    Is it best to leave my computer on or off and plugged in or on the battery? My last iBook had a battery life of about 12 minutes after a year or two, so I am keen to avoid this happening again if possible.

    Did you/do you calibrate your mac batteries?

    It arrived about a week ago and I will be calibrating it for the first time today, then once every month or two after that.

    I never did it for the iBook (wasn't my computer, I just used it a lot and left the maintenance to other people).

    Any advice re: my original two questions?

    Leaving it on (sleeping) and plugged in shouldn't do much harm to your battery. Your battery has a finite number of charge cycles - if it's above 95% then you won't be charging it having it plugged in.

    I run mine plugged in the majority of the time. It's coming up for 3 years old and I still get just over 2 hours on the original battery :D

    hey guys ,,, how do you calibrate your battery ?
    I just got mine new Macbook Pro 2.33 like 4 days ago ...
    can anyone point me out how to do that ? Thanks
    I already on my 2 cycle ... so Im guessing the more cycle the worst the battery gets right ?

    I use my MBP C2D plugged it all the time that shouldnt be a problem. Im guessing.

    Thanks.

    Calibrate your battery:

    And yes eventually every cycle is a tiny step to a dead battery. :rolleyes:
