I have a question about the charger you got whit the SR MBP. If I remember right it should light red/orange when charging and green when it don't charge. I don't know if I have a problem here whit the charger or the connector in my MBP. I have seen this week that it sometimes turn of the light and I only have a black lamp on it. My battery is 100% charged haven't used it this week on battery yet. When it turn of the light I just unplug it and connect it again and there I have the lamp back on again.
