Fingerprint reader not recognized on laptop Pavilion dv4t-1400

In this last week, my fingerprint reader is no longer running on my laptop Pavilion dv4t-1400. I think that he stopped when last week he had two usb problems which are still pending - that is to say, under Device Manager, there are two USB keys with a yellow warning triangle and after trying to help out, he said: "Windows has stopped this device because it has reported problems. (Code 43) ».

I reinstalled the Validity Sensor software several times, but it does make a difference.

BTW, to the best of my knowledge, there had not been any new software updates before the USB errors.


This problem is solved when I turned off my laptop, unplugged the adapter and all external connections, removed the battery, expected a minute, resinserted the battery and restarted my PC.

Validity Sensor driver has been added automatically by Windows, and my fingerprint reader is now recognized and working.

  • Often fingerprint reader stops working after laptop wakes from sleep (Pavilion dv6)

    I am convinced that the fingerprint reader is fine. There must be a problem with the driver may, something inconsistent with a recent update of the Windows 7 software?

    The scenario:

    • Laptop works very well.  I put on standby when I'm done and use the mousepad to wake him up.  LED fingerprint reader blinks, and I can drag my finger to log on.
    • At one point, after a few times to put the laptop to sleep and wake, the fingerprint reader does not.  No flashing.  I slide my finger and the player does not respond at all - is not yet tell me that there was a bad reading.
    • If I login and log back in again, no change. However, if I do a reboot, everything is fine - the fingerprint reader works again.

    I watched over and over again for new drivers and installed.  Nothing seems to affect this scenario.   Unfortunately, this has started to happen about 9 months ago () and because of the sporadic nature of it, I was not attentive enough to know the 'precise' point in time when it started happening.  My instincts tell me that there was some sort of update software/driver along the way which is originally the fingerprint reader not do not work right.  I hope HP continues a relationship with these companies to fingerprint reader and can transmit these questions so that we can do a software update.  But... I don't know if it has been abandoned.  My laptop is still under warranty, but it would be ridiculous to send in just this problem.

    I hope that someone has heard of this on the dv6 and may know a solution.  Thank you!

    My system is a HP dv6-6145dx.  I am running Windows 7, with the latest updates.  The integrated fingerprint reader works on HP Simple pass 2011 v5.1 and Validity Sensor driver version.  When I try to launch the Simple passage interface, it loads the database, but then the application disappears.  I tried to uninstall and reinstall the software, but makes no difference with the issue, I noted.

    "If you keep an open mind, life will give you more opportunities."

    No problem, I am completely I shouldn't bother with Pass Simple version 8.  I advanced and installed version 6.  I did not yet get no joy, so I did a little more digging and found one more late Validity Sensor driver, version 4.3.304 (not noted in the list of update driver for my laptop model).  IT WORKED.  I can now go into hibernation and the fingerprint reader remains functional when the system is out of hibernation.  Previously, it was pretty much guaranteed became disabled.  So... it looks that my problem is now solved.

  • Pavilion dv6: fingerprint reader not working after update to Windows 10


    Recently, after the update to Windows 10 fingerprint reader works just on my Pavilion dv6. I tried other methods I found on the forum, and I'm looking for a driver get the fingerprinter reader to work. I tried to download HP SimplePass (which has been removed from my PC by updating the operating system) in the hope he would get my fingerprint reader to work, but no luck.  I also looked in the settings (in Device Manager) for biomeric devices, and I found a driver with an exclamation point, indicating it wouldn't work. So, right now, I need a solution to get my to work on a fingerprint reader.

  • Pavilion dv6500z: fingerprint reader not activated / work


    I have a HP Pavilion dv6500z (32 - bit laptop) running Windows Vista Home Premium.

    I have a handset problem and don't know if they are linked, or separate.

    (1) I'm missing an icon on the initial screen you are presented with when Windows comes first to the top, where you choose which account to connect to, before any screen of Login/PW. (see other comments below).

    This departure occurring at each "seed" (cold or hot) after running my laptop in safe mode, to analyze a different problem.

    (2) my fingeprint scanner does not... I get more no pop-up window if I accidentally slip a finger in the eye of the scanner.

    Normally, when I start my computer, I get to choose two icons: one with my name/icon.

    My account is a SysAdmin account, not a normal account.  I know what is its icon.

    I don't remember what the other one was... I don't think it was a guest since icons (images) choose account

    Since when creating a guest account will seem familiar, what was on the screen as the 2nd icon.

    I don't remember what is was, but think it was logging in using the fingerprint reader.

    Any ideas?



    This problem seems to be resolved.

    Here's what I did.

    At first, I just had an icon of my connection to the administrator account.

    After recording, I created a guest account.

    Once rebooted (hot and cold), my initial login screen had to choose 3 items:

    1) administrator account

    2) guest account

    3) finger slide to unlock a session ... it's the icon that was previously missing for the fingerprint reader.

    I went and turned off the guest account.

    I have closure for a few minutes and made a cold start.

    Icons for both the administrator account and the finger swipe to open a session showed the choice.

    This is how it should have been... How it was before the start in safe mode.

    Hey Midsyork,

    Looks like you run Digital Persona SimplePass flavor.

    Two things to try, in order:

    • Hard reset
    • Remove and reinstall the validity sensor 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.

    Check the software...

    If it still does not work, go ahead.

    • Control Panel > Device Manager > biometric devices > Validity Sensor > uninstall > delete
    • Reboot ...

