    This is a slightly different model of dv8, but it will work. I guess HP forgot a list for your specific model number. I couldn't find FRO your support in any case page.

  • 4 "other unknown devices" in Device Manager. Windows 7 RTM 64 dv7 1450

    Just bought a computer HP dv7-1450 laptop with AMD Turion X 2 64 processors. Installed Windows 7 RTM 64 and everything seems to work except there are 4 unknown "other devices" listed in Device Manager. The 4 devices are:

    -System base unit (x 3)

    -Unknown Device (x 1)

    I have no idea what are these devices. I tried looking for drivers for chipset on the AMD and HP Web site without result. But I do not know if these are the associated chipsets. One of the devices would be the disk fall sensor hard (it does not appear in the device no matter where Manager)?

    Unfortunately on the HP site, there are not many downloads of drivers available for the 64-bit (Vista). I know that Windows 7 64 drivers won't be available until in October, but if there are not any available Vista drivers either, I expect to see all the drivers for Windows 7?

    The most important thing for me is just to know what are these "other devices" 4 and get the drivers installed.

    Thanks in advance!

  • Satellite M50D - A - 10 L - pilot missing for unknown device

    You just bought a Satellite M50D - A - 10 L and after 1 week, the HARD drive failed. Of course, I had to replace on my spending, because the guarantee would be in about 2 weeks, which was too long to wait for me.
    In any case, I also lost the pre-installed Windows 8.1, but is not a tragedy, because I reinstalled it and everything works well.
    The problem I have I have one of the pilots is not recognized by the "Device Manager". The device is called 'Device ACPI'. Any idea which driver missing is all about?
    Thanks in advance for your answers.

    PS: Do not know how to attach a screenshot of "Device Manager" with missing driver...

    You will probably need to manually install the driver.

    I know that is the one you need, because if you look at the contents of the driver file folder you can see that this driver has support for the hardware ID you have posted.

    [AMDIOV. NTamd64]
    % IOMMU. DeviceDesc%=NULL_DRIVER,PCI\VEN_1002 & DEV_5A23
    % IOMMU. DeviceDesc%=NULL_DRIVER,PCI\VEN_1022 & DEV_1419
    % IOMMU. DeviceDesc%=NULL_DRIVER,PCI\VEN_1022 & DEV_1577
    % IOMMU. DeviceDesc%=NULL_DRIVER,PCI\VEN_1022 & DEV_1423
    % IOMMU. DeviceDesc%=NULL_DRIVER,PCI\VEN_1022 & DEV_1437
    % IOMMU. DeviceDesc%=NULL_DRIVER,PCI\VEN_1022 & DEV_1449
    % IOMMU. DeviceDesc%=NULL_DRIVER,PCI\VEN_1022 & DEV_1611

    Sometimes the automatic installer does not install the driver, so you must outwit the PC.

    Go to Device Manager and click on the device IOMMU requiring the driver.

    Click the driver tab.  Click on set to update driver.

    Select her browse my computer for driver software option and navigate to the folder of the driver that was created when you ran the file.

    This file will be located in C:\SWSetup\sp67924.

    Make sure that the include subfolders is selected and the driver should install.

    Restart the PC.

    ACPI defines hardware and software interfaces that allow focus on the OS configuration and power management to enumerate and configure motherboard devices.
    For example: ACPI is necessary for the standby and hibernation mode.

    Now your question; the new BIOS has been updated and configured to using VISTA.
    It seems that VISTA was not compatible with the previous version of BIOS because the ACPI interface. Now you can install Vista on the laptop, but it seems that you need a driver. Possibly new chipset driver version might help. But as you probably know, the drivers are not available at this time. Unfortunately

    Hi ymkx,

    All the drivers and tools that you need can be downloaded here:
    http://EU.computers.Toshiba-Europe.com > support & downloads > download drivers

    Also this nice article should help you identify the devices:

    Additionally, make sure that Service Pack 3 is installed before starting with the installation of the driver.

  • Unknown devices in device Windows 7 Manager - dv7-2170us

    I have a laptop dv7-2170us.

    I did a clean install with Windows 7 Home Premium 64-bit.

    I used the drivers for this model of laptop on HP's site.

    I get a few unknown devices in Device Manager.

    I tried to uninstall the device and re - install to allow Windows to re - detect but no drivers are found.  See the pictures below, what devices could they maybe refer to?

    I have all the necessary drivers load that I know and I installed a driver who looked valid on the site of HP drivers.

    EDIT: Everything works!  Thanks for the tip of Daniel.  I googled how to identify the ID of material and is here with this site http://www.pcidatabase.com/ , punch in the device id and bam, it IS the card reader.  Weird because it worked perfectly.  But I downloaded the driver even re-installed and this solved the problem.


    I tried the Intel Chipset utility, did not work. However, here is the hardware id:

    If you look closely, you will notice that each of these devices are in fact different.

  • Satellite L300 PSLBGE - unknown device in Device Manager


    I would be very grateful for any help/tips if anyone has an idea what to do...

    My friend has the laptop mentioned above (w/o OS preinstalled) and we can't get the graphics card work properly - situation is the following

    (1) mobile intel 4 series express chipset family, and an unknown device with an exclamation mark in Device Manager
    (2) both are on the same PCI BUS 0, device 2?
    (3) intel does not work because there is no free resources (I should remove the unknown device?) to work with
    (4) HW ID for the unknown device is pci ven_8086 & dev_2A43 and intel pci ven_8086 & dev_2A42 (so basically the same, right?)
    (5) Finally, and most importantly, if I go to the desktop-customize-advanced (first of all no resolution 1280 * 800) I see under adapter type:. Exactly, nothing... under properties, it appears: device not plug and play, Super VGA and under driver, I see just the status and the ability to stop, off, automatic, ask... the device at startup... If I turn it off, the screen just does not shine when the laptop is turned on...
    Any ideas? I'm insaneeeeee...

    Vista Home Premium, all other Toshiba SW installed (value pack, intel BIOS 1.9, etc. - maybe the BIOS did it?)

    Thanks in advance!

    PS maybe SP1 I now install help?


    Wait a minute: I checked the Vendor ID and Device ID on www.pcidatabase.com and this is the graphics card Intel. So I think that's the reason why you can t change the resolution of the screen.

    I guess you forgot to install the display driver. See the Web from Toshiba site because here you can download the driver:
    http://EU.computers.Toshiba-Europe.com-online decision-making supported Downloads & => Download drivers

    After that you should t have no exclamation point.

    You can install SP1 for Vista, but that does not solve the problem with the missing display driver. But you should install it because it contains a lot of updates to security, they are important. In addition, I recommend to install SP2 for Vista.

    Good bye
