    Hello,

    I bought my new macbook pro in november and the battery was fine. It lasted 5 hours. But now, when I fully charge it, it only says that my battery will last 2:30...

    I happened all of a sudden. What can I do? I tried to re-calibrate it by fully uncharge it and then fully charge it...

    Any tips?

    Thank you!

    John

    What kind of stuff are you doing on it? Is Wireless on? Is Bluetooth on? How about display and keyboard backlights? Are you using the 9600 or the 9400 video card?

    I know that if I'm browsing flash sites, display brightness about half down, wireless on, bluetooth on, using the 9600 I will get only 2.5 hours of battery life at best.

    Cheers.

    calibrate your battery. If that doesn't work, then its just time for a new battery. Time to schedule an appointment at apple ;)

    I assume you calibrated it when you first got it, and every month after as Apple recommends.

    Post us a screenshot of your Battery health, cycles, remaining charge etc and i'll tell you whats wrong with it and if Apple will replace it for you.

    Check if you have any processes on your Activity Monitor taking up 100% of CPU. I've had this exact problem as you when I had stuck print jobs.
