So I'm sitting around before a class the other day, happily typing away at a letter on my tangerine rev b ibook when it just dies, no warning or anything. I try to turn it back on but to no avail. Then, I plug it into a near-by wall plug and it comes back up but shows that my battery is completely drained. Odd, since it was full according to the indicator not too long before it died. I let it sit overnight, plugged in and charging. When I turned it back on, the indicator still shows it charging and says that it's computing how long it's going to take to finish charging. If I try to turn it on unplugged, it won't work. The first time it died, I lost my time and date, but subsequently if I turn it off and unplug it for a while and then turn it on (when it's plugged in again, since it won't start up on its own), I still have my time and date. I guess this means that the battery isn't COMPLETELY dead, but why shouldn't it have fully charged over night? And why doesn't it seem to take any charge at all when it's plugged in?
