I've got a Powermac G4 FW800 1.0GHz running MacosX 10.4.8.

The Mac goes to sleep (but can still here fan running) OK but I can't wake
it up. I looked on the Apple support site and the only problem relating to
this that I can find refers to the Radeon 9000 graphics card. My machine
is fitted with a Geforce64 card.

Does anyone know why my Mac won't wake up?

Then it's not going to sleep. At least as far back as the Sawtooth a
sleeping Mac is completely silent.

So my guess might be that this is related to whatever's preventing it
from sleeping in the first place.

Any messages in the console.log (viewable via
/Applications/Utilities/Console.app) around the time you either attempt
to sleep or attempt to wake up?

The best intentions in the world don't make a flawed argument magically valid.

As Greg said, it isn't actually going to sleep unless the fans stop and
you see the power light start pulsing.

Do you have a USB 2.0 card installed? Are there any devices attached to
that card?

It's been my experience (with my dual 1GHz QuickSilver-2002 PMG4) that
USB 2.0 devices prevent sleep. I have a Belkin card in my system, which
works perfectly, but I can't put it to sleep if anything (even a hub) is
attached to one of its ports. Attempting to do so effectively crashes
the machine - I have to force a power-off in order to recover. If
no high-speed devices are attached to the card, the computer sleeps
fine.

For me, I don't care that much - I never put this machine to sleep
anyway (I just have it put the display to sleep when idle), but it is a
serious problem for those who do put their computers to sleep.

Unfortunately, I know of no fix for this. If this is the problem you
have, your choices are to either stop putting the computer to sleep, or
stop using your USB2 card (or disconnect all devices from it when you're
not actively using them.)

Macs with built-in USB 2.0 ports don't seem to have this problem.

Thanks for your advice - I also have a Belkin USB 2.0 card installed and
there are devices connected to it. I'll just have to forget about putting
the Mac to sleep.
