Hi, I'm not sure if this is should be in hardware or software, so I apologize if this is in the wrong catagory. I have a "5,1" Late 2008 Aluminum MacBook 2.0 Ghz 2 gb RAM I just replaced the stock 160gb hard drive with a 500 gb Seagate. Everything is working perfectly except for one odd issue: While plugged in, the MacBook says it is charging normally and appears to actually be doing so. However, when I unplug it, it shows the plug icon on the battery as it does at 100% charge and says "(Not Charging)". Power management wise it also behaves as if it is plugged in. So, as you can imagine that is quite annoying as it doesn't dim / sleep when it should if left sitting and I can't see my battery % when it is unplugged. I have looked EVERYWHERE on the net to no avail. The MacBook is no longer under warranty so no dice there. I have also checked my energy settings as well as reset the SMC. Thanks in advance for any help!
