I just bought a Lenovo Y500 about a week ago and I noticed that the laptop only uses both graphic cards when it is plugged in to the AC adapter. However, when I unplug it, it'll use only one graphic card. So how do I get the system to use both cards even when i'm unplugged?

In order to use the SLI (two graphics cards), it requires the 170w adapter to run at maximum performance. The battery can only run one graphics card because it needs more power to run two.
