Waking from sleep

I'm on an MBP, and saw something said about turning off "safe sleep" solving the problem.

I recently read about some people having trouble waking up their Mac, in this case I'm on an MBP, and saw something said about turning off "safe sleep" solving the problem. I can't find any such setting and wonder if someone can shed more light on it or have other tips. Thx,
