T420 running 285.62 nvidia drivers - optimus included?

[ Edited ]

Hi all. I have a T420 and wiped it clean for my own Win 7 64-bit installation. While running the driver updates from Lenovo's driver site, I noticed separate drivers for the nvidia card - looks like the "regular" drivers and the optimus separately. I didn't install from there. Instead I went to nvidia's site, like I always do, and installed the latest driver for the NVS 4200M. As a side note, my system also has an integrated Intel card. All seems to be good so far, but haven't tried any 3d apps.

 

I assume the new driver has Optimus included in it? I have an icon that shows Nvidia GPU activity, which is really cool. Lets me determine what 3d programs use the Nvidia GPU. 

 

Am I all set or do I need to make any BIOS changes? I just don't want my Intel card to start working in the middle of a 3d app, yet I don't need the nvidia card working while in 2d.

 

Edit: Just noticed these drivers - 290.53 - should i be using them instead? http://www.geforce.com/Drivers/Results/40617

Edit2: Installed the 290.53 beta drivers - no probs so far. 

 

Thanks.

I think http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS014142 is still the latest supported Lenovo driver package.
