    Another newbie question but I never understood this... can someone explain it in a bit scientific way? Will it damage my battery's life to leave the computer plugged in? or does it matter at all?

    Can I run the computer plugged in always without any adverse effects?

    I have a MacBook 13.3 2.4GHz and two chargers... the 60W and the 90W that I still cannot find where to plug :confused:

    Thanks for understanding and explaining these newbie questions...

    i run mine plugged in most of the time

    just be sure to run the batt down like once a month to maintain its health charge wise

    It runs off the AC when plugged in. The battery has a smart processer in it, to check stats. So don't worry about it to much, just keep it away from heat.

    mine is on the power pretty much all day every day. I rarely take it off the ac. I should but i don't

    No. If you don't use it on battery power often (like once a week or more) then be sure to calibrate it every few months or so.
