i have an ibook and i started folding last spring...i enjoyed folding although i didn't get a whole lot done, i liked being involved though and i think its a great thing to do...however after i had been folding for some time my computer's battery pretty much died. it would freak out and go to sleep at like 80% then it would say it was at 0% if i tryed to wake it up. i got a new battery under 1 year warranty and now its been working fine. i was curious if it died cause i was folding on it almost constantly. i would usually turn folding off if i unplugged my ibook however there were a few times when folding ran while i was on battery power. anyway when i joined macrumors folding initally we were pumping out a measly 2000 points a week and now its gotten ridiculous. i would like to join back up but i fear my battery will die again and i don't have apple care so it would come out of my pocket to replace.... what do you think?
