    I purchased a Lenovo Y510p recently with dual GT 750m. The first time I opened the NVIDIA Control Panel, the SLI option was there. However, the second time I booted the laptop it just disappeared. Does anyone know how to fix this? Thanks in advance.

    From what I understand about SLI, it is not compatible with Optimus (at least in the High end SLI Laptops). You may have to disable Optimus (Intel GPU) via your BIOS or a keyboard shortcut (Fn + F1 through F12 Maybe). It could be that the connection in your smart bay is loose as well.

    Download and install the latest Nvidia drivers, (320.49 I think), open Nvidia control panel click 3D settings >Set SLI and PhysX configuration, and it should have an option to update SLI configuration
