Thanks for the advice Philippe

Further research indicates that 'there are no user serviceable parts in this model' and the back doesn't come off readily. The link you gave is for the earlier G5 imacs.

So today's job is to find an Apple repairer and await the diagnosis...which I fear may be grim.

Mike

See how many other people have had trouble with a G5 iMac

Hi Mike,

Wonder if it is your motherboard battery that has gone flat. I know
that if this battery goes the machine may not boot at all.

Can you remember if your date and time was being kept accurately last
time the machine booted? If you have had to reset the time and date a
few times this would indicate the RAM battery going flat.

Sorry can't help you with opening the iMac, I have no experience with
this particular model but go to the following Apple link for
instructions:

Best of luck,

Hi all

Our sole remaining G5 iMac in the fleet has decided to play up.

This morning when trying to wake it up as normal the screen remained black and the fans started to roar. Held the off switch down for 5 seconds and it shut down. left it for a while, unplugged everything, switched it on. The light came on, very slightly pulsing, but no chime. Dark screen. After about a minute the fans came on again, so shut it down again. Repeated the process
a couple of times.

Thinking there may be a dust build up inside I tried to get the back off, loosened the three screws, but couldn't get the back off...seems very tight
and I didn't want to wriggle it too much.

Opinions sought. Is there an easy solution that I'm overlooking?

Cheers
Mike
