  • Pavilion dv6 fingerprint reader has stopped working

    My fingerprint reader has stopped working. I can open the Simple pass identification program but when I click on fingerprints, it indicates 'identity check' with an hourglass on the top of the icon of fingerprints, and no matter how long I wait, that's all that happens. All advice appreciated.

    "Where you go, there you are."

    Hi Mikey,

    Looks like you're running the Digital Persona of SimplePass flavor.

    Two things to consider / try, in order.

    If the reset works, you don't have to reinstall the driver...

    • Hard reset
    • Reinstall the driver

    Hard Reset:

    Sometimes, all you need to do is the computer suddenly.  This method works for a variety of connection and "glued" program issues.

    • Disconnect all the external devices first.
    • Remove the AC power and battery
    • Press and hold the power button while in the minus 30 seconds
    • Reinstall the power supply for the first start only * see Note
    • Power on - connect
    • Next time you shut down the system, replace the battery.

    * Note: You can ignore the little battery aside.  If you wish, replace the battery the first time and do it with her.

    The pilot, from your Internet site:

    Validity fingerprint sensor Driver sp52354 V2.1.0.2

    • Install the validity sensor Driver installation package: it if called sp*.exe - the package will be most likely located in the downloads folder.  If you have control of "Admin", you can highlight the package and "double-click on ' to install it, otherwise just right-click, select"Run as Administrator"and install.

    I hope this helps!

  • on dv6 fingerprint reader has stopped working after installing Norton 2012

    Fingerprint reader has stopped working after installing Norton Internet Security 2012 on both of my notebooks from HP.

    Product name: HP Pavilion dv6

    Operating system: Windows 7 64-bit

    Error message in Device Manager under biometric devices in Device Manager displays an exclamation mark beside validity sensors (WBF) (PID = 0018). The following message is under the general tab: "Windows cannot start this hardware device because its information of configuration (in the registry) is incomplete or damaged. (Code 19) ».

    Driver is present and seems to be up-to-date.

    Appreciate your help.

    I have finally isolated the problem of my software lack of HP dv6 fingerprint reader. I think Norton Removal Tool, available online at www.symentec.com/nrt, was the reason. I am sure this conclusion because the exact same problem occurred after I installed Norton Internet Security 2012 on laptop HP same as my wife. I tried, in vain, to uninstall and reinstall the driver for the biometric fingerprint device provided by Validity Sensors, Inc.

    After spending a day and a half to try to "solve" the problem, I decided to restore my system and go back to the prior agreement of the point of the installation of Norton. Thank you HP to make this process quick and painless. Don't forget that if you installed anything after the restore point, it will have to be reinstalled.

    Fortunately, there's a less intrusive on CD of Norton removal tool. This utility uninstalls an older version of Norton you are requested to restart and then installs the latest NIS. It is a method of removal safer that wide brush offered by the Norton Online link, which wipes everything remotely suspect.

    After reinstalling Norton Internet Security 2012 from the CD, everything works as it should, including the fingerprint reader.

  • Fingerprint reader has stopped working after update vV1.0.3.49

    I recently downloaded from Toshiba and installed Fingerprint Utility V1.0.3.49 (tc00407400c.exe) and since my fingerprint reader has stopped working.
    The software opens but usually recognizes my fingerprints and can not connect any other way.

    Have uninstalled and reinstalled several times and same result.

    Device Manager says device works ok.

    May I ask what model phone you have and what system do you use?

    Probably, you need to delete stored fingerprints and after restarting again, you should try to register new fingerprints using the software update of fingerprints.

    For each driver in the list, additional useful information is displayed: load address of the driver,

    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
