To keep plugged in or not to keep plugged in that is the question.
New MacBook Air. I've received conflicting info and read some as well. So, is it 1) only use the adapter when charging the battery, but not using the system, or 2) use the system regularly running off the adapter, or 3) some combination of, say through the course of a week, running off of the adapter for a time and then running off the battery?
MacBook Air, OS X El Capitan (10.11.4)
