Hey guys, I just got my Macbook today, and I'm having a weird problem. I had the Macbook plugged in for many hours. I disconnected the power adapter and it shut down, I tried turning it on, but no go. I then plugged back in the power adapter, and it started right up. I looked in System Profiler, and it's telling me "No battery is installed." When I look at the top menu, it has the battery icon with a big "X" in it. I'm assuming that the battery is no good, which boggles my mind because it's basically a brand new MacBook, but I just wanted to make sure?! However, if I'm missing something that's right in front of me, feel free to enlighten me! Thanks!!
