Re:1.42 Power Mac G4 - 2009/09/22 16:25The PRAM battery seems to be the catch-all fix for everything posted on the Apple discussion groups.
Very interesting Krow.
The last three MDD machines I have looked at here in my retirement village have all had non-operating PRAM batteries. As I had a quantity on hand which are of no further use since going to a G5 Dual Core popped them in and anyway each one booted. Seems about five years is there limit.
Two were 1.25DP and one a 1.42DP. Wonder if the DP has anything to do with this? Have never seen the same problem with a Quicksilver, D.A. or earlier. Seems to be something the MDD do exclusively.
For some reason they will not boot either when the battery is flat.

Re:1.42 Power Mac G4 - 2009/10/04 06:57Harry,
My 1.25 DP works fine with a dead battery. Every time the power goes out (often) it boots with the date/time error message. Maybe my battery still has a little juice in it, I never tested it but the machine boots every day with no problems.
Who knows..these things don't always make sense to me ;)

Good to hear you got it up and running again. I keep my fingers crossed that my PSU keeps working on my MDD and if it does die it will be time to part the G4 out and upgrade to a G5.
It's this kinda stuff that makes me appreciate my old PowerComputing clone that uses a standard ATX PSU. And that old clone is still working to this day running all the original components except for the hard drive and CD-ROM. At one time the clone makers did Macs better than Apple did. You would think Apple had learned something more than just not licensing the OS from the experience.
