MacBook Pro (Mid 2014, uses a MagSafe 2, 13inch) won't charge but the adapter shows a green light, not dim but normal strength at all times.
On the battery information page it said Amperage (ma) was -986. I checked this three times in 5 mins and it changed to -35, then - 384. The laptop was plugged in at all times.
MacBook Pro with Retina display, OS X El Capitan (10.11.5)
