Hi Susan,
Yes, the G5s are well known for having sleep issues.
I've had another thought (yep, I have them occasionally). Try going
into System Preferences > Security > Firewall - click Advanced and
turn OFF (take the tick out) Enable Firewall logging.
See if your G5 will sleep now.
Cheers,
Ronni

Hi Mike, I do think the problem has been around so long that its not
the first sign of a major problem. This model of Mac did have major
issues at first, which were fixed by a long time coming firmware
update, back in 2005. cheers, Susan.

Hi Susan
Hate to add a sour note, but I've recently replaced a 3+ year old
20-in G5 iMac with a cooked motherboard. The first symptoms were
odd behaviour with sleep patterns and mysterious awakenings and
shut-downs. Apparently this is a known issue.
The new 24-in is great.
Cheers
Mike

Hi all, the problem with all of this diagnostic stuff is that I
have had, and still have, other Macs, which are connected to
networks, printers and external hard drives. All of my other Macs
go to sleep when I'm not using them, unless I have something
obvious happening, such as a file downloading.
This is unique to this computer - in my case a G5 1.8 SP, and I
know its unique because of using a wide range of Macs. I can live
with it, but thought it useful to share with Severin that this it
might just be a quirk on these computers. If we could solve it,
that would be great!
cheers, Susan.

Hi Severin,
Some programmes perform periodic activity which (intentionally or
not)
will restart your Mac's time-to-sleep timer. For example,
downloading
a large file will prevent your disk from going to sleep and thus
prevent your computer from going to sleep. Continuous file
sharing and
internet chat logging can have this effect also, despite the fact
that
you have walked away from your computer. Severin, if you close all
your apps and leave the computer for 10 mins, does it go to
sleep? I
imagine it won't, but if it DOES, then you should try to identify
which programme is the culprit.
