I can also back this up. Bad idea to even try regardless of your GPU or CPU.
Way back, I fried a fairly decent 4 core laptop with a gtx680M. They simply lack the cooling to making mining possible.
Not worth it.

I'm glad I am not the only one who learned a hard lesson about mining on a laptop. The cooling just isn't designed to handle full loads constantly.
