It doesn't work on me as for the solutions you provided. The macbook pro is not responding, battery indicator - no lights, charging - no green light or any light, (charger is working fine on another mac), macbook pro just don't start up

?i have the same problem, were you able to find a solution?

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

Macs wont start unless the battery works.

Any solution? I have the same problem on a 7 month old computer.

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.
