As a follow-up... I stripped both Powerbooks to the point I had all the parts removed - except the logic board and stuff on the top side attached. I transplanted a working eject mechanism for a broken/bent one in the "good" one. I then moved the charging circuit, as the "good" one's was damaged. I left the PMU unit in place and swapped the entire case piece. I reassembled the "good" one, put the processor card from the bad one (see below why), put the keyboard back in, powered up and, success!!! No constant fan noise!.
The good one had a number of issues - probably why the fan was on constantly. It had no processor cover, so the fan was probably trying to compensate. Replacing that might have been enough, but gutting the machine allowed me to fix the battery eject and charging circuit. I'm so glad I did, because one of the two batteries charged fully and claims to have 2+ hours power! I booted on battery and it seems to be good. Even if it is lying, it shuld make the pram and clock retain info! Hopefully the PRAM battery is charging too. My only mistake? Ran the 10.3.9 combined update and now Panther refuses to boot :-( But that is an Xpostfacto issue. Orr possibly to do with memory. Did 10.3.9 tighten up memory chip requrements? I attempted to use a 512mb pc133 chip initially and 10.3.0 seemed to fail in the same way. It booted right away when I put back the original RAM. I can fiddle with all that later though :-) Matt --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to Low End Mac's G-Books list, a group for those using G3 iBooks and PowerBooks (we run a separate list for G4 'Books).
