i just got my macbook pro 17" and i was wondering if they make cases for them? hard shell cases i mean. I think i seen one a little bit ago that was black. Is that the only one available? I was hoping to buy a blue one. Also, the charger. It has a green and orange light. What do they indicate? Mine is orange right now, my guess would be orange is charging and green is full? And is it safe to leave it on the charger? and is it better to shut off the macbook completely or just close the screen and put it into sleep mode? sorry for all the questions, it's just my first time having a laptop and i really don't know much about them. I want my battery to live as long as it can. thanks!
