Hi All, Just recently purchased my first ever Mac and I'm really happy. Got a quick query. I want the overall usability life of my battery to last as many years as possible. When the charger is plugged in, and the battery is at 100% charge, does the power travel through the battery? Or does the power bypass the battery completely leaving to not being used at all? Second question. I leave my MBP at home and don't travel with it. Would you recommend I shut it down when not using it, or just close the cover to put it to sleep? Someone discouraged me from doing the latter saying that it uses up battery re-charge cycles, but I'm not sure? I always keep the charger plugged in when MBP is asleep. Thanks for your help in advance.
