E7470 with the latest BIOS and latest drivers for everything else.TPM version is 2.0.
Put the computer to sleep (close lid) and try to use fingerprint to log in works for a while. After about 5-10 sleep/wake, the fingerprint stops working and Windows reports 'Something has gone wrong." Windows 10 reports in the Event Viewer:
Log: System
Source: TPM
Event ID: 14
The device driver for the Trusted Platform Module (TPM) encountered a non-recoverable error in the TPM hardware, which prevents TPM services (such as data encryption) from being used. For further help, please contact the computer manufacturer.
Only way I have found to fix this is a reboot. Would like to see if there is a TPM firmware upgrade or a new driver that fixes this. Sort of annoying to reboot just for the sake of rebooting....I keep a lot of applications running.
Is there a Dell TPM driver for this? It is using the Microsoft driver 10.0.14366.0 dated 6/21/2006. I can't find one on the Dell support site.
