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.

I have tried all possible methods of uninstalling the driver and re-installing. But its of no use. Also Rollback driver button is disabled. I dont know how to rectify it. Can anyone help me out.???

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!!!

I am using Compaq CQ40-108TU model, I have changed the OS to Windows 7 (32bit) after that the Imaging device is not appearing in the device mgr.. due to this my notebook webcam is not working. any help? ...


Hi, welcome to FixYa!

You can try installing the driver for the webcam. Try to download and install the driver from this:

http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?lc=en&dlc=en&cc=us&product=3791887&

Choose Windows 7 (32-bit) as your operating system.

If Windows 7 is still not recognized the webcam, you can try download and install webcam software such as Cyberlink YouCam.

Thanks for using FixYa.
