Is it possible to install it? What type of SSD should I find? Are there different types in the market?

⟐ Commented April 03, 2020 at 10:01 MST

This is what I have tried:

• replace with other RAM
• unplug drives
• Reset nvram like in this article. The problem is then that I have problems getting to OpenFirmware. Sometimes I am able to but when I get to the OF screen there is no reaction from typing. I can i.ex. type the first line but then there is no response from the keyboard. The keyboard is plugged directly into the USB port.

I got hold of the Apple Service Source Manual for Quad G5. (Let me know if someone needs that!) and just getting to the cooling and the power supply seems a bit tricky. So I read about this Apple power supply exchange (http://www.apple.com/support/powermac/po...) and am trying for that first. So it seems from the LED light that the CPUs are overheated and that could be related to the power supply going bad. I will post results of my shot at Apple.

• UPDATE - THINK I MAY GIVE UP **

I took the machine to an Apple service center and they confirmed it was the processors gone bad. Of course this has to do with the cooling failed. Still I was not able to get a warranty repair even if I showed them the extended powersupply article and the article about the cooland leak. They said the machine was too old. They did offer me to fix the machine for about $1300. Since this is 2 machines with same error and since I have 16GB of RAM invested in each one just before this all happened, I might just have to accept the offer. Any comments?

Any suggestions?

Still not resolved. The machine is a 2.0GHz dual tower model, late 2005. I can remove the inner cover and the red light goes on. Tried resetting both PRAM and SMU but still no luck. Earlier in the week, I was able to reboot it but if I turned it off, it wouldn't go back on again. Tried new power cable and different outlet but same thing.

Sounds like the power supply. Where can I buy one for this model? Are there any disassembly guides on iFixit to help?

This is a hand down computer that has been sitting idle for months (maybe even a year) now. Not sure if that is the issue. Any help is appreciated.

Thanks!

I have several units I would like to repair. I know they can be sent off for repair. Any ideas?

The answer to my question is yes. I bought a dual 2 GHz AGP G5 due to intermittent power issues, so i swapped out the 600W ACBel PSU for my Liteon 600W PSU and i ran the dual 2 GHz cpu's for a couple of weeks. Then today i swapped out the 2 GHz cpu's with the 2.5 GHz AGP cpu's and attached them to the heatsinks with new Arctic Silver 5 compound, and ran the 2.5.8 AHD disc and the thermal calibration passed. Now i have a dual 2.5 GHz AGP G5 running on air so no more LCS units for me!!!

Using Temperature monitor, my cpu's idle around 47 to 50ºC. If it goes over 65ºC then i hear the fans slightly. Then it drops back to idle.

I get the following Msg:

The Finder cannot complete the operation because some data in "afp://10.0.1.4/" could not be read or written.

(Error code -36)

Of course I have been over the sharing settings many times.

Anyone have any ideas?

I put in new ram (4GB DDR1) And then nothing. When i press the power button the white led does not stay on (And no blinking) No video, nothing. Putted the old ram back in, same problem. However i do get two sighs from the fans, and they ramp up to max after approx 10 ~ 15 mins. Also there is a red led right behind the top CPU? (cpu dead?)

Unplugged everything, tried resetting the logic board etc. still nothing.

Any ideas?

Thanks in advance,

Hello All,

Sorry for the prolonged silence since your very kind responses... pressure of work and domestic commitments have had to take priority.

We have reviewed all our options regarding the G5 and have decided for the time being to mothball the project until such a time as funds are available for a full-on upgrade to a modern machine... either a PC or MAC... that will fit the purpose and be more future-proof.

Thanks again for all your advice and assistance... we are very grateful.

So I've been trying to be "green" in the recent year, and needed an extra desktop. Picked up a 2.0GHz Dual Core (2005) and was told it booted to "?"

No such luck... got it home and it doesn't even light up the front switch (ie, no light, no sounds, nothing).

Problem Hierarchy (things to inspect in this order?)

- PRAM/SMU Battery

- Front bus switch

- Power Supply

- Logic Board

Is this correct? It's been awhile since I've worked on this model. Thanks

Jason

PS - I referenced this post, but want more info. Thanks!

Why won't my G5 boot?

⟐ Answer accepted June 12, 2010 at 14:51 MST

Power Mac G5 has been sitting on the shelf of a business for at least 3-4 years with no use or ever being powered up. I get it today and power it up but immediately the fans run high and theres no video on the screen. The power light blinks white twice constantly.

I took out all of the ram - same exact thing (and no beeps even).

I take out all the ram and pram battery - no change.

I held the pmu button - no change.

What am I probably looking at? May just need a new pram battery since it was sitting dormant for so long? logic board? psu?

any help is appreciated.
