Our facility has deployed whole hard disk encryption to all laptops. This program initiates a preboot login screen. Customers on Docking stations would like that preboot authentication screen to appear on their external displays.
I have update their BIOS, installed the latest Nvidia drivers and set their bios from "Nvidia Optimum" to "Discreet"
Then I set the display to "dock 1"
Press F10, save, reboot and everthing works.
Customer removes laptop from docking station and brings it home. There is no docking station at home so the laptop's LCD is all there is.
Customer returns with laptop to work in the morning, drops it in the docking station and boots up. The preboot screen is still on the laptop.
The end result is the BIOS has to be accessed every morning to make it boot to the external display.
What is changing the BIOS back from what I set it to? How do I force it to stick?
