my mac book pro wont turn on battery charger light flashing green
This is most likely caused by a power issue with the DC-In or logic board. It’s also possible that the internal battery or MagSafe adapter itself has failed. The first step would be to try a different MagSafe adapter. Followed by a DC Board replacement, then battery replacement. What is the history on the machine? What are the last three figures of your serial number? When you press the battery test button, what do you get? Did you have any problems leading up to this failure?
My battery died while I had USB peripherals plugged in now my machine won’t start up at all. I still get battery light and the mag safe light works
