System suddenly turn off when the external display is connected

I have problem with my system. every time I connect a projector or a HDMI my system stays for a short time and shuts...

Hello

Thanks for posting your question on the Forums of community of Microsoft.

  1. The computer completely off, or only the monitor turns off?
  2. You get an error message or a blue screen while the system is turns off? If Yes, what is the exact error message you get?
  3. What is brand and model your computer?
  4. Apart to plug the projector, does this problem occurs in all other conditions also?
  5. What happens when you try to turn on the computer later, with a projector connected?

I suggest you to check if the computer shuts down completely or only the monitor turns off. If the computer shuts down, the problem may reside with the graphics card driver that fits inconsistent or has become unstable or corrupt. Therefore, I would suggest trying the following steps and check if the problem persists.

  1. Open Manager devices by clicking the Start button, click Control Panel, click system and security, and then, under System, clicking Device Manager. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.
  2. In the list of hardware categories, find the display adapters and select the device driver you want to update, and then double-click the device name.
  3. Click the driver tab, click Update driver, and then follow the instructions. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.

For more information, visit the below mentioned link:

If you are not able to update the device driver via windows update, you can visit your computer or graphics card manufacturer's Web site and download & install the latest driver. Or contact the manufacturer of your system to do.

Hope this information is useful. If the problem persists, please post back with answers to questions for assistance, we will be happy to help you.

  • Satellite A60 turns off when the only power is connected

    Hello

    Recently my original adapter has stopped working and I bought a new one. However, the problem with this new is that when it works perfectly until you hear the windows that open sounds and then she just turns off. But when I plug the AC with the battery connected to the laptop, it works fine. It's just that it will not correctly work with just the AC is plugged.

    HEY Fan Wai,

    It seems that your new adapter cannot supply enough current to power your laptop when it is under load. I suggest you check the rated power of the new adapter agaoinst those of the original.

  • Compaq 6910p - wireless adapter turns off when the ethernet cable is connected

    Hi all

    Then, when I plug in an ethernet cable (connected to a router), my wireless adapter turns off.

    He immediately turns on when I unplug the ethernet cable.

    It isn't really a problem, either connection will provide my needs of networking, but it's just weird and I don't like it.

    Using Win7 Ultimate 64 bit.

    advice would be appreciated.

    Hello:

    This is the default setting to save the battery.

    If you always want the wireless on, go into BIOS > Menu of device Configuration and activation to deactivate WLAN-LAN.

    Any help will be greatly appreciated.

    Hi aloum,.

    (a) what kind of mouse you are using?

    (b) the left button of the mouse seems to be stuck or it does not meet the click? This only happens with certain applications?

    Step 1: Test the mouse on another computer or another mouse on the test computer

    To determine whether the mouse or the computer is defective, follow these steps:

    1. test the mouse in question on a system that works, you know. If the problem appears to follow the mouse, you may need to return or replace the mouse.

    2 test a mouse you know is working on the computer in question. If the problem seems to stay on the computer, then the problem is most likely related to the software.

    In regard to the battery not holding charge

    Battery problems are often associated with the battery itself. If you encounter this problem, contact your mobile PC manufacturer. If you purchased the battery separately from the notebook computer, contact the manufacturer of the battery.

  • Accelerometer turns off when the screen is off

    When testing my application on a Z10 android port the accelerometer turns off when the screen is off. A partial wake lock does not turn the sensor back on. A wake dim screen lock is needed to re - turn on the detector. This behavior forces the screen to be all the time when an application requires the use of these sensors.

    An example would be a pedometer recording the steps throughout the day. In order to operate the screen must be turned on by the application that runs in the background. This will cause a fast draining of the battery and is not an acceptable solution.

    On Android, a partial wake lock is enough to keep the accelerometer running.

    I think this should be reported as a deficiency, a lot of motion carried since Android applications will be blocked by this and my app port is one of them.

    Tested on system Z10, model number STL100-3. Version of the 10.1.0.273 software

    The fix will appear in MR 10.2, 10.2.1 aka.

    I recently submitted a fix for the problem.

  • Two questions. (1) RIP in media player 11 problems. (2) portable speakers do not turn off when the headset is plugged...

    Hey all. I desperately need help. I have a laptop "Durabook" with Windows XP meidand service pack 3 update.  The internal speakers have never turned off when I plug a headset or headphone cable of the adapter into the outlet. It is an option that I have figured out. All my other laptops have silenced the computer speakers when headphones are connected.

    The most frustrating problem I have is in Media Player when you use the tab OUT, when I insert a cd Ripper in the computer, it is not recognized.  If I close and reopen WMP (Windows Media Player) cd, the cover and all the info of the cd is here and ready to be torn APART. Once the cd ends and ejects I insert another cd and nothing happens. Once again, I've closed and reopened WMP and evrything is ready to be torn APART again.

