ThinkPad T-420, T-520, and W-520 Nvidia Driver Installation

When loading Windows 10 (most recently 20H2), many of the needed drivers (but not all) are auto-installed. Many can be improved upon by sourcing drivers directly from Lenovo, other from manufactures themselves. The most "problematic" can be the Lenovo Hotkey drivers, the Ricoh Multifunction Card drivers, and the Nvidia GPU drivers.

The Nvidia driver installation is quite finicky. The Standard Lenovo driver for the Optimus "System" may work for the Intel drivers, but fails for Nvidia. When installing the Nvidia portion of the standard driver for Optimus 23.21.13.9125_391.25 (g5do01ww.exe), a message appears that the hardware cannot be found (the problem seems to be the SUBSYS part of the PCI ID).

Trial and error has shown that the default drivers from Windows 10 may work, but might be improved upon.

By trial and error, the following work - for these *specific* boards.
