I'm trying to get some help/advice on what to do about my 2009 MacBook. Last month out of nowhere it suddenly started dieing when unplugged from power adapter. A quick google search told me it was a battery problem, so I ordered a new battery no problem. That worked for about 2 hours, and then it started doing it again, dieing whenever it's not plugged in. I did a reset on the computer, and nothing. A summary of the problem: * Macbook sees the battery, will charge the battery until full but will shut off immediately if it is unplugged from the AC adapter. * Macbook will not boot up unless plugged in. * Battery shows up fine in the computer and fully charged. * If I put a new battery into the MacBook I have the same issues. * Resetting SMU and PRAM does not help. Does anyone know what's happening and how to fix it? My closest Apple store is two hours away, which would require hassle. I would love to just be able to figure out the issue and fix it from home.
