Dead PowerMac G4 Digital Audio Model

2009-02-26 Thread BillBoggs

Worked flawlessly for many years. Now, without any warning, it just
stopped. Won't power up at all, no sign of life whatsoever. Any
suggestions where to start?
Thanks!
Bill

Is it plugged in? Is it plugged all the way in? Did a cat step on the  
power strip it's plugged into?

(Don't laugh, I'm not being patronizing, each and every one of these  
is something that's happened to me ;-)

Some Macs, and I don't know if the DA is one, will act like this when  
the mobo battery gets too low.

I will start with checking the power supply. Got a multi-meter?

Maybe a Circuit Breaker is off in your home's electrical box?

Maybe a power strip needs resetting? replacement? Try another one, in  
another wall outlet?

Here's instruction on how to replace the psu ... not that that is the  
problem, just might be of interest:

Greetings ( + )!( + )

The easiest way to check an A/C power source is to plug a lamp into
the place where the mac is plugged. Not the same power strip but the
same socket.

My first though here is a dead pram battery. If you can't get an  
official exact match, a 1/2 AA will barely fit and work fine.

I'd try the following hardware tests in this order (from least costly
to most costly):

1. PRAM Battery
2. Power Supply
3. Processor

As others have said, double-check all your connections/power plugs.

Another thing to check is the voltage specifier on the powersupply,
(little red switch next to where the cord goes in) it might have
gotten set to 230 instead of 115. And then just try the usual,
different outlet/power cord. If none of that, I would guess it's the
power supply.
