After three weeks of use (November 2010) the problem arised: My fingerprint sensor can't be found to register fingerprints despite it is installed (Hardware manager says it works properly).
I tried many things in order to solve the problem, even with new hardware but it doesn't help.
What I already did:
The problem is really strange, what else could it be? Went something wrong in the registry? Communication problem of the USB interface? Problem inside Windows WBF?
Many thanks in advance for some hints!

does it show up in device manager under biometric device? open the device in device manager and check the power settings. unclick "allow windows to turn off this device to save power"

Yes, the the fingerprint sensor appears in the device manager, it says that it works properly, the driver is up to date and I unclicked the power save option turn off.

At the moment when I click on a certain "finger" in order to start the register process with Lenovo software, then the error messange comes "Fingerabdrucksensor kann nicht gefunden werden" (fingerprint sensor can't be found, E7210005 "Operation is not allowed by operating system policies."). The fingerprint sensor doesn't get active (no green LED).
There is a similar error if I use the Protector Suite software from UPEK: after I entered my windows password, it says that identification number of the interface doesn't correspond to the device. So the software can't connect to the sensor.
Yes, I replaced the palm part (the part infront of the keyboard with touchpad and fingerprint sensor) already, because the local Lenovo support thought about a hardware malfunction, but it still doesn't work.
I did many Google searches to this topic, one says that a new administrator account could register fingerprints, because the built-in administrator doesn't support Microsoft WBF. But it didn't help unfortunately. http://social.answers.microsoft.com/Forums/en/w7security/thread/05dc659a-3397-4e72-8fba-46832da667e0
Does anyone have some more ideas?

i assume you already did this, but you don't mention it. in control panel, under biometric devices, change biometric settings, you do have biometric switched on, right? and also, "allow users to log on using fingerprints".
