The DV6000 has, "256MB NVIDIA(R) GeForce(R) Go 7200" - Taken from

Starcraft's minimum requirement is: 128 MB PCIe NVIDIA® GeForce® 6600 GT or ATI Radeon® 9800 PRO video card or better.
Your video card does have 256 MB of ram, but it's a go series 7200, which is worse than the 6600 GT. A 7200 go series has a Video Processor Core Speed of 450 MHz. A 6600 GT has a 500 MHz core speed. You are under the minimum requirement in the GPU aspect.
Other than that during my research to make this post, I saw some other users mention on a forum that the 7200 Go series card is a low low end card. Benchmark site articles were dated all the way back to 2006-2007, which tells us that the technology you are using is outdated, and is worse because it's a laptop. Unfortunately, you will have to either purchase a new laptop, or a new desktop. A desktop would be a cheaper to build machine that could keep up with SC2, whereas if you're looking at getting a laptop I would stick with a gaming laptop if you are planning on gaming.
