You can get the nVidia drivers to work; however, you will need to get modified .inf files. These are available from:http://www.laptopvideo2go.com
- be very careful if you want to go this route because some of them don't work and cause lockups.
These .inf files support overclocking and bunches of other features.
The standard files from the nVidia website don't support many of their mobile versions. They are generally left to the OEM's.
You could use the desktop drivers by selecting the video chip in Device Manager, selecting Update Driver, pointing that to the directory the desktop driver setup was installed to, and selecting GeForce 440MX or something like that.
