Hi, guys It's my first post here and I reeeaally hope you can help me out. I've read everything I found on the internet about battery problems with the Macbook Pro, but nothing solved the issue I'm having. So, I have a black Macbook Pro 13'' 2006, serial number 4H7046F4WGM. The power adapter that came with it, a T-shaped MagSafe, broke a couple of years ago. Since then, I've been using the L-shaped one that came with my dad's Macbook Air. It was working just fine, but then my battery stopped charging. So I replaced it, because it was actually really old. Now I just got a new battery compatible with my Macbook but it won't charge! I don't know if the problem is this new battery or the adapter. Does anyone have an idea of what can I do???
