Not sure what the issue is yet, but the power adapter for my Macbook has developed a quirk.
The little light on it has a mind of its own. Normally it should be green when fully charged and amber/orange when charging. It should never be off.
Mine has been expressing its independence lately and turns off randomly. Strange thing is that the laptop continues to charge and seems to function OK. It shows no sign of an actual problem with the power supply from the laptop. It just seems to be a problem with the LED.
I was checking this support document from Apple and everything seems OK that I can tell. No stuck pins. Not incredibly dirty or anything. And it has been working fine on the same outlet since we've plugged it in. No signs of any damage that I can see.
I suppose I'll just have to keep an eye on it and take it in if it gets worse. Very strange though.