    Please please help.  I can't be the only one who had this problem.  I removed all anti-virus programs, removed and reinstalled WMP, twice.

    I'd appreciate any help.

    Thank you all

  • Satellite Pro A200 (PSAE4E) - power off when the AC adapter is connected

    I bought this laptop for my wife about 2 years, since about 6 months ago, that the laptop was randomly shut off without warning, this only seems to happen while the power supply is connected as well.

    I have read several other posts on other sites with people having similar problems.

    There are various suggested corrections, you must disable the duel core in the bios so that it works only on one heart and he spend dynamic low for fans. I did this about 2 hours ago and touchwood not a single switch off again. This however is not an acceptable solution, there is obviously much more slowly.

    Another suggestion has been updated the bios, I downloaded it now but am very worried to run it, this laptop can stop at any moment, lasting from a few minutes to a few hours. If it stops while updating to bios, I doubt that it would be good news. I don't want to make it work on the single core for the rest of the day/night to see if its stable and then go for it.

    Before that, can I make a call to the toshiba helpline, I read on the forums that this is as well a defect of design within the laptop and there's a reminder of some of the laptops in the Canada, I do not know how it rings true but still a concern to read and might be unacceptable to the owners of the A200.

    Others have advised that it is an overheating problem, it's that I reject, I running SpeedFan and showing a stable 47 temp and it allows to switch off the coast immediately when turned on, yes it could be due to dust build up, something I checked and cleared, it did not a difference for the frequent switch offs.

    Im not too well why it is only when the power supply is connected, I have not tried a different PSU, but those who have had the same problem try this and it has not solved the problem.

    When I unplug my power as well the battery seems last mabye 5 minutes at the most.

    Overall, Im very unhappy all this, toshiba is a brand of 'high' where you expect better quality and pay for it.

    If anyone has any suggestions please let me know, would be also good to hear talk of toshiba support on the issue.

  • Aero off when the external monitor is turned by Nvidia ControlPanel

    Sorry, I forgot to mention my hw: Satellite a100-02 b (geforce go 7600)

    .. and when I reboot Vista behaves a little bit strange.
    a few seconds, everything looks ok, but then it redefines the external monitor to 16-bit color and minimum Vfrequency (60 HZ)
    and a message appears that the 'Desktop Manager' was closed due to a problem.

    Maybe it's because...
    (1) it is an old CRT, not especially known (standard pnp driver)?
    (2) the ability of the graphics card vista is not sufficient in this configuration?

    I heard somewhere that there is a switch in the registry, which disables the dwm.exe test, if the material is
    able to support the aero technologies. What is a way to fix it?

    Hello

    I read about the registry hack that allows the function Aero Vista on graphics cards that are generally not able to manage the Aero feature.
    But I don t think that the modified registry key might help with this problem!

    In any case, I try to understand what you were doing on the laptop
    You have turned on the display on the second external monitor, then you have changed the position of the screen (you turn the display) and you tried to use the Aero on the external monitor.
    Am I wrong?

    Well, what to say, it s not easy to say if she s a problem or just a limitation of Vista Aero.
    I have never tested or used Aero after the display has been set at another position.

    I think you should test Aero on external monitor without rotation.

  • Screen turns off when the Satellite A45-S250 is moved in the direction of less

    Hello.

    I have a satellite A45-S250. I had no previous problem with this machine. However, when the computer is running too long, or it is moved in the slightest way the screen turns off. I don't even have to type very slowly - or I lose the screen.

    But also, as I have said - sometimes I won't even be near the computer and the screen turns off. When I lose the screen if the light shines on it - I can see, it's always VERY fair Sun. Generally, it will come if I use the FN + F5 button.

    I don't know if it is a screen problem or a connection problem. It occurs with increased frequency. Any suggestion would be appreciated.

    Thank you

  • 9.3.4's 6 iOS iPhone Wifi turns off when the phone is locked. How to solve this?

    Hey! I have a 6 - iOS 9.3.4 - 16 GB iPhone. My phone WiFi turns off eventually when I lock it... The problem is that I get no notification because of this problem. I'm too lazy to try troubleshooting for this problem, just read a lot of advice, but it had a bad feedback. How would I fix this? Thank you.

    It is not a problem. This is a design feature which is present in all iPhones and all versions of iOS for 9 years. WiFi turns off 30 seconds after the phone goes to sleep to save battery life. If you want to keep it you must connect the phone to the power.

    Basically, what happens is every time others or so when I plug my T420 in power, the backlight of the screen turns off completely. The screen is always on because if I look close enough I can still see whats on the screen. All the other power lights, Thinklight and other indicators remain on. I can't tell if this is a problem of motherboard, power supply problem or something different, but the problem is very frustrating because I put the computer to sleep and then wake it up back up to continue to use the machine.
