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?

On my machines, if the fan is running the machine is not asleep. Is this a different kind of sleep? m.

Good point, what seems to be happening then is that the monitor display goes off. Moving the mouse or using the keyboard doesn't cause the monitor to display anything.

But is the computer responsive otherwise? What happens if you press Shift-Option-Command-Q, for example?

Of course if it's absolutely not responsive, you can just do a hardware shutdown / restart. m.

When that happens to me, I press the flashing button on the right-hand of the monitor which puts it to sleep. I then waken it up by pressing any key.
