G5 imac won't start - ever again. Update

2009-06-07 Thread Mike Murray

Hi muggers

Just to bring you up to date on my recent plea for help; my G5 iMac  
has been diagnosed with a logic board failure = a new imac. Gulp. So  
now we have a new 20 inch aluminium iMac.


That's the second G5 iMac we've totalled in less than a year. I'm an  
avid fan of things Mac but this seems to be taking built in  
obsolescence too far. Both machines were about 3 1/2 years old, both  
cooked the logic boards.


Only symptom...fans starting to fire up randomly; on reflection some  
components were obviously overheating.


Moral of the story; backup every day and expect failure if you're  
still running a G5 iMac.


Has anyone had success in pleading a case with Apple for some  
compensation?


Mournfully,
Mike

Previous email...

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

Can some one explain why the logic boards are failing in brand new iMacs
today. When looking for the upgrade to my G3  a few months back I was going
to buy a second hand G5 from ebay. There were heaps of iMacs out there going
for cheap ($50-$150) with this problem. Why? I've been put off gutting a G5
now... Very happy with my G4 however.

Re: G5 imac won't start - ever again. Update

2009-06-07 Thread Mike Murray
Roger, yes there was a program for fixing the first run G5s...it's now  
been suspended. This latest failure was a later model (with isight  
camera) and to my knowledge there's no such program.
 I believe the problem is not as common in the later models, but that  
might just be a function of age, i.e. we're now getting to the end-of- 
life stage!


Re symptoms:
The earlier G5 (that failed last year) had persistent problems of not  
waking up from sleep and odd power-related issues including very  
occasional fans running unexpectedly. Eventually it wouldn't wake up  
at all.


The later one with isight camera that failed last week had mysterious  
fan running issues for some months, usually when it was asleep and  
unattended. We'd go into the room in the morning and the fans would be  
roaring, no idea if they'd been going all night or started up when it  
heard us approach!


Tom, if the fans are running hot I would say it's on its way out.  
Maybe in 3 months, maybe in the next few minutes.


Warwick, based on my limited experience (2 failures out of 2) I would  
recommend not buying a second hand G5 iMac. We still have a Tibook  
(400 G4) and a G3 slot-loading iMac, merrily continuing their happy  
lives without a hitch. And now two very recent iMacs (and a couple of  
reliable Macbooks). We've had various macs over many years and never  
really had a problem (although on thinking about it there was a dog of  
a powerbook with a screen problem that took some sorting out).


As someone said recently, things break.

Backup is the key.

Cheers
Mike

Hi Mike

I also had a newer G5 at the office that had the same issue as yours and it was
just out of the 3 year applecare warranty, I have asked Apple for an extension
and am waiting to hear if they will cover it!

I personally would never buy a G5 iMac but go for one of the newer intel ones
instead.

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:

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.

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:

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
