Biometric device problem
I am using an HP Pavilion dm4-1125, and I can use the Fingerprint Reader to log into my Windows account. However, control panel does not show Biometric Devices, and HP SimplePass program has stopped working, not allowing me to manage my fingerprint data. Looking into Device Manager, under Biometric Devices there is only the Validity Sensor, which tells me it has the latest drivers installed.
I don't know what happened, it just suddenly stopped working one day. It was exam week and it did not really stop me from doing anything on my computer apart from making me feel really has no fingerprint reader. However now the problem is that I can't configure my fingerprints anymore.
