    I have recieved a m17x as a replacement for a faulty m1730, system is great apart from the following issue.

    When I boot the system it uses the intergrated graphics. Device manager shows ONLY the 9400.

    When I open the NVIDIA control panel there is no option at all for SLI.

    I reboot, head into BIOS and disable the intergrated graphics. System boots and SLI is active. Device manager shows the 2 cards, also NVIDIA control panel now displays both cards and the settings.

    If I reboot the system the intergrated card becomes active again and no more SLI, am I missing somehting?

    Two options I can think of:

    1) You're on battery power which on most of the drivers disables the 260/280Ms by default (if I recall correctly)

    2) For some other reason the system is defaulting to the "save power" setting in the hybrid SLI instead of "Boost Performance". You should be able to switch between the two via an icon in the system tray.

    Going from an m1730 to a M17X is a pretty big change. As others have stated, you hav ethe ability to switch between the cards using your function keys or command center (stealth).

    Thanks,
