I've got a late 2007 macbook (santa rosa), which I've managed to get through 697 charge cycles. It still manages to get a few hours off the mains electricity, however recently the battery-related processes seem to have gone awry. Firstly, I no longer get "plug me in" warnings when there's 5% of charge left. Instead the macbook just shuts itself off, which can be annoying! Secondly, the light on the magsafe doesn't always work. It will be orange whilst charging, as usual, but then after a while will simply go out. The machine is still charging when the light is out. I've checked system profiler, apparently the health of the battery is still "normal," but the problems seem to suggest otherwise! Anyone had this before? Can I get away with resetting something like the SMC or is it new battery time? Thanks!
