The battery icon of my 3 days old 15" MacBook Pro shows 99% even though it is plugged in and fully charged. The magsafe light is green. Today, the percentage dropped to 98%, even though the computer has always been plugged in when turned on. Both OS X Lion and Windows 7 (via Boot Camp) show the same figures and the menus say that the battery is fully charged and not charging even though they also say 98%. Is there a way to solve this?
