My laptop thinks that he is in dual screen mode.

Last night I tried to connect my Dell XPS 17 laptop to my TV via the HDMI port and I would get "No signal" on tv as if she didn't even know that the HDMI cable is connected. I failed her and finally found that there was no sign of my Nvidia graphics card in Device Manager (I had problems before graphics card.) All I had to do was update the driver and the new software has been installed and both monitors worked well.

Since then, after I disconnected my TV, my laptop randomly enters a dual mode screen in which "projector only" must be engaged because my screen goes black but I still audio. Need me 5 minutes to continuously hit Fn + F1 to switch screens where I can hit the windows key + p and return to the screen only. It seems that the times, he jumps in to start, restart, or after hibernation. He also did this when trying to play a powerpoint that would usually play right on the screen of my laptop without problem.

Any Suggestions?

  • Laptop turns on in the bag... I think that updating Windows?

    I just had the unpleasant surprise of out my laptop bag after 2 hours and it was still running! It was hot to the touch and with gratitude, it seems to work very well. But it's the third time, it's happened since I bought it in January and it is quite relative. I put the computer to sleep and most of the time that he died, but I think that when windows tries to install the updates, it will not really sleep. So, I'm in the following with a hot laptop location. I really don't want to damage this machine, if any suggestions how I can make sure it is really wrong to sleep when I said to, Windows Update or not, would be great.

    Thank you!

    Windows should install no updates while you sleep on the battery, but I would check your settings to ensure that it was still defined in this way.

    If you need to know, you can find what's causing your computer to wake up.  Just do this:

    1. Click the Start button, select Prompt Admin.
    2. Type powercfg /lastwake and he will tell you what program or device caused the alarm.

  • Satellite Pro P100: I think that my graphics card is defective

    I have a satellite Pro P100 with a GeForce Go 7600 and think that graphic design is faulty. I was playing a game that has good graphics and I was testing the FPS cause it was laggy.

    On average, that a decent graphics card must be able to give an SPF of 20-29 but my geforce go overlooked 9-13, but I have a Satellite M60-164 before this laptop with a Mobility Radeon X 1700 graphics card and he played much better give me the range good fps. But maybe the Geforce could well be a bad card in general.

    Is it possible to update the graphics in the P100? He says dedicated graphics card.

    Hello

    first of all, no can´t you don't share your graphics card because the card is "wired" on the circuit board. With dedicated was he has it s own graphic memory and does not have a main RAM memory to use as graphics memory.

    Regarding your performance:
    Would be interesting what operating system you are using. In the case of Vista, I understand why performance is not good, because vista requires so many resources that the rest of the apps/games would not get the necessary resources for the successful REALLY.
    If you have Windows XP, then update your drivers, but use drivers on sites like:

    http://www.laptopvideo2go.com/ (2 GB LaptopVideo & NVIDIA Related News)
    http://www.OmegaDrivers.NET/ (OmegaDrivers.net - home of the Omega Drivers for desktop/laptop ATI & NVIDIA cards)

    because these drivers are almost on mobile systems, and they use the most versions of real driver of ATI and Nvidia.

    Just try it and give some feedback.

  • Satellite A100-454: I think that the sound is low

    I think that the general volume of the A100-454 is too low, any suggestions? Is this a driver problem or I have to config something?

    Thank you.

    Hello

    This may not be a driver problem audio because if the sound see sound card device has been recognized, and the audio driver has been properly installed.
    Vista is installed on this laptop?

    In the control panel in the sound options, you will find various sound controls.
    You should check if all controls are set to the next level

    If everything is set max I guess that the sound has been set up. possible level.
    In this case it is not things to do

  • Lenovo E440 microphones reversed? I think that the left and right are wrong

    Hi, I have E440 i5 8 GB Windows 10 to date and version of driver Conexant 20751 SmartAudio HD 8.66.16.50. I clicked on "update driver" and came to is that it is the most recent version.

