I have been trying to maximize the life time of my laptop battery. My approach to that is to almost use up the charge in the battery then immediately charge it. It is always annoying when the battery have 5% left, because that's when it hibernates automatically. Can I change the settings so it won't do so? Also, what are the differences between "Total Charge" and "Primary Charge" of a laptop battery; there are usually more "Total Charge" than "Primary Charge". Do you think this method is effective? What else can I do?
