    Try this

     

    Resetting the System Management Controller (SMC)

    Resetting the SMC on Mac portables with a battery you can remove

    Note: Learn about removing the battery on MacBook and MacBook Pro.

              1.          Shut down the computer.

              2.          Disconnect the MagSafe power adapter from the computer, if it's connected.

              3.          Remove the battery.

              4.          Press and hold the power button for 5 seconds.

              5.          Release the power button.

              6.          Reconnect the battery and MagSafe power adapter.

              7.          Press the power button to turn on the computer.

     

     

    or this depending on the battery situation.

     

    Resetting the SMC on portables with a battery you should not remove on your own

    Note: Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).

              1.          Shut down the computer.

              2.          Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.

              3.          On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.

              4.          Release all the keys and the power button at the same time.

              5.          Press the power button to turn on the computer.

    I'm going to assume you need a replacement battery...

     

    Macs wont start unless the battery works.

    I have a macbook pro that has the same problem and i was able to get it started by taking out the battery and then just keep on pressing the power button. the battery wont charge but the computer will still turn on (note: this process may vary on time so be patient)

    MacBooks will startup without a battery installed as long as the a/c cable is connected.
