I have a mid-2009 13" Macbook Pro with 8GB RAM.  I have the odd situation of the power indicator on top right of screen showing that the power adapter is plugged in, but the percentage indicator stating that the laptop is "not charging."  I have been working on the computer for several hours and the laptop has only charged to about 27 percent according to the battery health application that is runningI have.  It says the battery has gone through 281 cycles and is 2.4 years old.  It suggests the battery should still charge to 92 percent of its potential.  The battery is warm as is the power adapter cube, so something is happening.  The little light on the end of the power cord is green but only two of the little green dots light up on the left edge of the computer. 


Any ideas if this is a battery, laptop, or power adapter problem?  Unfortunately, I don't have a second power adapter to test that idea.  Thanks for any suggestions. 



MacBook Pro, Mac OS X (10.7.4)
