Bluetooth does not work since installing Vista SP2

I have a HP Pavilion dv6 1128tx laptop.  It has bluetooth built-in and used to connect to my phone without problem.  I recently upgraded to Vista SP2, and since then, bluetooth does not work.  In the control panel when I click on bluetooth devices it does not connect, and when I click on bluetooth, nothing happens.  I downloaded the latest drivers from HP, I installed it is said in the end the process there is no bluetooth device installed and the only option is to cancel the installation.  I've been on microsoft site http://support.microsoft.com/kb/960531/ where I used the option "fix it for me", which has removed the option of Control Panel devices and I don't know how to fix this!  I followed the instructions from HP on this page http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&dlc=en&cc=au&product=3938840&docname=c00915262, but I don't see anything on bluetooth technology on the Device Manager page.

Any thoughts? !  Ta!

HELO JosieC, welcome.

In Device Manager, there are all the devices with a yellow mark ! next to them? Is there an 'unknown' devices listed?

You could try the system restore to restore the computer prior to the installation of SP2.

1. click on START
2. Type "System Restore" (without the quotes) and press enter
3 follow the prompts to restore your system to a date BEFORE the problem started

Let us know what happens

  • Laptop does not start after installing vista sp2

    My Dell XPS 1530 stopped working after installing vista sp2. He gave me instructions for installation, step 1 of 3 and it went all that they way up to step 3 of 3 and said its closure and never came back...
    Please let me know, how to start the laptop.

    Hello GoogleGuru,
    Thank you for visiting the Microsoft Answers forum.
    Because your computer does not start until the desktop computer, we were able to try the system restore to a point before you install SP2.
    Thus, with the computer is shut down. Press the power button, then press on and press F8 until you see the startup options, and then it will give you the ability to boot to the last known good configuration. (select it).

    If this does not work, you can try to boot from the Vista DVD and use the recovery console to perform a restore of the system to another point in time.

    Post back with the results.

    Any help appreceated

    Bill

    Train from my own experience the SP1 is not fully compatible with the various drivers.
    In case you looks that the audio driver does not work with SP1.

    Don t know what sound card you have (maybe Realtek?), but a sound card driver update would be desirable.
    If it doesn t help you will need to wait until it comes out an update of the audio driver

    Vista and Windows 7 updated drivers love then here's how update the most important.

    This is my generic how updates of appropriate driver:

    This utility, it is easy see which versions are loaded:

    -Free - DriverView utility displays the list of all device drivers currently loaded on your system.
    For each driver in the list, additional useful information is displayed: load address of the driver,
    Description, version, product name, company that created the driver and more.
    http://www.NirSoft.NET/utils/DriverView.html

    For drivers, visit manufacturer of emergency system and of the manufacturer of the device that are the most common.
    Control Panel - device - Graphics Manager - note the brand and complete model
    your video card - double - tab of the driver - write version information. Now, click on update
    Driver (this can do nothing as MS is far behind the certification of drivers) - then right-click.
    Uninstall - REBOOT it will refresh the driver stack.

    Repeat this for network - card (NIC), Wifi network, sound, mouse, and keyboard if 3rd party
    with their own software and drivers and all other main drivers that you have.

    Now in the system manufacturer (Dell, HP, Toshiba as examples) site (in a restaurant), peripheral
    Site of the manufacturer (Realtek, Intel, Nvidia, ATI, for example) and get their latest versions. (Look for
    BIOS, Chipset and software updates on the site of the manufacturer of the system here.)

    Download - SAVE - go to where you put them - right click - RUN AD ADMIN - REBOOT after
    each installation.

    Always check in the Device Manager - drivers tab to be sure the version you actually install
    presents itself. This is because some restore drivers before the most recent is installed (sound card drivers
    in particular that) so to install a driver - reboot - check that it is installed and repeat as
    necessary.

    Repeat to the manufacturers - BTW in the DO NOT RUN THEIR SCANNER device - check
    manually by model.

    Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

    How to install a device driver in Vista Device Manager

    If you update the drivers manually, then it's a good idea to disable the facilities of driver under Windows
    Updates, that leaves about Windows updates but it will not install the drivers that will be generally
    older and cause problems. If updates offers a new driver and then HIDE it (right click on it), then
    get new manually if you wish.

  • Flash player 10 does not work on windows vista sp2, any NPSWF files found in the system as well

    Hi, I use windows vista, downloaded flash player 10 several times but it will never work.

    just updated to SP2 today after reading the other popular solution here, but it still will not work.

    I use IE 8, went to C:/windows/system32/c:\windows\system32\macromed/flash on my computer but it

    is not NPSWF files at all.

    There are those I have flash10e.ocx install.log, flashUtil10e.exe, uninstall_activeX.exe

    and trust flashplayer with rpconverter.ctg in her file.

    Please help me with this, thanks a lot!

    Hi candy, happy you found that Shockwave Flash Object, it works with Flash files and is very important

    NPSWF files you said aren't there, those who are for the browser Firefox or Chrome or any other browser. If you use Firefox and you want the Flash Player to do this, close all your browsers if you are looking only at your office.

    Click on the Flash Player for Firefox installer and save it on your desktop. Then run it from your desktop, and after it is finished installing, restart your computer.

    Then using Firefox go to the plug-ins and find a SWF vs 10.0.45.2 and make sure that this option is enabled. It's like the Shockwave Flash for Internet Explorer object, but it is one that works with Firefox.

    I would like to know if this is what you wanted to do. If you do not use Firefox, but Chrome or any other browser, this will work for that one also.

    If you do not use another browser, then do this. I have just thot maybe that you did and that is why you were concerned that the NPSWF files were not there.

    Thank you
