I have the MacBook (13-inch, Aluminum, Late 2008). January 2011 I purchased a new charger. Everything was going fine until last night. 1. It will go from charging to not charging. Sometimes, when I moved the charger cord it would start charging(almost like a short). But, I think it's much more complicated than that. 2. It will randomly shut off. I have the charger connected because I'm trying to get it to charge... it only shuts down when it is not charging(but when the charger is connected) 3. The System Profiler says that the charger is NOT connected. When I tried to do system updates it said to connect the charger. It was plugged in but it won't read. 4. I also checked the battery info in System Profiler. It says the condition is "good". 5. I have all the updates up to date. 6. I've shut it off and reset the SMC. 7. I have a hard time turning it back on. I have to press the power bottom at least 3 times before it starts back up. Nothing seems to be working. I plan on taking it in to a store, but I have midterms THIS WEEK and this is the worst time for me to make an extra trip. Thankfully I have access to my boyfriends computer.
