Erratic "Battery Charging /Not charging"
Ever since I did a Mountain Lion update I´ve had various troubles with battery power. I reverted to Snow Leopard after installing an SSD and the issue did not go away. The indicator was saying "Replace battery". Immediately before the ML attempt my battery was showing 91% capacity, after the upgrade it started telling me to replace the battery!
So I bought an original Apple battery and replaced it. It seemed to work fine for some weeks but has now started saying "Not charging" sometimes. Coconut Battery if left open changes from charging to not charging. I checked for bad connections to the battery but that seems to be OK.
Is this a firmware issue caused by the Mountain Lion installation I did earlier on the original hard disk? Is there a solution?
