I've made posts over at the Apple Discussion boards but have no luck with responses. I participated in the battery recall but now my battery life is pathetic. If the battery gets to be below 50% it shutdowns. No warning, just black. I would definitely not call this normal behaviour. When I get to an outlet and turn the computer back on, the battery is at 1%. I don't get it, where did that 49% magically go? Like if I can only get 1 hour out of the battery, this is no longer a portable machine. Any thoughts?
