I tried to install the video driver for my T520 notebook. Unfortunately I can't find the driver for the card.


My product number is: 42405bG and hardware numbers are:


PCI\VEN_8086&DEV_0116&SUBSYS_21D117AA  (8086 == intel)

PCI\VEN_10DE&DEV_1057&SUBSYS_21D117AA (Nvidia)


This system is a Windows 7 machine; Optimus does not function in Windows XP, so a choice between discrete (high power consumption) and integrated (no external monitor) in BIOS has to be made.

It is recommended that users install the latest Intel or NVIDIA drivers and that Windows 7 is used instead for this system.
