Problem dual screen ' after working for a while, the screen of my laptop turns off.

Original title: Problem dual screen

I use two screens (laptop screen and separate screen) to work. Windows 7 operating system. After working for a while, my laptop screen goes blank as if he goes to the standby mode. The monitor never goes out. Is - this cos win 7 does not support the spl double screen laptop computer and monitor at the time of amse?

Support COMPUTER told me he can't stand not and laptops are not designed to function as a two screens? Please notify.

Portable computers support two monitors. The problem may be caused by two reasons:

1. incorrect power setting.
2. the problem with the drivers.
1. you can download and open Microsoft Fix it for the question.
2. update the display drivers. If no update is available, uninstall the drivers (and software), restart the PC, install the drivers (and software), restart the PC and then check.

    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.

  • My laptop turns off after that it lags behind. More details inside.

    As the title says, my laptop turns off after that it lags behind. He accused the sound of something that fate of my speakers started his strange. Sound like a blur with tell them no matter what. Then my laptop everything is slowing down and there is a black screen. After that, it takes a few minutes to close.

    It happens every time I play a video. Not all the time but most of the time. And whenever I try to play a game (Warcraft III to the PvPGN server) I can play, then he gets really laggy and my computer starts with fuzzy noise and turns.
    Sometimes, he says something about iPoint.exe

    Please explain in a less complicated way due the fact that I'm not really good with technical equipment.

    Hello

    I bought this laptop there is an upgrade to a week of the dell studio 1558 and it is most powerful spec wise, and I will admit windows 8 makes things a little strange, but I have problems with the laptop:

    Sometimes the laptop works slowly and some applications such as chrome and steam and Skype just stop working for a while and sometimes require applications to be reset to zero before they will work again and chrome has developed a bug that doesn't let it open if I click with the button straight on her and say to open a new window

    The without wire will fall randomly and won't open the Connections window, the devices show as being active, but cannot enable or disable it or find or even open wireless connections menu for connections to find this can be solved by a system reboot... I have updated the drivers for the wireless to the most recent for the Atheros card

    He do not restart, shutdown or sleep when asked to do the screen turns off, sound as his preparation to close and say with the darkened screen suspended in the closing state until he either cut his own power or I hold the power button to force it to turn off.
    I have updated drivers available on the Toshiba site like all the AMD drivers say they are incompatible

    Help would be appreciated, I don't want to send it back or to try to get back into windows 7 or something dramatic

    To me that sounds like a large number of programs, applications, and processes are running in the background.

  • MN - 700 router worked for a while (over 3 years) without password. How to set a password? __

    MN - 700 router worked for a while (over 3 years) without password. How to set a password?

    MN - 700 router worked for a while (over 3 years) without password. How to set a password?

    This is a pretty old router, but documentation is still available from Microsoft:http://support.microsoft.com/kb/902461 the 'Guide' is more complete, but the "Base Station Configuration Guide" will explain how to configure the router.

    I guess what you mean by a "password" is the password for the wireless encryption (there is also a password that controls access to the router configuration utility). The following are the basic steps to configure wireless encryption (see the documentation for more details and screenshots):

    1. utility access to the router configuration, preferably with a computer connected to the router with an Ethernet cable (if you change your wireless security, the parameters using a computer connected to the router by wireless, the connection will be abandoned as soon as you click APPLY).  Open a web browser and type 192.168.2.1 in the browser address box.  If you have not changed the logon password, enter 'admin' (without the quotes, all lowercase).

    2. click on the "Security" link on the home page of the configuration tool, then "Wireless Security".

    3. Select the "niveau_chiffrement" in the combo box to "256-bit WPA - PSK (louder)" - unless all of your wireless devices are so old they don't support WEP (unusual for a wifi device years less than 5 or 6).

    4. in the box, type a password (between 8 and 63 characters), and then click 'apply '. at this point, you will be disconnected from the router (and the Internet) If you did the above changes using a computer connected to the router WiFi.   Write the password in a place where you don't forget.

    5. close router configuration utility.

    To set up your wireless computers:

    6. open network connections (start > run > ncpa.cpl > OK)

    7. right click on your wireless adapter icon and select Properties.

    8. click on the wireless networks tab

    9. make sure the box at the top next to "use Windows to configure my wireless."

    10. in the list of "Preferred networks", select the entry to your router (your network name), click on 'delete '.  [This deletes the entry from your wireless network WITHOUT a password, so that you will be able to add an entry for a network with the same name WITH a password.]

    11. click on the view wireless networks"" button.

    12. the name of your network should appear in the list of wireless networks.  Select it and click "connect". When you are prompted for the password, enter the WPA password set in the router configuration.

    13. open a web browser and confirm that you can access the Internet.
