Hello All, I have a white 500Mhz iBook, whose battery seems to be all but dead. It manages to hold about 20 mins of charge... Does anyone have any miracle tricks for reviving an old battery? I enquired about re-packing it, but that was going to cost about the same as a new one (I have bought a second (new) battery, but want to see if I can give the original a bit more life) Thanks, Wiebe
