    I recently got myself a Macbook Pro (got screwed on the price though...damn craigslist) and I'm wondering what the most efficient way to charge is.

    Right now I don't plug it in unless the battery's close to empty (even if I'm near an outlet). Good or bad? Should I always leave it plugged in if possible?

    My USAGE: Mostly at the desk. Will sometimes take it out to class, library....nothing over 2hours without an available outlet.

    (PS. Aside from the charging wire...What is that other thick cable that comes with it??)

    I've had mine for over 7 months and it is plugged in virtually 100% of the time. Battery health according to iStatPro is 98%. I may run it down and recharge it completely every couple months or so, but I see no problems leaving it plugged in when it's on my desk.

    Is it bad to do that? Let it die (almost) before recharging?

    I am just the opposite. I use mine unplugged 99% of the time. I only plug it in to recharge. I plug it in at night to fully charge it, and have to charge it sometimes durning the day. I use mine at the kitchen table overlooking the yard, my favorite chair in front of the TV, outside on the patio. I don't really care about charge cycles, or percentages. As long as I am getting 3 1/2 - 4 hours, using wifi, and brightness 100%, I am happy.

    Depends upon your habits/tendencies. I bought a laptop because I wanted to be mobile so much of my time is spent "unplugged", working off the battery.

    When I can, I'll leave it plugged in and work off the "wall power" just so that I'll have a full charge when I want to get up and go.

    Is there a habit that's worse than the other? I'm not a stickler for 100% efficiency either...I just want to take care of the battery and know if I'm doing something actively wrong.

    What if during calibration you don't exit an app when the mbp goes to sleep? Is that rly bad? My mbp went to sleep with The Office season 2 DVD playing. :(

    It's OK to do that. Just be sure that you save if you're using typing a paper or something else that needs saving.

    BTW, the Office is an amazing show :)
