  I understand that you get a white screen when you turn on your system. I'm happy to help you with this. I would recommend that you start with searching through this page. Since the construction in and external display do not respond, I would start with the displays.

  Hi johnrodden,

  Thanks for posting in the Microsoft community!

  I'm sorry to hear that you have a problem with the external monitor.

  1 turn off your computer and unplug the monitor, but leave the mouse and keyboard connected.

  2. connect the appropriate video cable from the video port on your computer to your TV.

  3. turn on your TV and set it to the input that matches the video port connected to your computer. You may need to refer to your TV user guide for instructions on how to do it.

  4 turn on your computer.

  You should see windows displayed on your TV.

  If you do not see an option named multiple displays in your display settings, then Windows isn't detecting a second monitor plugged into computer. Or else, it does not detect an external monitor plugged into your laptop. When Windows detects this monitor, it will appear in the drop-down list next to the screen. If you do not see that what listed there, try click on Detect.

  Make sure that the monitor you want to extend your desktop is turned on and plugged on the video appropriate port on your computer. You may also need to select the correct source labeled on the controls of your monitor to ensure that the monitor is using the correct video port. For more information, consult the manual of your monitor or go to the manufacturer's Web site.

  Please set up multiple monitors once more, referring to this article:

  Set up multiple monitors

  http://Windows.Microsoft.com/en-us/Windows-Vista/set-up-multiple-monitors

  Refer to the mentioned suggestion as "what can I do if Windows can't identify the additional display?" in this article:

  Multiple monitors: frequently asked questions

  Reference:

  Please report if you are still having the problem. I will be happy to provide you with the additional options that you can use to get the problem resolved.

• The display on my laptop is not on.

  The display on my laptop is not on. At the start, it of on a second and then darkens. The display is always there. I can connect a secondary screen to the laptop and it works fine. It makes a weird sound (like a boing sound) when the screen will Dim. When you close the laptop and then open again the screen lights up again for a second, then goes dark. I tried uninstalling and reinstalling the video drivers and that didn't work.

  This indicates generally the backlamp (s) of the screen failed. These lamps shine at the back of the screen and lights by behind, making it visible to you.  When they fail it is often what they do - turn on for a second or two and then turns off, you can still see the screen but only with extreme difficulty.

  They are not something that can easily be replaced, you will need to take your laptop to a Service Center for repair for assistance.

  You have the screen image out to another monitor (one that is not plugged in fact). How you pass to the internal laptop display varies, but most cell phone companies make a combination of keys, such as Fn + F6 or something.  Looking for a symbol that looks like a monitor.  It is usually color coded and requires activation of a Fn key.

• How to adjust the brightness of the screen of a laptop computer from HP (HP 6730 s)?

  Original title - Windows 8

  My daughter recently bought a new laptop (HP 6730 s) and bought and has Windows 8 installed on it.  She doesn't know how to adjust the brightness of the screen.

  That's what she said "how to adjust the brightness of the screen on a laptop HP 6730 s running Windows 8? The internet is not give me answers. There is no "graphics properties" option when I click right on the desktop, nor is it a brightness slider when I go into the truly enigmatic Control Panel. ".
  I tried searching via the Microsoft website for an answer.  The only answer is for Windows 8.1 - she tried the steps to adjust brightness as given for Windows 8.1 However, it does not work for Windows 8.
  Could you please help and let me know how to get to the setting of the brightness, on his laptop screen, for Windows 8.
  Thank you in advance.

  If it is possible to do, it's a feature of his laptop, not of
  Windows. She should contact HP or look on their website.

  4 IPad keeps going to power off of the screen, the screen is cracked but do not know if I need to replace the screen button or power?

  Press the sleep/wake and Home buttons and hold for at least 10 seconds.

  If this is not enough, take a look at these articles Support from Apple:

  If your iPhone, iPad or iPod touch does not respond or does not turn on - Apple Support

  Use iTunes to restore the iPhone, iPad or iPod to factory settings - Apple Support.

  As a final step, try recovery mode. Turn off your unit, then plug it to your computer with the hold home button. Hold down Home button until you see the logo on the screen of your iPhone iTunes. After that on your computer, you should see the iTunes window saying that your iPhone needs to be restored to factory settings. Click Restore.

  If these steps do not work, contact Apple and ask for help.

• Laptop computer connection directly to a projector and cannot see the screen of my laptop

  I'm trying to figure out how to display the screen of my laptop via a projector and also be able to see the screen of my laptop.  When I hit the function key for display on the big screen, my laptop darkens.  I found a post on this forum on the connection of additional views or projector (Set Up Multiple displays). When I go to Mobile PC and display to choose settings listed in the answer (mirrored, extended, etc.) aren't there.  My laptop is running Vista Business Service Pack 2 and two weeks.  Thanks for any help you can provide.

  Hello Shawn,

  Thanks for posting on the Community Forums of Microsoft Vista.

  It should probably be shortened on your laptop keyboard to turn on the visible screen (for example Fn + F5). Try these until you can see the image on the laptop monitor.

  Also, follow the steps and try to set the screen parameter as follows:

  (1) right click on the desktop, click Properties, and on the display settings, choose monitor as your main graphics card 1.

  (2) setup that monitor the as a 2nd external display (projector).

  (3) click on apply and Ok.

  Restart the computer to see if you are able to see the screen on laptop and projector.

  You can also check with the computer manufacturer to check if they have additional parameters to be changed.

  It will be useful.

  Thank you and best regards,
