[ubuntu_studio] How to stop a laptop battery from draining even when plugged in?

view story

http://ubuntuforums.org – Ive got an old Mac Powerbook G4, and ive noticed lately that the battery continues to drain even when its plugged in while im using it. When i stop using it the battery charges back up. Can you have to many accessories plugged into a laptop so that the battery on it will drain even when the computer is plugged in? I currently have 5 external hard drives connected (3 of which drawing from their own power cords) my iphone and my ipod. ___________________________________________ asus laptop keyboard sale acer laoptop battery sale asus laoptop battery sale ca430097ca12 (Hardware)
