OK guys - I am looking for an answer to that age old Mac question: Do I put my macbook to sleep at night or not? Wouldn't it be better to just shut them off completely? I am sure you guys have seen this question bouncing around the web. Why is it important? Here's why I think it is important: 1.) The "sleep" feature on macs draws considerable battery power, so if your macbook is sleeping overnight, and is not plugged in, you are using up to 6% of your battery life each night, which translates over time into wasted battery life cycles, in my view at least. 2.) If you leave you macbook plugged in overnight, this raise a whole range of other issues. The lifespan of the adapter may be shortened, or you run the risk of overhearing the laptop. 3.) And this is the big one - do macbooks even need to be shut off? Does it improve system efficiency, and life span of the hardware components to avoid frequent shut downs, or does putting your macbook to sleep on a regular basis have no benefits over and against shutting it down every night? So the question remains - to sleep or not to sleep. I would appreciate your answers, thoughts, and comments.
