I've never experienced this problem so hopefully someone here has and can tell me what's up. Anyway, my 2008 Aluminium Macbook has always charged fine. But recently, when I plugged in the charger, I noticed that the light on it would fade in and out and the notifier at the top would go from "Charging" to "Not Charging". I unplugged it to see if there was something wrong and still, it keeps doing it. The crazy thing is, when I have the monitor closed, the charger stays stable and charges the laptop. But when I open it back up, it goes back to cycling between charging and not charging. Has anyone experienced this before? Any solutions?
