Charging light won't stay lit on E1505

I have a two-year old E1505/6400 that has a sudden battery light and charging issues.  The battery is typically used for no more than a minute at a time. It drained completely after accidentally being left unplugged.  When I plug in the adapter to the computer, the charge light flashes orange momentarily (either once or  ~three times), and then goes to green for about 30 seconds, and then turns off.  I can charge the battery for 30 second intervals while in hibernate. (It is now showing 1% charge, which is up from 0%.)  The battery has three consecutive green lights on the "fuel gauge" which indicate a 60% charge.  The battery meter reads 1%.  The bios says battery is "functioning normally." 

Has anyone seen this problem before?
