Hi all,

Just to let you know I put in the replacement power supply and it clicked nicely on power cord connection, but there was no more activity from the G5 whatever I did.

Inserting the startup disk in my QS I scanned the logs and found a series of complaints about cpu 1 so I decided to let it go and look for a later model to replace it - I'm thinking imac now I have found they can run two screens.

Thanks for all your help and to the list in general - it has been very useful getting me over problems over the years.

Kind regards

Ged

No click-THAT sounds like a dead power supply, prior to that you were likely running an capacitor juice, now it is all discharged. I agree with Kris re: the diagnostic. It is repairable, but not fun doing so - first locate a good, used PSU (from any source), then steel yourself for a good afternoon's work on tear down and reassemble. IIRC, it IS feasible to run the G5 in a sort of "pre-assemble" mode (supply and motherboard, etc.in proximity of tis destination but not affixed).
Best of luck to you,
Dana

Hi all,

I've tried all the options from the friends on this list but no joy.

However, after a good clean out of dust bunnies and re-seating everything re-seatable,, I noticed that when I plugged in the power cord the mac did not "click".

I'm sure it always did that previously - is that the hint I'm looking for ?

Has anyone connected this non-action with a resolution, or even a "no go"/"give up" result?

Have you reset the CUDA switch with all cables unplugged including the power cord?

Help

Power mac G5 1.8DP Tiger 10.4.11 all updates in place

This morning...

Woke it up, collected emails, deleted three, mouse froze, pulled it out plugged it in, no joy, checked keyboard, nothing happening!

Force shut down, restarted, chime, low fan noise, no display (2x17" ADC, one via apples power gadget into DVI).

Force shut down, restarted, held down T for Target Disc Mode, one chime, no sign of drives on firewire connected G4.
Tried this several times including with display card removed *.

Force shut down, restarted, Cmmd+Opt+P+R, only one chime, no further action.

Could this be caused by a duff display card - see *?

I moved the startup drive to the G4 with an ide/sata adapter and am working off it now so not a drive problem.

What is more likely to be the problem?

What does anyone think I should try to do to resolve the problem before looking for a replacement?

Regards to all

Ged
