Well, here goes. My first post. I have a 15 inch aluminum PB (from Nov '03) that I don't use as often as I should. I often leave it off for weeks at a time (bluetooth and airport off). When I turn it back on the battery power shows 0% and I have to recharge it immediately. Why is the battery losing power when it is not running? Is this bad for the battery/computer? What can I do to stop this? I don't want to leave it plugged in all the time if it's not doing anything. Any advice would be great. Thanks.
