No graphics card detected ?

[Avents]

Hi everyone,

I recently bought a Japanese MBP 13", 2.5GHz, 4GB RAM on amazon. Everything works well, there's nothing to complain about, except when I installed windows. The installation went fine with the Boot Camp package (all drivers are installed and such), however, when I looked in the specs (Windows), I couldn't find my graphics card ! I can only see Intel HD Graphics 4000 !

After verification, I can't find the Nvidia card on OS X either, and in Energy Saver I don't have the option to switch between graphic cards.
I also checked on the official apple site and I saw that my MBP version was equipped with the GT 650M card...

Can anyone explain to me how I can make my graphics card (GT 650M) appear so that I can install the nvidia drivers for it and be able to play heavier games than just minesweeper ?

Thanks a lot !

The 13" MBP does not have an NVidia 650M. Only the 15" versions do.

The 13" MBPs do not have separate graphics cards; they only have the integraded GPU. The 15" models have dedicated graphics cards plus the integrated GPUs

So, that's why. Thanks for the answers !
