webcam HP envy problem

I have a laptop HP Envy with windows 8 is installed, and for some reason, the laptop is unable to find or use the webcam which is already there. HP Truevision HD. When I opened the window of properties of this device I get this message: currently, this hardware device is not connected to the computer. (Code 45). To resolve this problem, reconnect this hardware device to the computer. Exactly how am I supposed to do if the webcam is in the laptop internally? Thank you.

Most often when a device does not work, it is because the driver is damaged.  Re-install a new copy should help

  • How can I activate my HP TrueVision webcam (HP Envy dv7;) Windows 8)

    Really, I'm losing my patience here. My laptop is brand new. I remember the first time I started it, I clicked on CyberLink YouCam and the machine worked. I even took a picture with her.

    Since then, I try to activate the webcam and it doesn't work. I wanted to video chat on Skype but the webcam was not enabled, there is no choice of webcam.

    I've read that if you go on Facebook and click 'Change your profile picture' and then 'take a picture' it activates the webcam, but not in my case.

    When I run CyberLink YouCam, it says that he has not found webcam and if I activate it if I a.

    So here's my question: how to turn on the webcam? Please, give me the instructions on how it works. What I have to press the key combination or whatever.

    I'm the HP dv7-7202eg with Windows 8. Bought and used in Austria, if that information makes a difference :-)

    If the webcam was working before, it may be "stuck".  If this is the case, then a reset can throw everything is free and you'll be "back in business" in a few minutes.  If the reset does not fix it, there are a few more options.  Stop when it works.

    Downstairs is a Help Guide that goes over the tests and the options you have available on the software to help you solve the problem.

    This is a whole new system. If all else fails, please do call HP and ask for help!  Just because the webcam worked before doesn't mean it works now.  These webcams little are fragile and they can break - the wires are tiny and they can be crushed, twisted or broken at any time.  If the tenacious webcam does not work, call HP and ask for help.  Something may have been missed or nit can be broken!

    Hi there @RandomProbllama,

    Welcome to the Forums of HP Support!  It's a good place to find the help you need, other users, HP experts and other support staff.  I understand that the audio does not work on your computer after you reformat.  I'm happy to help you with this.

    Looking at the page "Download drivers and software" HP ENVY 23 - d000el TouchSmart all-in-One desktop PC , I see that there are no specific drivers available for Windows 10.

    Why did you reformat the system?

    What method did you use to install Windows 10?

    If you check in Device Manager, which appears in your sound devices?

    Have you tried to remove any audio device and then searching for the hardware changes?

    Please let me know.

  • Solution for Webcam sleep & back problems after the upgrade to Windows 7

    Just thought I'd share the solution I recently found a problem I've had since a Satellite Pro A200 GE 26 Q of the upgrade from Vista to Windows 7.

    I installed the software webcam for windows 7 on the toshiba site and built-in Chicony camera would work very well after a reboot, but if the computer is in sleep for a long enough period, the unit would stay asleep when the computer woke up and wouldn't work at all, unless the computer has fully restarted.

    The solution lies in a change in the registry to force the computer to update the webcam USB controller is attached, after the release of sleep. It was apparently the default for Vista when it was released, but was changed in Vista SP1 and Windows 7. Designed for Vista original material which did not have its drivers/registry updated entries could therefore be subject to a failure because of changes to the default settings through the updates of windows. Toshiba, it seems, do not think that this issue then of the extinction of the registry fix for Win7 upgrades for the satellite Pro A200. Therefore fix manually.

    The article where the solution is here: [http://support.microsoft.com/kb/928631]

    You do NOT have the file of the fix, you must only make the change to the registry described later.

    You need turn on the camera while you do the following to make sure that it appears in Device Manager correctly.

    Step 1: Determine the specific USB host controller


    # Click on * early *, enter devmgmt.msc #the * search * box, then click on * devmgmt.msc* in the * list of programs.
    # The * view * menu, click on * devices of * connection *.
    # Expand the processor node. For example, expand * ACPI * Multiprocessor PC *. (In my case, * ACPI x 86 based PC) *.
    # Extend * system compatible ACPI Microsoft *.
    # Extend * PCI Bus *. Several USB host controllers will be listed.
    # Expand each USB host controller node, and then expand successive subnodes until you find the name of the device that is failing. For example, the device entry might look like the following: ACPI Multiprocessor PC\Microsoft ACPI-Compliant System\PCI Bus\Intel (R) \ICH8 family USB Universal Host Controller - drive root Hub\fingerprint 2830\USB * (Note: for me, I found the webcam to ACPI x 86 PC\Microsoft ACPI-Compliant System\PCI Bus\Intel (R) \ICH8 family USB2 Enhanced Host Controller - 283A\USB Root Hub + USB Composite Device\Chicony USB 2.0 Camera-based) *.
    # When you have located the device, right click on the associated and then USB host controller click on * properties *. In the example that is listed in step 6 you would right-click * Intel(r) ICH8 Family USB Universal Host Controller-* 2830, then click on * properties *. (* Again, for me it was different - ICH8 Family USB2 Enhanced Host Controller - 283 a *).
    # Click on the * details * tab.
    # Select * pilot key * in the list. The driver key will look like the following. Note the last four digits of this driver key. {36fc9e60-c465-11cf-8056-444553540000} \0002 * (on my system it's: (36fc9e60-c465-11cf-8056-444553540000) \0005*).

