Hi Folks, I'll get straight to the point: Is there any harm in using a Mac Laptop with the power chord plugged in a lot of the time? I've just got a MacBook Pro, and I use it a lot of the time near a plower plug, so I naturally plug it in to stop the battery level from dropping and accelerating the natural life of the battery. When the light turns green, does the power stop going to the battary or what exactly happens? Any opinions? Cheers, Steve.
