Pavilion dv7 - no wireless or bluetooth after power surge?

Hi all

I'm trying to diagnose a failure on a Pavilion dv7-4130sa running Windows 7.

The WiFi was working fine until yesterday afternoon when I think he cut a power surge or a very brief power. It was not enough to reset clocks or turn off the TV, cable box, etc, but I had to reset the wireless router.

Central heating also stopped working, due to a fuse and the defective pump - but maybe it's just a coincidence.

Now, the wireless in the system tray icon shows a red cross with Windows indicating an error message...

Windows cannot load the driver for this hardware device. The driver may be corrupted or missing.

I know this isn't the router as my phone and netbook both work more wireless. I was thinking of doing a system restore, but I was wondering that if bluetooth and wireless cards are defective, this does not solve the problem.

Any help or advice would be much appreciated.

  • Pavilion DV7-1451nr: Wireless button stays amber

    My pavilion dv7-1451nr turns wireless keyboard blue when I have to reset the motherboard by removing the battery and press the power button / stop seconds, after which I plug in charger to him while leaving the battery and press the power button / stop. After that, I would like to press f10 to enter the bios setup, then I would like to load the defaults, save and exit.

    After doing all that I have explained above, the wireless button becomes blue and wireless assistant would be activated and indicates that the wireless is turned on. If I check in the Device Manager, I see the hardware details and driver wireless populated it and everything should work fine, but once I restart the computer, the wireless button would refuse to start. There is orange. If I try to check the State of the material status and driver WLAN on Device Manager, they would be is more filled it more and wireless assistant will refuse to start. If by chance he started, this would indicate that the wireless is turned off by the Device Manager.

    I had tried uninstalling the wireless LAN driver and reinstalled just in case the problem came from the software side but not solution. Just this afternoon, I have decoupled from the computer and removed the card WLAN, dusted it and replace it back, but the problem persists.

    The type of wireless network card is Atheros AR5007 802.11 b/g WiFi adapter. I noticed something this afternoon, however, after having checked the service manual for the computer, I realized that there is specific types of the wireless card compatible for specific regions. For example, the number of appropriate wlan spare parts which must be on my computer is 582564-002 and have this with references with the number of spare part of wlan on the wireless card available on my computer that begins with sps 452..., I realized something was wrong. I'll leave that to stop you guys from HP, but I really need a solution to this problem very fast because it's really annoying me. Thank you.

    Hello @LL_Cool_J,

    Thanks for the information!

    I don't know what you mean, when he asked if the model is 50xx or 40xx. Confirming the WLAN Module is a little difficult, because there are several manuals maintenance for this model.  I was able to refine the selection a bit, by comparing the numbers of spare part for hard drives.  Based on this REPAIR, the WLAN Modules you have listed, 582564-002, 593836-001, must be compatible.  However, I don't see the Atheros as option in this manual.  To be on the safe side, you can contact our telephone support HP.  Please use the following http://www.hp.com/contacthp and create a folder for your question and contact HP.

  • HP Pavilion dv7-1000ea Wireless problems - Urgent

    I just do a fresh install of Vista 32 bit on this laptop Pavilion dv7-1000ea.

    I have trouble getting the wireless operation.

    Device Manager is not recognizing that there is a wireless inside the laptop adapter, even if there is.

    The wireless light is orange. I could not do it turn blue.

    I installed ALL necessary drivers - nothing is reported in Device Manager does not.

    I have updated the BIOS and also tried it revert to an older version to see if that makes a difference or not.

    I assured that wifi antennas are properly fixed inside the computer.

    I tried to ensure without wire is activated in the Setup (F10), but there is no option for it!

    I tried to use HP Wireless Assistant to turn it on, but it won't let me open the utility.

    I tried enabling wireless through the Windows Mobility Center Control Panel, but there is no settings for wireless in there.

    Can anyone help?

    Sorry everyone, I managed to fix it. I took out the wireless card and put it again and then it was recognized and began to work.

  • HP Pavilion dv7-6135dx: windows 7 resettled after upgrading Windows 10

    Hello

    I bought my computer in 2011 at Bestbuy. In this computer factory settings had various applications, HP, HP Recovery manager, etc.

    Recently, last week my computer was attacked by malware and therefore, I had to restore my computer by using the recovery HP (Rebecca.exe) Manager. Meanwhile, windows offered to updgrade to 10 Windows. My computer is compatible, and that's why I decided to upgrade. Unfortunately, Windows 10 did not work too well with my computer, and so I contacted Windows Support team. They have reinstalled Windows 10 in my machine and remove the function back to Windows 7.

    Support of Windows 10 team could not solve the problems in my computer. I then asked to downgrade to windows 7. With their downgrading to Windows 7, I had to get all the drivers to make my computer function again. However, I do not have original HP and Applications settings my computer had when I first bought the computer.

    Is it possible to install all the parameters of HP and Apps? I tried to install HP Recovery Manager, however, when I do, it says "Softpaq does not apply to the system, no installed HP Manager."

    Help, please! My computer is running slowly. What should I do?

    ramirez_adolfo

    The best way to make your PC work again in Win7 is to do a factory restore using the HP recovery media.

