Hi I have a Macbook 1,1 2Ggz, 1Gb ram all software updates done which has decided today to show calculating (or 99%) next to the battery icon and the charge light on the charger plug is red all the time.The battery has 4 solid green lights and 1 flashing green lights on it and does not seem to be getting hot. Any ideas what might be going on? I don't remember seeing this happen before and it has been going on for a couple pf hours now. Thanks for any help.
