These are the specs to my laptop. From what I know, it's not really for gaming but I'm able to play SC2 fine on medium resolution. I checked canyourunit and everything passes but the graphic card. I checked blizzard website and my graphic card wasn't on the unsupported list also so I'm wondering if I can run it without lag or any problems.
