Well the battery is more than 3 yrs old, but it doesnt get a charge at all, if i take the battery out it still wont power, so im stumped how do i go about ressetting the PMU?
If the ibook will not power on with the battery removed and the powercord plugged in then it sounds like the ibook needs repair. Is there an Apple store in RI? If not there are 2 in Massacheusetts. One in Cambridge and one in Newton on Route 9 inside of the Chestnut Hill Mall.
This is what apple says about ibooks that don't power on & resetting the PMU.
