    Hi All,


    I did a Thinkvantage system update today with BIOS update as well as replacing the Norton Internet Crapware with AVG free and on reboot I no longer had the fingerprint sensor but instead get, "Cannot find fingerprint sensor device. (E7210005)" (I downloaded the FPR driver from an IBM link here and was then told that there was a compatibility issue on installation.)


    Edit: After trying to reinstall the device with ThinkVantage Toolbox's Device Manager, I get the message from TouchChip Fingerprint Coprocessor (WBF Advanced Mode) Properties that the device status is:


    "Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)"


    Any help appreciated...thanks from a noob.

    SOLVED:

    Opened: ThinkVantage Toolbox (TVT) > Diagnostics > Device Manager Alerts > Device Manager

    Then from there to Biometric Devices > TouchChip Fingerprint Coprocessor > right click and Uninstall.

    Back to: TVT > Diagnostics > System Tests > Quick Hardware Check (I think)

    ...this revealed that the TouchChip Fingerprint Coprocessor was not installed > choose option to fix/install.

    Sorry sarppan, not sure how to help you. Under Biometric Devices, it's the 2nd option down, right after battery. Perhaps yours hasn't been installed yet. Try doing the last step to install:

    Back to: TVT > Diagnostics > System Tests > Quick Hardware Check (I think)

    I don't know how to fix my finger print device, it's in active now. I had called up Lenovo customer care, the support said that it could be a hard ware issue and I need to send the system to them to fix it. As I am using it for my work, I could not send it to them just to fix finger print reader. However, I don't believe it is a hardware problem. I don't find biometric device option in my system, does any one know from where can I download biometric device driver and fix it?.
