Can I still a (t420) fingerprint reader?

I recently bought a t420 and did install a windows cleaning 8.1. Everything works well except the fingerprint reader. I went through all that have the post about people of questions, but I'm starting to wonder if I have another one. Nothing is displayed in the Device Manager and trying to erase the fingerprint data in the bios it is not found either.

Is the Center middle button directly and especially the touchpad fingerprint reader (it has 7 white dots on it)?

N ° it is the middle button of the mouse on the trackpoint. If you have a fingerprint reader, what it would look like a visible location under the arrow key down

  • T420 - fingerprint reader does not read the skin dry or wet

    I used the fingerprint reader of my old T61p for years with great success. It didn't matter that my skin is dry or wet, or even if my fingers are a little fat - identification has worked well.

    Now with my T420, I noticed that the fingerprint reader detects my fingerprint only, if the skin on my finger is 'normal', i.e. it does not detect the reading if my fingers are wet or dry. When my fingers are dry, I must always first lick my finger and then wide, this helps.

    It's very annoying feature - is possible to configure the fingerprint reader to be a little less sensitive to the dryness of the finger skin?

    Go to the Lenovo Fingerprint Reader software and look for a slider between Dresser and protected. This move to Dresser; It should contribute to the sensitivity.

  • How can I disable the SimplePass fingerprint reader for now?

    DV7 6143 cl, Windows 7 64 bit.

    The computer is several months old, and yesterday I finally had the time to look at everything on the machine to see what was useful.

    For the first time I opened SimplePass (AuthenTec version I think) and implemented with my Windows logon.

    It works and can be useful in the future, but not so much right now so I would like to disable or turn off the drive without uninstalling the software.

    Also, just curious, the implementation of procedure I used was not like any tutorials on HP sites.

    It is best to leave things as they are as long as the software is quiescent. It is a simple matter to restore your registration when you want to use the logins SimplePass. Merry Christmas!

  • Fingerprint reader - Windows 8 - HP Pavilion DV7 connects not

    Have searched high and low for a solution to my problem to scan fingerprint - tried instructions on many site without solution.

    Please help-

    I have a HP DV7-6c27cl (Pavilion) - purchased 11/2012.

    Updated from 8 to 64-bit Windows to purchase and fingerprint scanner quit job with TrueVision HD webcam.  HP driver update for webcam works perfectly - running.

    Software HP SimplePass is responsible for the current 5.20.233a (DigitalPersona) version.

    East went to HP and downloaded the new driver (SP58834) for the fingerprint reader.  We sought their updates using the specific model of this laptop and he gave me this driver up-to-date with.  Software starts but no joy on the drive...

    Simple pass still said "the fingerprint reader is not connected.  "Connect to the reader."

    Earlier today when trying a number of different patches I had a tap of biometrics in my device manager and another in the Panel... on one of my attempts to find a solution, I deleted these.  Is gone now.

    Don't know what to do from here.  It doesn't seem to be any solution on the Web Digital Persona site either.

    Please help and thank you.

  • Dell Studio 1737 Webcam and fingerprint reader

    I recently bought a refurbished Dell Studio 1737 and its big, but it did not come with thewebcam or fingerprint software installed and no disk, so, although I have

    installed the latest drivers, they cannot run as there is no software. I managed to find and download Dell WebCam Manager, but then I installed the

    pilots, he said that there is no device detected. I can not even find the fingerprint reader software, I understand his Digitalpersona called, but I had no record of such or

    software with my laptop. Can anyone help? Thank you

    Hi GSNYDER70,

    I have a Dell Studio 1737 and I changed the original Palm with another fingerprint reader without a provided, naturally original Dell. When I downloaded the driver Dell Web site package that I surprised... There are only drivers, but not the software! The original software provided with the computer laptop Studio 1737 is Digital Persona of Digital Persona Inc. I asked a question to Dell technical support, but no response because I am out of warranty. On the site Web of Digital Persona, I found a software that can work with the fingerprint Authentec AES2810 reader model but you have to pay for it. Quality on the web I found another user of Dell which solved the problem: you can download the Digital Persona version 4.10.3790 of the HP Web site software! Here is the link:

    I installed it and now have the fingerprint reader work perfectly. If you have any further questions please ask me. Best regards.

  • T420 Windows 8.1 fingerprint reader

    Lenovo Fingerprint Reader software is not Windows 8.1, any help?

    Hi all

    I found a solution for the integrated software for Windows 8.1 finger.
    So, currently, it's for my T500 but it could work with T420.
    According to Microsoft, the finger native connection manager works if the finger sensor driver is based on the 'Windows Biometric Framework'.
    Then, I remember that on the AuthenTec support site, it was possible to download a compatible driver, but since the recovery by Apple, this support site has disappeared.
    We have a chance that the internet has a backup for drivers

    From the link below, you can find the driver for Windows 8.1-compatible finger.
    If the link does not work, try searching for the name of the driver on your favorite researcher: "WBF3.4.4.1027."

  • X 1 carbon Touch Fingerprint reader 'can not find the fingerprint sensor device' e7210005

    Hi all

    I have spent far too long trying to solve this problem by myself and need to reach out to someone who may have solved this problem. I read tons of questions similar online and restarted from dozens of times after trying many different things.

    I have a carbon 3444-GCU Touch who can not see his fingerprint reader. It used to work when it is brand new, but after many updates from lenovo and windows, it now does not work:

    I'm on Windows 8.1, with all updates.

    No problem in Device Manager.

    Coprocessor (WBF advanced mode) Fingerprint TouchChip installed under thin biometric devices.

    _Not_ power management value disable device to save power.

    The bios is 2.61.

    I suspect that the problem is very low, because even the BIOS can not find the device trying to implement.

    If I have the lates BIOS, but it can't see the camera - what can I do?

    Thank you all...

    you have a faulty drive.

  • Can I put the Satellite P100-240 with internal fingerprint reader

    I have a Satellite P100-240.
    Although he did not come equipped with material to print finger scanning, it has clogged the hole in the box where he would go.
    So I wonder, can I get the hardware scanning separately and adapt it to the laptop?

    I don't see any option for the material to be sold separately on the Tosh site and I'm not even sure who makes the hardware for them so I can source it independently.

    Can we offer here advice or information on this operation?

    Hello

    You are right. Some P100 units support the fingerprint, and some units have been delivered without this feature.
    As I m not wrong not these fingerprints can be upgraded

    But to be 100% sure you should ask the local ASP (authorized service provider) for details.
    But in my opinion you can not put the laptop with fingerprint reader.

    Good bye
