I bought a base MBP 14 in late December and received it in early January. I have been using it for about 3 weeks and today noticed that it is no longer charging to full capacity by default. I have used it plugged in 99.9% of the time. The Magsafe connector is now always remaining orange and the charging is on hold. Should I charge it to full capacity on occasion, or should I only do this when I am going to use it with battery power? Thanks for any help.
