Hello all! newmacbook and in love. as far as loving a computer can go... calibarting the battery, the instructions read: bring to full charge, keep there for two hours, let drain to no charge during use, let sleep for five hours. --to let the battery rest. and then bring to full charge again.... ... well i can't bare to be away for five hours... can't i just take the battery out and run off the cord? i can't think of any reason why not. and am a little surprised why it wouldn't say so in the manual... thanks, r.
