Hello

Try to use Recovery Manager to reinstall your original graphics driver (if your laptop uses Nvidia optimus, reinstall the Intel gpu driver) - how to use the Recovery Manager to reinstall the drivers and software is detailed in the document at the link below.

Recovery Manager - Windows 8.

After reinstalling, restart the laptop.

  • Cannot adjust the brightness after display driver update on Satellite L855-118

    Hello.

    I just bought a SATELLITE L855-118, with ATI graphics card today, it was between this and another of them, but I know that you have problems updating graphics drivers on a portable Sony.

    I did a restore point.

    So I uninstalled the ATI catalyst graphics card and then did a sweeper driver and rebooted and then installed catalyst 12.6, installed fine, but my screen went to the maximum brightness and I can't adjust, BRIGHTNESS osd is displayed but the brightness of the screen does not change.

    So I used my restore point.

    This time I crushed the catalyst 8.9 with 12.6 stock, still cannot adjust the brightness.

    Someone knows how to solve this problem.

    Hello:

    Yes that's fine.

    Here are the graphics drivers that you need for the W10...

    This package provides the graphics driver AMD/Intel switchable high definition (HD) for models of laptop computers that are running an operating system supported. For laptops equipped with switchable graphics modes, this package contains the drivers for the two graphics (GPU). Switchable graphics allow users to switch between a mode of graphics to save energy (normally used under the power of the battery) and a high-performance graphics mode.

  • Cannot run the screen saver because it requires a newer video card or one that is compataible with Direct3D.

    Hello

    I recently rebooted my computer; (Packard Bell) and now cannot run games or screen savers because it does not start. I think my problem has something to do with a Direct3D card? When I run screensavers, I get this message:
    Cannot run the screen saver because it requires a newer video card or one that is compataible with Direct3D.
    I have the impression that sound when I run the 3D games, such as minecraft or GMOD.
    I run on Windows Vista Edition Home Premium and does not do anything but re - install my computer because it wouldn't start.
    It is not as if the graphics card is not there, so I'm really confused!

    Hello

    Your language is good enough, don't be sorry

    Your Support page is not a listed Intel graphic driver. Your laptop came with 64-bit Windows 8 & I guess you clean installed Windows 7 64 bit, right?

    Your laptop has Intel/NVIDIA switchable graphics system. In this case, you can install the Intel graphics driver first & then NVIDIA driver HP supports the page. for example,.

    You can try this graphics driver Intel Intel directly. Download, save & install it. Restart the system.

    Then download, save & install the NVIDIA graphics driver. Reboot the system after installation of finishing.

    Check whether the problem is resolved.

  • HP Pavilion Dv6 Notebook PC: Cannot adjust the brightness/contrast

    Hi all

    After a new installation of Windows 7 64 bit Home Premium on my HP Pavilion dv6, I find that I can't adjust the brightness/contrast of the screen. Initially, I had installed a generic pnp Monitor driver, but after reading a solution which recommends to uninstall, I did, but to no avail. I have also tried installing HP Support Assistant, scanned my laptop computer for outdated drivers and have installed the recommended drivers, but I am always faced with the same problem.

    If you provide me with any details on my laptop, let me know.

    Thank you.

    Hello.

    I realized later that I had 215 updates of windows install. After I did, the problem solved itself, but I think that among the updates has been one for the graphics driver.

    Hello:

    There are two Intel driver links to the choices on your laptop support page.

    I explored the folder of the driver of this driver file to support your laptop and driver page, and it is suitable to use 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.

    File name: sp69589.exe

    The hardware ID for the Intel graphics card in your laptop must be one of these...

    ;=====================================================================
    ;    Windows 8.1 install
    ;=====================================================================
    [IntelGfx.NTamd64.6.3]

    % iVLVGMT0% = iVLV2M_w81, PCI VEN_8086 & DEV_0F31 & SUBSYS_220F103C
    % iVLVGMT0% = iVLV2M_w81, PCI VEN_8086 & DEV_0F31 & SUBSYS_2213103C

    You should see a device from Intel HD graphics instead of the graphics card base of Microsoft, and unless you can get the graphics driver to install you will not be able to adjust the brightness of the screen.

    Is the above driver do not install the Intel graphics card automatically, try to install the driver manually by navigating to the folder of the driver that is created after running the above file.

    Confirm that the hardware for the Intel graphics card ID matches one of the above since the driver installation information file that I posted.

    To find the ID of the hardware, Device Manager, click the graphics card Microsoft Basic.

    Then click on the Details tab in the upper part of the window Microsoft Basic graphics card.

    Now you should see a drop-down list of property and it is set by default to the Description of the unit.

    On this list and select the 3rd point (Hardware ID).

    Confirm that the hardware ID, you see there is one of those listed that I posted.

    Yes, that's the correct stuff. The Kingston can operate at 1.35 or 1.5 volt. Before the upgrade, although I advise you, you remove the RAM that is in it and watch it. Is - this 4 black memory per side or 8? Match what you have.

  • Cannot adjust the brightness of the screen after the new installation of Windows 7

    I have a Pavilion dv2945se notebook. I have completely updated the Nvidia geforce 7150 m drivers. My laptop came with Windows Vista Home Premium 64-bit, and I did a new install of Windows 7 Home Premium 64-bit. I can't adjust the brightness of the display. I narrowed down the problem to the generic PnP Monitor driver. How can I solve this problem?

    Edit: I mean "impossible to adjust the brightness of the display" that every time I go into power options and trying to use the cursor, Windows Explorer crashes. Also, my fn + F7 and F8 keys light work before I connect to windows, but not after. I think that something will charge when I connect to windows that is causing the problem. So I went in Mode safe, but then all that allows to control the brightness has not loaded when I went into safe mode, which was not helpful. I also went into MSConfig and disabled all startup programs, but again, I have the same problem. The brightness of the keys work before connect you to Windows, but not thereafter.

    When I turn off the device generic PnP monitor (1) can't adjust the brightness at all and (2) the Power Options window stops freezing. That's how I've narrowed the problem to the generic PnP Monitor driver.

    I finally solved this by uninstalling the driver for the ALPS touchpad. Because there are no Windows 7 drivers for my laptop even though it is listed in the models capable of upgrading to Windows 7, I used Windows Vista touchpad drivers. It was the cause of my problem with brightness adjustment. I don't know why it worked, but I've narrowed it down by disabling all processes start and then from their one at a time to see what caused the problem. As soon as I started Apoint.exe, I started to have problems.

    Now, I just have to find a way to disable the touchpad tapping without the ALPS drivers.
