Battery is not charging Power source: power adapter
I am very confused by my MagSafe power adaptor.
Often I get : "Battery is not charging Power source: power adapter" with an orange LED on the adapter, Last time this happened the battery was 65% charged
Right now I have NO led on "1:33 until full. Power Source: Power adapter"
Sometimes, I get a dim green LED
Each of these becomes normal on removing and reseating the adapter.
The spring loaded pins are perfectly sprung and are clean. The receiving bit of the laptop is clean. The adapter clicks in perfectly. The battery is new enough (and this happened when the battery was replaced anyway, and beforehand).
This happened since I got a new style adapter, the one where the cable is parallel to the Macbook, not the one where it sticks out at 90 degrees. I have two of these, and it happens with both.
MacBook Pro (13-inch Mid 2009), OS X Yosemite (10.10.2)
