My classic MacBook Pro (4,1) is having battery issues. Age of my mac is 20 months, health is around 50% and the load cycle count is not being updated after a full recharge. (1) When I unplug the adapter, often the health pops up from 50% to 70-75%, but when it's nearly drained it's cut back to 50-55 again %. (2) When it states that it's fully charged, the load cycle is not increased, it is stuck at 175 since the last 30-31 charges (I really counted this). (3) The f**kers at my "genius bar" don't have a clue, but they never have any clue. Probably they don't know what the word "forum" means since when you're at a "genius bar" you've become a deity, at least that counts for my mac store back in Groningen, The Netherlands. So there it is: does anyone have any clue what might be possibly going on with my battery?
