won's start up at all, dead
Powerbook won't start up (about 5 years old)... no sound, no light, nothing. I have tried resetting PMU, can't do the PRAM reset... no joy with either of these). I recently replaced the power adapter, but should be fine as is the same model as my old one. Problem started when I left ethernet cable plugged in overnight. The power chord glows amber only, and looks like the battery has no life, but it did have some life before the problem started (would work for a couple of hours without power). I would like help diagnosing the problem and the likely repair cost. Gratefully!
