i was sitting in a dark room with my 12" rev. b powerbook resting on 2 books for airflow (rousseau and mill if anyone was interested - i wouldnt be) well back to the story, i leaned back in my chair and then under my laptop was a green glow. i thought how odd having not seen them and i was sure it couldnt be the glow from the underside of my jbl creature speakers so i decided to investigate further (the tension is building). i turned it over to discover that there are 5 green led's on the battery (ooh!), i thought how exciting and then got back on again with my work. a few days later (today) i wasnt at my desk and suddenly i got pulled to looking at my 5 mysterious led's on the battery again to find they were not on (shock), i then got drawn to a little silver button at the side of them which i promptly pressed (dum dum dum) for them to light up again (yay!). so i have worked out that they must be some form of battery power monitor. sorry about they long boring post but as you can probably tell i got quite excited by them!
