MagSafe adapter 60w only charges while magbook pro is logged on
I purchased a new MagSafe adapter for my mid 2012 MacBook Pro 13 inch and upon charging, the led shows green then blinks amber, if I log on it charges as normal with the amber light,Why does it not charge while log off, do the MagSafe adapters have to be conditioned?
MacBook Pro 13", macOS 10.14
