I use my G5 for work and it would be awful to have it fail right in the middle of a job. Why do I have to wait for it to fail before I can get it fixed?

My PowerMac falls in these serials numbers and I have not had any known direct problems with the power supply but I have had alot of problems with the fans rev'ing loud and the system hanging. Might be related?

This is a pain in the butt in a major way though, as I rely on my baby daily for school related work during the weekdays, client work on weekends and holidays....and the apple store is a 45 minute commute with no traffic :(

I have the dualcore 2 GHz with the serial number listed. I had to send it in for a service to replace the power supply. Since it was under a warranty, I didn't have to pay for it. This happened 3 month after I purchased the computer. I had the computer for one year now and it's running fine.

I have the same problem. I did notice something interesting though: tilt the machine at a 45 degree angle and the fans go loud. Tilt it again the other way and they go quiet. Weird.

My machine is one of the early serial numbers. I haven't experienced any of the above problems, but my iMac does have another problem. It shuts down instead of going to sleep. Another message board hinted this might also be covered under this program. Anyone else heard this?

I bought my G5 in July of 2005 but had the power supply replaced under warranty in May of this year. A week ago I came home to find it dead, exactly as described. So my G5's serial number doesn't fall within the range but the power supply is from the bad bunch. Anybody want to guess how much time I'll have to spend with Apple on the phone trying to get them to cover the repair?

Huh, Mine falls in the RM4... area which isn't covered.

However, I do have weird power issues. Sometime the power goes out while it's on. I come home to find it asleep/dead sort of but the fans are blasting full speed. If I shut it down and try to start up it won't turn on. Eventually on the 5th or greater try, it finally starts up.
Very annoying. It is plugged into a surge protecter, but I think I'll just get a battery backup UPS.

My Powermac falls in the range of serial numbers, I have had no problems with it whatsoever since I bought it in Jan 06.

I bought my PowerMac G5 earlier than that, but it had major problems with the power supply. It would send spikes to components, notably the hard drives.

I have had to replace no less than 5 drives (terabytes of space) and after an encredibly (unnecessarily) protracted back and forth between me and Apple they refunded me late last year.

It didn't turn me off Apple for good (though it very nearly did) and now I have an 20" Intel iMac with which I'm very happy).

Didn't PM models even earlier than that have wheezing and whirring problems? Hmmmm...

And still they do nothing about the Powerbook power supplies that regularly catch fire. Sigh.

my serial starts with CK552... so it's in the range...however no problems over here a all. it's a very fine machine and i'll keep it despite the fact i have recently ordered a 2.33 GHz Merom MBP.

My dual-G5 has been exhibiting serious, apparently power-related, problems for the past couple of weeks but the serial number (CK429*) doesn't fall within the specified ranges. Most times it'll get to the startup chime then no further, and it isn't feeding power to the USB ports (no LED activity on the keyboard/mouse).
If they don't extend the serial ranges I'll have to use the machine as a doorstop.

I had to go through this last February. It was a nightmare, I came home from work, and my computer was off. I assumed that we lost power at the apartment and the back-up shut it down. I tried to turn it on and nothing happened. I called Apple they walked me through some things, nothing work. They told me it was either the power supply or logic board. So they decided to replace both. However, the power supply was on back order. So about 1 month later they finally had people come out and replace both the logic board and the power supply. And for my waiting so long they gave me an iPod, on the house. That was pretty sweet although I wasn't too happy about not having a computer for that long.

The 2.3 G5 DP that I bought in May 2005 started to shutdown everytime I launched iTunes and only when I launched iTunes, I tried everything, it went to the shop where they played with it for 3 weeks, finally it was tracked down to the power supply, that was a year ago, after it was swapped out no problems......yet!

Mine falls within...but no major problems ever. The only thing I've had happen is some hangups with an old fw audio device. My current one has never caused issues like that.

I don't know what to do...

Had my G5 for about a year and a half, the power supply failed two weeks ago.

Was instantly diagnosed as such by AppleCare via telephone. Took about 48hrs in repair at the local Apple store.

I believe I was one of the first to experience these issues. Had on-site applecare techs who made 5 trips to my house trying to figure out the issue. With no luck fixing it, 2 months later I ended up getting a brand new machine, oh and the mac pro just did get released at this time so I spent a few hundred more dollars and now have a Quad 3.0 out of it!

I was sad to see my beloved dual g5 go, but i haven't looked back since.

Hopefully, others do not experience the 2 month long tech issue I encountered. Glad to see they've finally figured out the problem.

I just sent one in for repairs - it took 2 days, including the time to get the parts from Apple. The techs at the store mentioned somethng about Apple being supplied incorrect parts when they built the machines. It appears as though the machine was slowly overheating itself. Mine exhibited random shutdowns, then upon restart (or sometimes a fresh start) the machine would exhibit what appeared to be a bad video signal. Sometimes it would make it to startup and get the desktop, other times, not so far.

Once I got the machine back from the store I noticed the Serial number listed in "About This Mac" was really different. Starting out "cccc10000" Odd. I assume Apple now has a record of this.

Another note, even though I had AppleCare on the machine, it was not "used" since this fell under the G5 Repair Extension program. As such I had to bring the machine into the store to have it serviced and they would not "use" my Applecare...

My dual processor 2.3 GHz G5 has been shutting down randomly and failing to start up since before the warranty ended, and my attempts to get Apple to fix the problem 1 month after the warranty expired were futile. NOW.........they acknowledge that there is a problem (finally) BUT exclude my unit as being out of the affected range of serial numbers!!!!! I just can't believe it. I had the very same treatment occur on 2 iBooks I purchased. Apple just stone-walled it and never admitted a problem with these either. I know because I owned not one but two of them!! If this were a game of baseball, Apple has 3 strikes based on the 3 machines I have purchased........