    In the settings of the card, I enabled 'hear this device' and position normal when you look at the screen and your hands on the keyboard, if you type the right hole mic I can hear the left audio channel and vice versa for the left. Is this normal? Try with your laptop. I mean, it would be nice if you want to record something with the laptop back on what you want to record, but I think that most of the people in the land would the laptop screen making in the face of what they want to record, especially if they're going to use the camera and video.

    Looked at google but nothing came

    Add: I noticed in the properties: configuration of the Microphone, in the 'Options' tab advanced, there in the background 'Improve the Signal' and a checkbox "Enable sound improvements" WHICH I ALWAYS turn OFF and the sound quality is crisp, clear and loud, but the pickups are reversed, now if I select this check box, the sound is really bad miserable, for 256 Kbps 32 Kbps and its going to MONO. Any permeable I scratch, sound comes from the Center, so I would REALLY like that this "activate sound improvements" disabled people, hands down. PD: This option is not even reduce any type of noise, I know it's what he is for, I can still hear my strikes and miners of sounds equally with it enab/disab.

    Another thing is: it not "Conexant Audio Setup GUI" nowhere to be seen, I have looked everywhere in the PC, this audio driver just doesn't does not with any audio different installation "Dolby" read and option on the 'enable strengthening its' in the record.

    OK, updated, I thought I had won the battle, well, almost, rebooted again and reinstalled my pc the * beep * driver CONEXANT, but found another solution, followed this tutorial
    https://blogs.msdn.Microsoft.com/matthew_van_eerde/2010/08/23/troubleshooting-how-to-install-the-MIC...
    And recovered the "pilot High Definition" and I think that this time it will stay.
    One thing I noticed that the volume icon in the lower right missing, check list "hide icons" and "Volume", it turned on, I am appearing at this time, may try another reboot.

  • How to reset the default monitor on Acer 2920, computer laptop think always connected to an external monitor

    Hello, I hope you can help me! I have a laptop Aspire 2920 with Windows Vista Home Edition O.S. It starts and works fine except that after I used it with an external monitor (a tv screen) on the possibility of using the external monitor, it only now starting to think that the monitor is the flat screen tv and doesn't recognize the normal screen of the laptop. The laptop screen is now "pixeled" and shows only like 2/3 of its total width. I checked in Control Panel and it has recorded as the 'normal' monitor flat screen, but I can't way a find to tell the computer that the monitor is the same as usual and not the flat screen tv. Thank you!!!

    Dear Lawrence,

    I ve solved the problem.

    Do you have your suggestion to reset and did not work, but keeping your idea, I hooked to an external monitor, mounted in Control Panel, remove the "non-existent" monitor in the device section.

    At this point, I had no image at all in the laptop and only the external monitor.

    Turn off the computer and then reset the power supply.

    Because the computer did not all other monitors, he then had to use the one by default with the default resolution, etc..

    Thanks, it was a great help!

  • Last night, my laptop that runs windows xp blue screened and says something about the queue

    original title: help solve a mistake, please on windows xp

    Last night my laptop that runs windows xp blue screened and says something about the queue and to bring the computer out of which I did. I just tried to turn it on an hour ago, I use it now, and I got a message saying he had recovered from a serious error and I wanted to report to microsoft? I clicked Yes, but unbeknownst to me, I had no internet connection at the point of having to re-enter my our Verizon router WEP number in this laptop. I essentially self-taught myself much on computers that tell you, I'm not really computer literate, but if you can point me in the right direction, I can very well do. This is where to ask my question/problem. I went in the event viewer and found this error/explanation: Index information is corrupt and Indexing Service cannot re - index the content automatically. User action: stop and restart the indexing service using the following command:

    SC stop cisvc

    SC start cisvc

    Can someone tell me please how to do this?  I think I know, but I'm really not sure so please help... Thank you

    It really seems to me as if you had a temporary problem which has now disappeared and that you probably do not need to do anything.

