    Hey all!

    I have a Black Macbook bought in the summer of 2007. It has 3 years of apple care.

    Now, I'm just wondering if my battery running out too fast? Before, I used to always put my Macbook to sleep (closing the lid) and the battery never seemed to run down.

    However, at the moment I'll turn it off for a day and it will lose around 10%! I've had it "sleeping" for about 5-6 days now (I use a desktop PC at home) and turning it on today, it has 0% and has to be charged.

    Is this right?

    Maybe I never noticed it before as my laptop would go off at night, and back on in the morning every day when it was my main computer.

    Opinions please!

    How many cycle does your battery have? And how much capacity at full charge?
    Check those information and the battery status under the "About this mac" menu, then by clicking the "More Info" button and selecting the Energy section.

    Try calibrating the battery as described by Apple:

    It says the cycle count is 225.

    The full charge capacity is 4847 (mAh).

    The battery status is "good". So, are both of those any good?

    Will try calibrating, see if that helps.

    Your battery seems to be fine.

    Sleeping always drains the battery.

    Try hibernating instead. You can find free applications that will hibernate when you close the lid.
