    I've had that happen before... usually it was just because the mag wasn't connected real well. I think for me its because I have a plastic case on my macbook pro so it doesn't always get a real good connection.

    usually yes it's either because of the adapter not connected all the way or the light is simply going out or the power adapter isn't supplying enough power. is the computer charging alright?

    Right now I am plugging it. The light is still a faint green. In 4 hours, however, the % bar moved only like 4. From 13% to 17.