    Step 2: Add the ForceHCResetOnResume registry value for the USB host controller


    # Click on * early *, type regedit #in the * search * box, then click on * regedit.exe* in the * list of programs.
    # Find and then click the registry subkeys that are similar to the following: * HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contr ol\Class{36FC9E60-C465-11CF-8056-444553540000}\Four-digit_number.* in this step, the numero_a_quatre_chiffres is a placeholder for the USB devices in the system.
    # You must search the registry subkey by using the value that you noted in step 9 above. For example, if the key of the pilot to step 9 is * {36fc9e60-c465-11cf-8056-444553540000} \0002*, then you need to get * HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contr ol\Class {36FC9E60-C465-11CF-8056-444553540000} \0002. (For me, as mentioned above, this was \0005 (36fc9e60-c465-11cf-8056-444553540000)). *

    # On the * Edit * menu, point on * New * and then click on * DWORD value *.
    # Type# * ForceHCResetOnResume * to the name of the DWORD and then press ENTER.
    # Right click * ForceHCResetOnResume * and then click on * edit *.
    # In the * boite box the value data, type# 1 and then click on * OK *.
    # Exit the registry editor.
    # Restart the computer.

    This fixed the problem for a long time for me. I'm writing this in case it helps someone else who has the same problem. If anyone from Toshiba never reads this, you might consider adding the registry fixes for upgrades of windows 7 on the download page for this & all other models affected.

    Big Hey what s announced and detailed, thank you! :)
    I m wondering how you discovered it.

    But I want to add something: before you make or change something in the Windows registry, make a backup of it. In the worst cases, restore you the old Windows registry. Just to be sure ;)

  • 13 d-0016nl envy: problems with the HDMI audio

    Dear Sirs,

    Due to some problems with an engineering program I had to reinstall Windows 10 on my laptop. The version of Windows is the same of the one installed on the laptop when I bought it. Before the laptop with HDMI audio installation worked fine, but then, while the HDMI video continues to work well, the audio turns off directly from the laptop, such that the cable was not connected.

    I tried to activate the 'reproduction devices' HDMI connection, but I'm not able to do this because it's as if the cable is not connected, and the HDMI connection icon appears as gray.

    I tried to update the audio driver, but it didn't work, so I tried to download and install the latest version of these drivers from the hp site but neither this worked.

    Can you help me? The laptop is quite new and I would like to solve this problem without using 2 different cables to connect also a speaker with a cable to the because the HDMI does not work as it should.

    Thanks in advance,

    Martina.

    You are the very welcome, Martina.

    It would be the graphics driver you need install the HDMI audio driver...

    This package provides the driver that allows graphics Intel high definition (HD) in the notebook models that are running an operating system supported. If the video output high-definition multimedia interface (HDMI) is supported, this package also installs the HDMI Audio Driver.

    Hello

    I have a problem with my Broadcom BCM43142 802.11 bgn adapter Wi - Fi because I upgraded my windows 8 to 10

    wifi works fine but then after a while a get on the wifi icon's yellow warning triangle, no internet, reviews
    I have to disable and then enable the adapter to operate again, the same problem, but after a while again accurs

    card driver is updated to the latest version 7.35.275.2, the driver date 02/07/2015 via the HP support assistant

    It says no new updates

    Help, please

    Thank you

    Hi @HadjadjTaha,

    Thank you for your inquiry.

    I understand that since the upgrade of Windows 8 for Windows 10 your Wi - Fi works fine, but after awhile the icon won't say no Internet and you will need to disable and re-enable the adapter to regain access to the Internet.

    Would check you this setting.

    • Go to the Device Manager
    • Click the network card to expand the list
    • Right-click on the adapter that is listed and choose Properties
    • Click the power management tab
    • If "allow the computer to turn off this device to save power" is ticked, please remove it.
    • Click OK
    • Repeat the process above listed all types of adapters.

    Here is a link to PC HP - troubleshooting wireless network and Internet (10 windows) that can also help.

    Please let me know the results.

  • Satellite A200 - 13 M - XP x 64 - problems with the modem drivers and webcam

    Hello!
    I recently installed Windows XP x 64 on my laptop.
    I have two devices that do not work properly.

    (1) does anyone know how to get the driver for the built-in modem? There is no version the x 64 required for download.

    (2) the webcam does not work. I had a problem of 'Windows Image Acquisition': error telling me to put this service to activate the webcam. The problem is that this service is, by default, already activated.

    Thank you for your help.

    Hello

    You are right. 64-bit drivers are not available. Unfortunately, 64-bit version is not supported. To be honest, I'm sure that the modem is not so important for you and you can turn off this feature.

    I can't say much because I use the 32-bit operating system only on webcam.
