I recently purchased a Lenovo Y580 and installed a 120GB SSD drive with a fresh install of Windows 7. I downloaded and installed all of the drivers from Lenovo's site, but am still unable to use the "graphics" button on the laptop; the button that's near the right speaker. I take this to mean that my Y580 is not switching between Intel and Nvidia.
How do I enable the automated graphics card switching, where the system chooses whether to use the Nvidia card or the Intel onboard graphics?
Press the revoery button before startup to get into the Bios menu.
From there you want to move down to get the list Configuration.
Then look for Graphic device.
Make sure it is on "switchable" graphics instead of "UMA" graphics to have the Nvidia graphics card active.
Also in the Nvidia Control panel you will need to pic each program individually so that the switchable graphics will run on INtel or Nvidia.
