''I believe you may have a cracked battery.'' I had a MacBookAir that acted strangely and that's what it turned out to be.. someone squeezed their laptop on top of mine in an overhead bin before I coud get them to stop. It acted ok unless the case was torqued. ''If this answer is acceptable '''please remember to return and mark it'''.''
