Hello there,
I just bought a PowerBook G3 Lombard and used it with my iBook clamshell power adapter, which I know works. When I plug the adapter into the PowerBook, sometimes I see a green light on the left hand side light up. Once or twice, I could hear the hard drive spin up. However, I have not been able to reproduce this in the last 20 or so attempts. In a single instance, the screen turned on, but it had some streaking lines across a grey background and I could not see anything. In more recent attempts I have not been able to get any sign that the PowerBook is turning on at all (i.e. the hard drive makes no noise whatsoever, etc.). Sometimes, I see a green light when I plug the power adapter in, and sometimes there is no green light, or it only appears briefly. I am really trying to figure out what component might be the problem. My first instinct is to assume that it is the sound/AC card, which the power adapter plugs directly into. That might explain why there is some variation in terms of the experience. However, I cannot come up with a suitable explanation. I have tried numerous things beyond replacing any specific components quite yet. One of my first strategies was to disassemble the entire computer to make sure that all the connections were solid. After reassembling the computer, my experience was much the same. I have also kept the PRAM battery unplugged at different times, because I read somewhere that a bad PRAM battery can sometimes affect the power up. Does anybody have any suggestions as to what the culprit might be? Do you think I am right in believing it might be the AC/sound card? From your experience, might it be something else? Thank you for your advice in advance.
