I have a 2Ghz macbook with the 950 gma. I recently formatted and reinstalled tiger. Since then I think my battery life is worse than before. I looked at my system config and my battery update version is 1.3. Looking at other posts, it looks like 1.3 is only for the macbook pro's. Why would I have this version installed, and do I need to downgrade it to version 1.2? Thanks for any replies.
