why does the light on my battery charger change from green to orange after a few seconds?

Why does the light on my battery charger cable change from green to orange? The battery continues to accept a charge when light turns orange.

MacBook Pro (15-inch Core 2 Duo), Mac OS X (10.5.8)

Green = not charging.

Orange = charging.


Note that if your laptop is pulling enough power (using CPU and GPU heavily) the light will turn green because the power adapter cannot provide enough power to charge your batteries in addition to keeping the system going.


In fact, you can drain your batteries even with the adapter plugged in with the 17 inch Macbook Pro if you push it hard enough, although I have not noticed this problem with my Retina Macbook Pro.
