Hey y'all, I read the instructions for calibrating the c2d mbps, and i had a question. My base line c2d mbp doesn't go into safe sleep. It gives the warning around 2% and then drains to 0% and then just shuts off. It used to go into safe sleep, but not anymore. Is this a problem (it's wierd that it doesn't safe sleep anymore)? I plan on calibrating it tonight, and it popped up in my mind. Also, after 5 or more hours when you plug the power cord back in, do you leave it off or turn it on?
