Dv9700 HP Notebook PC: DigitalPersona Personal 3.0.0 "The fingerprint reader is not detected"

Some notes:

This computer is running Windows Vista Home Premium (32-bit).

The fingerprint reader is not an external piece of hardware that I plug in (it came with the laptop, and it is literally inside of the computer; checking if it is connected properly without voiding the warranty is impossible to the extent of my knowledge).

I've used this computer for six months without incident regarding the fingerprint reader. I recently reformatted the computer, and the fingerprint reader functioned fine for three weeks or so, until earlier today. There was no recent change in software or hardware, related to the reader or otherwise.

The first time there was any sign of any error, it made the "disconnect/connect" sound effect that occurs when one unplugs something from a USB port and then plugs it back in. My mouse ceased to function (until after a reboot) at the same time that this occurred, so I thought the issue was isolated to the mouse alone. (I have used the same mouse the entire time I've used the computer, so it should not be the cause.)

After rebooting, the mouse's wireless USB receiver began working again, but the fingerprint reader was stating that: "The fingerprint reader is not detected", and this has not changed except once when it randomly flashed that the device was working again, and then almost immediately went back to not being detected. (I say randomly, because this happened after I was reading a webpage, and not currently messing with anything.)

I've attempted reinstalling the software using programs and features, but it had the same "The fingerprint reader is not detected" message after doing so.

I'm simply out of ideas, though I admit that I may have simply failed searching for solutions on google, and one of you may find the solution within moments.

I appreciate any and all help that you can provide, even if it's merely confirmation that there's nothing I can do beyond sending it in for them to take a look inside.

    Suddenly and for no reason on the login screen I get "the fingerprint detector is not detected". I have not downloaded software nor have I reformatted...etc.
    This problem started out of the blue.

Cody's suggestion about rolling back the device driver works perfectly. I too had downloaded the windows update version and installed it and it turned out incompatible. Rolling back works great! Definitely try it.

I found this on another site and it worked for me!

"Ihad the same thing happen, and determined that you have to go back toan earlier version of the Authentec driver to make it work. I tried 4versions and the only one that works with DigitalPersona is 7.9.0.4,dated 2007-08-28. You can find it on the HP Website. It appears to beavailable in a number of Softpaqs, such as sp37815.exe, sp37812.exe andsp37920.exe. Maybe these different versions are meant for differentmodels, but they appear to be the same driver. There is a brand newdriver available from Windows Update, but it doesn't work. I hope thisworks for you.

To fix this issue go to device manager, then under personal identification devices, right click on the authentec fingerprint reader.

click on the driver tab, and click the roll back driver button...should fix the problem for you...I also tried EVERYTHING you guys mention but to no avail....this works!!!

Hello, i have a toshiba laptop and the fingerprint reader isn't working..how do i fix, please?


The driver could be out of date. Try opening device manager. If you are running Windows 7 or Vista, click on the start menu and type device manager. If you are running Windows XP, click on start, control panel, system, then the hardware tab, and device manager. Scroll down and open the plus' until you find the fingerprint reader. When you find it, right click on it and click update driver. Tell it yes, you want it to search online for a new driver.

Driver cannot detect this device


Hi,

Does the computer detect the fingerprint reader at all? If it shows up in 'device manager' with a yellow exclamation mark then you have a driver issue. In this case try reinstalling your fingerprint reader driver software. If your device is not being detected at all, try reinstalling your usb drivers from within 'device manager' then plugging your fingerprint reader in once again. If this doesn't solve your problem, you will need to have the reader tested as it is most likely faulty.


Best wishes,

I have a problem with my hpdv5 1205tx my current windows is vista i repormat in windows 7 now my problem is my digital personel fingerprint was not connected i already down digital personel 4.11 help me...


If you have installed either 64 bit or 32 bit, then you have to run the installation as administrator.

To do this, just right click on the installation file and choose run as administrator.

If this did not help, refer the below steps:

  • Download version 2.01 of DigitalPersona software
  • Install on existing system
  • Export data
  • Boot into Win7
  • Install 2.01
  • Reboot
  • Reset properties for each of 7 EXE files
  • Reboot
  • Register a finger print
  • Import data saved in step 3


  • Download from here:

    http://download.cnet.com/DigitalPersona-Password-Manager/3000-18501_4-201746.html

    Step 3:

    Export is available as an icon choice in the system tray. Save to a file for use in Step 10.

    Step 7:

    The run properties for each of the 7 EXE files in the DigitalPersona install need to be adjusted. The files are:
    DPAgnt.exe
    DPConsol.exe
    DPExpImp.exe
    DpFpLogonManager.exe
    DpHost.exe
    DPRunDll.exe
    DPWinLct.exe

    Select each and set as follows:
    • Compatibility tab
    • Press ã¢â‚¬å“Change settings for all usersã¢â‚¬â
    • Select run in Vista mode
    • Select run at admin near bottom
    Repeat for each of the 7 EXE files.

    Nnags.

    DigitalPersona Personel Fingerprint reader not detected, HP Pavillion dv6706tx Vista 32, DigitalPersona Vers. 4.11.3805. All drivers up to date. In device manager cannot find Personal too. Any idea how to...


    To install DP4.11 first uninstall all previous versions on your system and turn off authentec and biometric services in Windows Services so you can then delete the digital persona folder in Program Files (assuming dpagent was running) and uninstall fingerprint driver, then delete Fingerprint sensor folder in Program Files reboot and system will find and install fingerprint driver then double-click to execute and install DP4.11 setup program. (Note: all previous saved passwords for websites will still be listed in digital persona - you will not lose any passwords from your previous installation)

    Fingerprint reader activated and has me locked out after reboot


    hi

    here are some steps to disable finger print reader..


    The easiest way to disable the Microsoft Fingerprint Reader’s default operation is to rename the highest level program file.


    To do this, the DPAgnt.exe program must first be terminated.


    Step 1: Press Control-Alt-Delete, so the Windows Task Manager comes up.

    Step 2: From the Windows Task Manager, click on the “Processes” tab.

    Step 3: Find and highlight DPAgnt.exe by clicking on it.


    Step 4: Right click on DPAgnt.exe, and click on the “End Process” menu, as seen below.


    Next, you have to rename the DPAgnt.exe program so it won’t be loaded at boot up time. The Microsoft Fingerprint Reader’s program and driver files are located in the “C:\Program Files\DigitalPersona\Bin” folder on a Windows XP Home or Pro hard disk.

    Step 5: Click on the “My Computer” icon on your desktop.

    Step 6: Type into the “Address” bar input area, and enter “c:\Program Files\DigitalPersona\Bin”

    and hit return.

    Step 7: Single click on DPAgnt.exe

    Step 8: Right click on DPAgnt.exe. Then click “Rename” from the popup menu.

    Step 9: Change the filename from DPAgnt.exe to DPAgnt-BAK.exe.

    i hope you do it....

    please rate me

    thank you.

    Lay your finger flat down, with the first section of your finger above the reader, then keeping it totally flat, gently but firmly and slowly, glide it across the reader, moving it toward your right side after you have ran it across, as make an "L" shape. Be sure to go slow, and keep it flat.
