About a month ago my Powerbook g4 quit recognizing the power adapter. I had an after market adapter that was kind of beat up, but the proper voltage was still reaching the pin. I ended up sending my notebook to apple to fix under the protection plan. All they did was replace my battery and send it back. That was fine and dandy as i was able to use my computer until the battery died. I decided maybe it was my adapter so i ordered a new after market adapter. Still a no go. Sent my computer back to Apple. This time they replaced the logic board. It still doesn't work. Could it be that my adapter (the brand new one) is bad? Or is there still something wrong with my laptop? Every time I call apple they want me to go to an Apple Store, but unfortunately the closest one is like an hour away. Should I send this thing back for a third time?