    It is a set of DVD and a CD or a USB key, which will erase the hard drive (removing all data, applications and settings, reinstall the original OS, drivers and utilities for HP. In some cases, you will be able to order a USB instead of discs.  You must order at HP; they cannot be downloaded.

    It's the HP for your PC product page: http://support.hp.com/us-en/drivers/selfservice/HP-Pavilion-dv7-6100-Entertainment-Notebook-PC-series/5082216/model/5118973

    Down near the bottom of the page, you will see an entry for the command Recovery Media-CD/DVD/USB. Click on the symbol '+' to expand this entry and click on order to press for more details.

    Don't forget to read through the material in the linked thread before attempting the recovery: http://support.hp.com/us-en/document/c00707939

  • PC in a cycle of restarting after power surge

    Win XP SP 2
    NVIDIA 8800 GTS
    2 gig Ram
    P5N32 SLI
    Hi guys,.
    I hope someone can throw me a BONE here, because I don't know which way to go with this.
    Basically, power surge last night, my PC will now in a cycle of infinite when turned on reboot.
    I can't start in safe mode, as it hangs on the list of files. Cannot start last well-known, cannot start from the CD, at the risk of going as far as "Checking hardware" and restart.
    So, essentially I can't anything. I guess it's obvious that some hardware is fried, but I can't afford to replace things to chance - any suggestions on probable causes, or ways I can limit?
    Thank you
    KeV

    Hi KevTM,

    Method 1:

    I suggest to disable automatic system error reboot and check the error message.

    Prevents Windows from automatically restarting if an error of Windows to fail. Choose that this option only if Windows is stuck in a loop where Windows fails, attempts to restart, and fails again repeatedly.

    To do this, follow the steps below.

    To start Windows in safe mode, follow these steps:

    a. click on the electric start button
    b. to enter the Windows xp advanced startup option.
    c. when the computer starts up press and hold your "F8 key" who should bring up the "Menu Options advances of Windows". "»
    d. use your arrow to switch to "disable automatic system failure reboot" and press your enter key.

    Here, you will need to check the error message or you receive an error code.

    Method 2:

    Try to disconnect all the external devices connected to the computer except the mouse and keyboard and try to start the computer and check.

    Thank you, and in what concerns:

  • HP Pavilion dv7 7077ez wireless for windows 8 does not work after upgrade to windows 7 64 bit

    I have the broadcom card. I have try all the drivers and I still cant install drivers I see on household also setup.rul 342 of the installation error wireless start won't start. What should do?

    Hi Emilinator,

    More than likely HP won't to material support for Windows 8 on any system purchased before October 1, 2011.  Most of the Windows 7 drivers work in Windows 8.

    You can try this pagewhich provides measures to solve the problems of connection to broadband for Windows 8.

    Check out this page to see if your computer has been tested by HP with Windows 8.

    You can run the Upgrade Wizard, which will scan your PC and report on what is currently installed on your PC is compatible with Windows 8.  This guide was updated for Windows 8 provides lots of information which is needed for all those planning the upgrade.

    Good luck

  • Pavilion DV7-6175us: wire frayed at the power cord

    I just discovered this thread in my power cord cut tonight. Spare part number is 609940-001. As you can see, the white wire is broken, but the only issues I have experienced with my laptop is my AMD display driver to crash. But after you have reinstalled it and Direct X, as well as some versions of Microsoft Visual C++, the stability of video cards has improved considerably. But tonight, he crashed twice in 5 minutes, and then a few seconds later, just let Windows down and showed me a message of BSE on my display driver. I then looked at my power cord, and I find the severed cord. The severity of a problem is the next, and how long should I try and get a replacement cord? Thanks for reading and thanks in advance for your answers.

    Stop using it. It is a fire hazard and a danger to your laptop. Get a new one immediately.

  • HP pavilion dv7-6111eo: various missing drivers after having reinstalled Win7 64 bit on hp pavilion dv7-6111eo

    Aloha

    First of all... I'm not grumpy, geek or nerd... And I want to say these words to those who are at best.

    In this case, you need to see me as a kid in kindergarten, being taken by the hand and what to do, down on every detail. Sad but true.

    Without me know why, I've known several DLL files missing, and often obtained on those error messages.

    A pain in the neck, so I re-installed Windows 7 64 bit, because I didn't want to mess with these missing dll.

    After this relocation, I couldn't have the internet connection to my router. Fortunately, I have a fixed 10 year and longer, where I eventually found the driver I needed, so it works now.

    But now it seems that there are several other drivers missing or not installed.

    I got a little info, another post, it must provide information and hope that will be enough. If this isn't the case, then please let me know additional information which may be required, and where I can find those on my PC, so I can provide these.

    Missing drivers:

    Network controller;

    Hardware ID: PCI VEN_8086 & DEV_008B & SUBSYS_53158086 & REV_34

    SM Bus controller.

    Hardware ID: PCI VEN_8086 & DEV_1C22 & SUBSYS_1659103C & REV_05

    (USB) Universal Serial Bus controller.

    Hardware ID: PCI\VEN_1033 & DEV_0194 & SUBSYS_1659103C & REV_04

    I have 4 USB ports, but only work, others do not react, and I need all four at the same time. In addition, I would like to have everything in order after I had to reinstall Win 7.

    Thank you in advance for any help I can get. Just have in mind that I need the things dug into the paper.
