OK... so my fingerprint sensor stopped working for the BIOS power on a while back, not a big deal...
So I tried registering my fingers, and I received the dreaded e7210005 error, which tells me very little...
Following some advise on here, I uninstalled all the drivers and fingerprint app and reinstaled... only now I cannot register ANY fingerprints due to the error.
I tried creating a second admin acct follow other advice found on the MSFT forums, same error...
I am on Windows 7 64-bit, with Thinkvantage fingerprint software v5.9.9
HELP!!! I love my fingerprint reader and want it to work again...

What system is this (e.g. X220, X230, etc)?
If you go into BIOS setup, in the security -> fingerprint menu, and try to reset the fingerprint reader, what happens?

I received a success complete message when resetting the Biometrics in the BIOS.
I am prompted to enroll my fingerrprints, as all the previous ones were lost (note: should have exported the existing fingerprint data first). However, i am still getting the same E721005 error - sensor deviced used exclusively.

I have the same issue on a W530 and Windows 8.1 x64 after powerloss (removed battery by accident).
Upon reboot, I was unable to log on using my fingerprint. I now also get the same error (E721005 - device exclusively used message) when I try to re-enroll fingerprints in ThinkVantage. Interestingly, when I try via Windows 8's fingerprint, the first finger scan always succeeds, and windows reports an "unkown error" on second scan.
I have tried clearing the data in BIOS and reinstalling the drivers with no effect.
The device works just fine in Xubuntu 13.10 / fingerprintgui though, so this seems to be a Lenovo / Windows conflict?

not to be the bearer of bad news, but: http://forums.lenovo.com/t5/X-Series-ThinkPad-Laptops/Fingerprint-reader-software-error/m-p/1441783
looks like a hardware replacement is currently the only option...
i've got two M500 SSDs on OPAL, and logging in is a bit of a mission.

Its not hardware... its a permissions conflict in the software.
Hardware worked fine until an updated stopped it worked at BIOS powerup. Followed ill advise here to delete the fingerprints and flush the BIOS and reinstall to make it work again. BIG MISTAKE. (Note to self: next time export the fingerprint profiles first).
After the reinstall, THEN it stopped working.
Guess a full reinstall is the next step -- **bleep** I hate having to do that...
