On board Graphics Detected not Graphics card

[syaoran7li]

Hey everyone.... How r u all???

well my friend bought a laptop it has on board graphics and also a additional nvidia graphics... now when i run game the on board graphics card is getting detected and not the nvidia card.. i tried in bios but in the display part there are only 2 options 1 is optimus whic allows bot nvidia vga and intel vga to work and the other one allows only the intel vga to work... so is there a way to make games recognise nvidia or can i disable onboard graphics through device manager??

thanks....

Without knowing what laptop your talking about........

Most of the new ones use the integrated graphics for general use, then kick in the discrete graphics when it's needed, this saves power and keeps it running cooler.

When you play a game, the Nvidia graphics will kick in automatically if it's needed.

Did you change bios to Optimus?

I don't know, only thing I can think of is re-install the graphics drivers for the 540gtm.
