For last 2 days I've experienced really weird behaviour of a1185 battery in 2007 Macbook Black. Fully charged battery drains from 100% to ~60% after I turn off my MB (complete shutdown) and turn it on few hours later. The strange is the fact, that in sleep mode everything is ok, battery drops maybe 1-2%. It has 43 cycles, "condition: normal". In addition I discovered that my magsafe is probably broken because indicator light sometimes turns off or the battery is not charging - shaking the adaptor brick helps, but is it possible that defective magsafe caused this weird draining I described above?
