Blackscreen no chime
Hi all, I tried to get my daughter's PB G4 1.67GHz Al book to start up... Here's what she told me: recently, every time she used the pb with the power cord, any slight movement and the of the cord would cause the pb to go off and she had to anchor it so that she could charge the pb. I thought that she might have a short. The cord wasn't the original... it looks like the cheaper one you can get from OWC. She bought a similar cord on ebay and when she plugged it in, nothing happened. This replacement cord has a green light on it, which didn't light up. She then took the black extension cord from the cord set that was failing and tried to use it with the new cord. She still got a black screen but now a whine came along with it. I wasn't sure if there was a HD failure so I inserted a 10.1.4 startup CD, the only one I have besides 10.5 and it's probably the wrong one to have tried. Now the pb has a CD stuck in it. PITA! I thought that the PRAM might have gotten corrupt. I took one of my working original equipment power cords and connected. Black screen with whine. I zapped the PRAM... same result. I looked up how to reset the PMU for this model, reset PMU... and got a black screen with whine. I can also hear the whistle of the CD spinning up each time I try to start up... but can't eject it. The whine doesn't seem to sound like a HD problem. If it were the HD, wouldn't we get a bong, and eventually a question mark because a HD couldn't be found? I don't know where to go from here except to Apple... I hope that I can get this solved with your help.

I hope that I can get this solved with your help. Thanks in advance. Search this group. I have the same PB with very similar problems. Some folks here have helped going on 3 years or more now, and I can't still can't sort it out. Though I'm inclined to think it's the logic board that's gone nuts, particularly, the IDE channel. If I put the HD in an external case, it boots and works fine. But the optical drive won't work. So, give it a go, get/buy an external Firewire drive...ONLY AFTER YOU'VE HEARD FROM OTHERS...and then boot from that and see what happens. Might be a different problem but it's worth the try. -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
