Don't know whether this is linked, but soon after updating to 10.5.6, my battery indicator keeps flashing between the percentage, and saying Not Charging. Could this be my battery, which is the original one supplied with my 1st Gen Whitebook? Or maybe something to do with the update? Anybody noticed a similar problem? Have checked battery contatcts, and all seems well. Don't want to have to buy a new battery if i don't have to!
