i've done some searching and have tried all sorts of ideas for fixing this but no avail. After updating to snow leopard all of a sudden it says my battery needs to be serviced. My stats are 160 cycles with 69% battery life according to istat pro. Battery life the other day claimed to be around 80%. I tried running the battery to empty then recharging but still says it needs service. Then i tried removing the battery and the power cable, powering up holding the power button for 5 seconds to do the whole reset thing and that seemed to make the message go away for one cycle. Now its back and that solution no longer works. the about recommends taking it to the apple store. I feel like thats a wasted trip to the apple store, is there anything they can actually do to "service" the battery or am i missing something here?
