Hi Everyone, I got my MBP 2,5 Ghz Penryn 3 weeks ago and it's my first Mac. However I noticed something funny. I work at my desk 99% of the time, with the power plugged in. Ofcourse, the battery should remain fully charged because of this, but when I start it up the next morning, the battery has lost 1% charge. How can this happen? I am using the adapter as much as possible to prevent the battery from having to charge and recharge so much, extending it's life. Any ideas?
