I was just given a used PowerBook G3/233, http://www.everymac.com/systems/apple/powerbook_g3/stats/powerbook_g3_233.html I kind of suspect that the yo-yo AC adapter that came with it isn't the right one, M7332 http://www.powerbookmedic.com/YoYo_Style_Power_Adapter_m7332-p-16183.html The battery was working a few months ago, but now it's dead and I can't charge it. The PowerBookG3 is listed here as being compatible, but I'm really having to jam the plug into the computer pretty hard. I believe it's not the right adapter because it isn't listed here http://docs.info.apple.com/article.html?artnum=16168 The computer works on AC power fine, it just won't charge the battery. It's possible that the battery is just old and won't hold a charge any more. I thought I'd post this problem here to see if any of you guys are using a Powerbook G3 with an M7332 adapter with no issues. Let me know. Thanks.
