Hey everyone... I seem to have a bit of a problem. I have a 2.2 ghz Santa Rosa MBP, which is only about 6 or so months old. As a rule, I usually keep the thing plugged in, running off the power adaptor. I don't tend to let the computer fully drain; most of the time I just plug it in at maybe 75% charge, 50% charge ect. So today, I had my computer unplugged and figured I would wait till the power drained to about 15% or so, maybe even less, then plug it in for the night. However, before that even happened, at about 30% battery power the computer just abruptly shut down with NO WARNING whatsoever. I even tried to power back up and it just turned off again. At this time, the button on the battery that shows the power level did show one out of the five lights light up. This is making me nervous. Its really not that old of a machine and I don't constantly plug and unplug the computer. I really have no idea why this is happening. Does anybody know what the problem might be and maybe a possible fix?
