This is a classic WS flaw. Remove the main battery and let the machine sit for a couple of days. Then install the battery and connect the ac adapter/charger and attempt to do a power manager reset, followed by a reset. It will probably work. Then the cycle will probably repeat in a couple of days. A new PMU will often cure this. I have a 300 MHz WS-II with maxed-out RAM, and it will go through PMUs rather regularly. A sign of this is the machine saying "flup, flup, flup, ..." whenever a PMU reset is attempted. A possible cure is backing off to 256 MB (from 512 MB). Funny thing is my two 233 MHz WS-IIs don't have this problem. I think it is perhaps that the 300 MHz CPU card takes so much more power than does the 233 MHz card that there is too little capacity in the WS-II's power system left to power a full 512 MB. Anyway, I've put three PMUs in that 300 MHz machine, to none in the 233 MHz ones, and the 233 MHz machines are the only ones I feel are reliable enough to travel with. As a matter of fact, on my next road trip, my main machine will be a Kanga (modified to support Cardbus) and by backup will be one of the 233 MHz WS-IIs. I have brand new batteries (Apple) for each, and the same 45 watt ac adapter/charger works for both. -- PowerBooks is sponsored by <http://lowendmac.com/> and...
