[QUOTE="MacInWin, post: 1881989, member: 396914"] Don't know and it doesn't really matter. The fact is that when plugged in to a proper external power supply there is sufficient external power both to run the MBP/MBA and charge the battery. How the circuitry manages the power and any switching from mains to battery isn't perceptible to the user. [/QUOTE]
