This PowerMAC G5 is so frustrating!

[Zeke D]

First it wouldn't power on after sleeping, so I disabled sleep.
Then it had issues with 2 out of the 4 GB of RAM, so I removed 2GB.
The Radeon 9800 was giving me artifacts, so I swapped it out with a 9600XT.

Now, after sitting all night powered sown, it takes all sort of shenanigans to get it to boot. Sometimes just pressing and holding the power button will allow it to restart. Sometimes I have to unplug it from the power source and it will power on after 10 - 15 seconds. Sometimes pulling the side panel and baffle seem to make it work. When this is going down, the front indicator stays off until the power button is held to shut the unit down. Some times it chimes sometimes it doesn't.

Once it has booted, it is just fine if I shut it down and start it back up. The front indicator turns on before the chime and everything is cool.

The battery was replaced a month ago, and all software is up to date. I have run Monolingual to get rid of other languages and architecture. No bluetooth or wireless is installed. It seemed to work without issue for about 2 or 3 weeks, now this. Any suggestions?

Maybe you have a bad logicboard or power supply.

 

[Lil Chillbil]

has it been exposed to a power shortage of some kind, that would be my guess. It could be any number of items wrong with it quite frankly

 

[Zeke D]

I guess I will try swapping out the power supply with the one out of my dead DP 1.8Ghz. That one suffers from the bad solder joints on the ram slots. The problem is I need to wait overnight to test it. I don't think I can put the 1.8s in the 2.0 board.

 

[Orange Furball]

Sounds like either a power supply or logic board. Is the power supply from your 1.8 powerful enough for the other one?

I expect the PSU is the same in both units. My son should be home in the next hour or so. (he holds the light, fetches my tools, etc.)

 

[Nameci]

have you done an SMU/PMU reset?

 

[Orange Furball]

Oooooh, snap! Now you've done it. You have incurred the wrath of Lil Chillbil.

It should be. I think I've seen 450w and 600w ones (my 2.0ghz had a 600w) and I'm not sure what the 1.8Ghz uses.

And Wikipedia isn't always right or accepted by professors.

 

[Zeke D]

Don't worry, consider it done before you have thought of it.

Back to topic, reseat your battery. Check if it is seated properly.

The battery is snug in it's holder.

I had that same issue with my DP 1.42 G4 before. I took the battery out and reseat it back. Rebooted and it work fine from that time onwards.

I should be able to use the psu out of the dead dp1.8 right?

Just check the wattage on them both first. It should look like this

Just look at the max output

Did you already post about the demise of your G5?

I can not be sure, I have never done a psu transplant with a G5 yet.

 

[PowerPCMacMan]

Whoa.. calm down there buddy, there's no need for threats to others here. The Power Mac G5 is still a neato machine, though it does have its problems as others here have mentioned, but there is no reason to cause problems.

try buying a decent computer

Power supply issue. Im having the same issue some time ago, replaced PSU and problem solved.

Yes. But I don't want him to take apart his whole his the computer and switch the power supplies just to find out the thing wasn't powerful enough

 

[PowerPCMacMan]

Out of curiosity, is it possible at all to take out the lower rated power supply and put in, say the power supply unit from a dual core G5? Those are 1000 watts versus the older ones.

Yes. The power supply will only output what is necessary. But if a computer comes with a 600w power supply it may use 450w regularly, so a 400w wouldn't work. But if you stuck a 1000w in it would only use 450w still. That's why it says XXXw MAX output. This is the same with all desktops.

Its like ram, if you have to little you'll bottleneck your system. So its best to have more than necessary. So if you go over your normal amount, you have some head room

 

[Zeke D]

I didn't see your post amongst all the trolling. I haven't done a sum/pmu reset todAy, but it has been done while the unit has been symptomatic.

Here is the one out of the dual 1.8. I am gonna swap and see what happens.

That will probably work just fine

 

[Zeke D]

The psu swap is done. So far sleep appears to be working. I put the other gig of ram back in. I thought I had 4gb, but a set of rm is pc2700. I will eed to look around and locate that last gig!

This is true for the 450W and 600w, but with the Late2005's 710W and 1KW they have different connector plugs so they wont fit on the logic board thats not late 2005, but yeah if yours has a 450w you can use a 600w instead it wont fry anything.
