Hi.. I just bought an used dell e7450. I've already restored it using windows 10 menù and the system is working fine but I'm encountering some trouble with windows hello. Initially everything were working fine with the fingerprint reader but after 3-4 reboot the Windows hello option in settings -> Account -> Sign-in options disappered and the fingerprint doesn't work anymore. Can someone help me reinstall or reconfigure windows hello? I already tried to uninstall drivers and reinstall them.
Another question. How can i check if i have the right drivers and software? For example in device manager the keyboard listed is "Standard keyboard PS/2", every time i use hotkeys function no "pop-ups" are showed on the screen and how can i set keyboard backlight timeout for example?
