Replacement battery is not working, neither is old. Why?
I have been doing tons of research and cannot find an answer that will solve my problem. My battery went out a few months ago when I put in a new hard drive. I did not mess with anything other than the hard drive. My battery has not worked since then.
My Macbook only works when it is plugged in to the adapter, otherwise, it shuts completely off. The battery icon has a 'X' in it. I have checked all setting and the laptop does not even recognize a battery at all. I just bought a replacement and installed it, still having the same issue.
The closest Apple store is a 3 hour drive and I do not have the time to make that trip right now. I have also called and Apple states they would need to see the laptop.
Any help or advice is greatly appreciated.
Is this a good question?
