Just noticed this problem last night.. My Mac isn't charging! I was playin' last night (PS3) when i noticed that my mac just keeps on goin into sleep mode 2 - 3 times, then i noticed my charger indicator isn't lit (green or yellow).. I tried to unplug it then plug it again but to no avail... Can't figure out what just happened.. Any ideas with this kind of problem? Can't say if the problem is with the charger or my mac itself.. Please help me guys.. thanks in advance..
