Respuesta a "not charging and would not work without being plugged in"My 2010 macbook pro was doing the same. Green light was on the MAG PLUG but the charge stayed the same percentage like it was charging. I used my power strip with the power plugged in. Switched the power off and on looking at the power on the laptop. I slowly would look at the meter and when it read not charging the laptop automatically search for a charge the MAG LITE turned orange and started charging back up again.