    Validity Sensor V2.1.0.2

    • Install the validitysensorDriverinstallationpackage: 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.

    This can kick things hard enough to restore the Digital Persona software.  You can hit him harder, but first...


    What about the rest...

    You could consider running a full system scan.  I'm a demon for this.  I like a healthy file system.  It cannot solve the problem, but it will ensure that the issue is not a messed up system files, which CAN cause all sorts of unpleasant and troubled issues.  You do not really have to 'look' like a mother hen during analysis, look at the logs or 'DO' something.  He's going to take care of yourself and try to fix what it can.  The only time where that must involve it is things do not go well...  Is there a doc to help at the end to tell you what does this thing.  It is not harmful and, unless your system is broken, and it's going to die anyway, it will only make things better than they are now.

    scannow SFC

    Analyze and fix the system.  The sfc/scannow command. who will do - it will scan the operating system, looking for corrupted files and inconsistencies; He will replace or repair everything he can.  If it finds corrupted programs or libraries, it will try to correct them.

    • Start menu > all programs > Accessories > right click on guest > select ' run as administrator'
    • In the command prompt window, type (or copy / paste) sfc/scannow , and then press enter.

    (Note the space between sfc and the ' / '.)

    The sfc scan will report its findings and you can look at the results:

    • Open an command prompt (it doesn't have to be as an administrator):
    • Use the command copy to create a copy of file readable by the output:

    %windir%\logs\cbs\cbs.log copy %userprofile%\desktop\cbs.txt

    If "scannow" does not properly complete, try running:

    SFC /verifyonly


    Copy the results to a text file, extract the output file in Notepad and look for errors that could not fix the full scan.

    Help file for the System FIsland Checker command:

    The Windows Vista or Windows 7 System File Checker tool


    Good luck!

  • Satellite A200/W00 - fingerprint is not recognized by the software reader


    I'm running a laptop Toshiba Satellite A200/W00 (PSAF6A-0W00IN), and I recently installed my brand new Windows 7 Professional that I just bought.

    I found drivers for Windows 7 for my laptop on site and installed the Protector Suite QL, and very comfortable.

    Once I restart my computer after installing on the connection screen where the button scan fingerprints is connect it says "Cannot read the scanning device", or something in that sense.

    When I connect another pop up with the program on the bar showing the same thing, that my fingerprints, the scanner must be connected tasks. It is built into the laptop, it should not need to "plug".

    I tried to uninstall the drivers for my biometric device, and then on the analysis of the physical changes he immediately detected my fingerprint again reader and reinstalled the drivers of it.

    So my fingerprint reader is clearly working, but Protector Suite QL is not detect it. I don't understand why.

    Someone has discovered this problem or knows how to fix? I can't exactly check the State of my scanner as it is built into my laptop.

    You can use fingerprints (TrueSuite Access Manager) software and all the features it?
    You have registered your fingerprints? Some problems?

    Check the settings from there and be sure connect password option replace Windows with the connection of the fingerprint is enabled.
    In all this history it's really strange that only the windows fingerprint logon cannot correctly detect the device.

    I have a Qosmio x 300 with fingerprints. Have updated Win7 and everything works well. I may simply have more luck then you have. ;)

  • X201T fingerprint reader not scan

    Trying to put his fingerprints on my new X201T.  Each test, each finger - same results: green LED light scanner at the beginning, but after scanning my fingerprints, the orange LED blinks 3 times, and reported 'bad quality '.  I used scans of fingerprints on many laptops before - so I don't * think * I do this completely in back or something.

    I installed the new program to fingerprint reader (5.9.3, build 6264) the ThinkVantage System Update utility. Same results.

    Driver Manager shows "coprocessor (WBF advanced mode) digital footprints TouchChip" installed & working properly. He said that the latest drivers are installed.

    A possible problem - I occasionally get an error message saying "USB device not recognized - one of the devices attached to this computer has malfunctioned...". ». Shows Device Manager then an unknown device in the concentrator root (3 ports) USB / generic (6 ports) USB hub.  Is this something related to the fingerprint reader? Am I missing some device driver?

    Thanks for your suggestions...

    EDIT: I forgot to add - Professional Win7 64-bit, as installed Lenovo.

    My new x201T has finally - a working fingerprint reader!  Here's the scoop on getting this problem - the part which had to be replaced was part of the plastic screen, which also contains the fingerprint reader. According to Lenovo, the x200T both the x201T share the same exact part for the bezel of the screen number. But there are in fact two major differences:

    (1) x200T uses an AuthenTek fingerprint reader, x201T uses one of UPEK Inc. They have different connection cables.

    (2) the screen bezel x200T of course SAY 'x 200 Tablet' on this subject - maybe not a big deal, but I don't want the last year my x201T model # clearly on it!

    So now I have a screen bezel x200T & transplanted successfully into my fingerprint reader x201T!  Bravo for the on-site technician who understood all this after only two previous lost 30 miles out at my house. He ended up having to replace a cable additional x201T with the old version of x200T, to make everything work. We also had to install the drivers of different devices, as the fingerprint reader x200T is a manufacturer of completely different from the x201T.

    He also managed to carefully replace the sticker "x 200 tablet" of the new scope with that of my original unit, who said correctly 'x 201 Tablet '.

    Again - it has been a very frustrating experience. I don't understand why Lenovo is not a good new screen bezel with the correct new fingerprint for the x201T reader.  It should not require a creative technician find a way to hack the x200T spare parts to work in the x201T!
