Good bye

  • How to disable the charms to the point bar Windows 8.1

    I have a new HP laptop with Windows 8.1. I HATE the charms bar. It is very annoying. I have disabled the function of the angle of the bar charms appears is more that if I drag the edges of the corner, however, it pop again randomly. I'll be typing along and it will just pop up, blocking everything I am.

    I have absolutely no need of this bar of charms. In fact, the only thing that I used it for is to get to the option to disable them. However, on this laptop, which is not completely disable them... I tried to go to control panel mouse to turn them off, but this option is not available. However, I don't think it's the mouse pad, forcing them to pop up even when... I'll be typing along, not even touch the carpet of mouse, and all of a sudden they're going to pop up.

    What is the cause of this and how can I get rid of him? I'm getting rather desperate and sometimes feel compelled to throw this laptop out the window! I prefer my laptop HP Windows XP and has replaced only because XP is no longer supported... 8.1 window is one of the most frustrating systems, with that Microsoft has developed.

    Please help me turn off these dang for good things!

    UPDATE: I think I found the solution. I received this link a Microsoft Chat line employee. I followed the instructions and the charms seem to have disappeared... YAHOO...

    Here is the link:

    UDATE UPDATE: lol... I posted this below, but repost here... The solution given by the employee of Microsoft Chat line did not work... Well, it worked for a day, I arrested him for the night, and when I turned it on in the morning, the charms were back with a vengeance... Seriously, worse than ever, jumping constantly.  It was as if they were really angry...

    I went to Wally World and bought a $ 16 wireless mouse, which keeps the charm in the Bay... In fact, I think it's easier to use than the mousepad on my laptop anyway. I can use it on the arm of my chair on my laptop beside this mousepad, on a desktop (obviously), but the point being, unless I run the cursor at the very far right of my screen, the charms are hid...

    I have a business Web site, and all working on it, the charms have been constantly popping up as I tried to add images and descriptions. He took me seriously out of my mind... Everything took me twice as long to add, I don't waste time... I worked on it this morning using the wireless mouse and the charms bar jumped not once...

    Thank you Paul, but this link just tells me to do what I've already tried... When I tried to get responses on the Microsoft Windows site, it says that all laptops are different, and I would need to go the manufacturer of my laptop to tell me how to disable... So, I'm here, but nobody seems to know how to stop these things pretty darn... It is really ruining my experience with my new laptop... It's like the use of a laptop being shared with another person who constantly interrupts what I do...

    OPPS... while I was writing that I expect a person on the microsoft online chat to connect so I could ask them how to disable the...

    Rachel from Microsoft came... She sent me this link:

    http://winaero.com/blog/how-to-disable-the-edge-panels-charms-bar-and-switcher-in-Windows-8/

    I did what it said to do, and I'm typing this, no charms have jumped at me... Maybe it solves the problem (hope, hope).