    However, please click Start, and then click Printers and faxes and report what, if anything, you see in the window that opens.

    If you don't see an icon for the printer that you think should be there, you need to fix this.  On the other hand, if your printer icon is there - or if you do not have a printer attached to your computer - you need not do anything.

    If you want your computer to be a little faster and at the same time save space on your hard drive, read the LifeHacker article I linked in my previous post.  However, you need not to do, and you can erase [probably] regardless of the index corruption has occurred by starting and stopping the Indexing Service (cisvc) by entering commands in a command prompt window that I described.

    Yet once, you don't need to change your encryption WEP to WPA or WPA2 wifi, but doing so will make your network more secure wireless.  If you want to change your encryption, you would start by changing the configuration of your router from Verizon.  You should be able to find detailed instructions on the Verizon support site.  I don't know if you have Verizon FiOS or Verizon DSL service; This is a page of relevant support FiOS--> http://www22.verizon.com/ResidentialHelp/FiOSInternet/Networking/Setup/Security/124980.htm

  • EliteBook 8740w thinks that the lid is closed, but it is open?

    Hello

    I have an EliteBook 8740w running Windows 7 64 bit and I have a strange problem where the laptop seems to think that the cover is closed when it is open.

    If the cover is open, the screen is off the touchpad and keyboard, the two do not work and not the function of the buttons volume or wifi. When the screen is almost completely closed the screen turns back on, the keyboard and the mouse are beginning to work again, but it is not usable, because it is about 5 degrees, far from fully closed.

    It seems that it is just reverse how it is supposed to work?

    All this happened when I unplugged my power cord. The screen turned white and it has been in place since then. I tried several reboots, nothing seems to recover.

    I can run on my external monitor very well, so the laptop seems to be otherwise functional

    Thanks in advance for any ideas

    Maybe you did not reset properly.

    Remove the battery and adapter and all the things connected to the laptop.

    Hold the power button down for 1 full minute and only plug the adapter back to (do not insert the battery) and start.

    The next time you stop everything, install the battery.

    Could someone please recommend some course HP laptop model that can be used the same hard drive as G62-355DX use?

    Even the hard drive can not put it in the bag laptop, but work with the HARD drive interface.

    Thank you in advance.

    Hello! You need a new PC Yep!
    But there are other ways to do

    You can buy a SATA USB adapter that will allow you to plug in the HARD drive on another PC and the take-off data

  • As an administrator, but he doesn't think that I'm? -Windows 7 Home Premium

    Hey guys,.

    I use Windows 7 Home Premium on an HP laptop.

    In response to a previous question, I tried to run a SFC (System File Checker) scan using the command prompt (sfc/scannow).  He told me:
    You must be an administrator running a console session in order to use the sfc utility.

    But I am the administrator.
    going to start / Control Panel / user accounts and parental controls / user accounts... I am clear as an administrator.

    But I'm not.  I think that's why my Shut Down buttons disappeared (it was the previous question, I mentioned).  I can no longer stop, restart or sleep.  My only option is to disconnect.
    It started about 2 weeks after 10 months of work very well.

    NOTE USEFUL? :
    I have 2 computers running on the same internet connection.  The other is a desktop under Windows XP Home Edition.  This office does not use of wireless to connect, but my laptop doesn't.
    I think THAT this can happen when I turned off wi - fi and had two computers connected with hardline via the router.

    Also note: I have Win7 Home, so I can't right-click on command prompt in the Start Menu (I can, but it does nothing) and have therefore no possibility to choose 'run as administrator '.

    I really want just my close down/restart back buttons on my laptop.  This is the question at first.
    Help, please?

    Thank you.

    Thanks for the comments. I guess that's the price we pay for Windows is an open system. Every Tom, Dick and Harry can write an application with little regard to how he might divert the normal operation of Windows. The advantage of an open system is, of course, the considerable variation in the applications we receive.
