[Ham-Mac] sleep

[Kerin Tyrrell]

For what it's worth if this applies to you, I had this problem with my mirror-drive dual G4. Long story short, third party USB cards or hubs usually cause this problem. Found advice on the web, but turns out this is an Apple documented issue. (Don't know what they expect you to do when they don't sell the cards themselves, eh?) AND, not only did it not sleep, under Jaguar I had to reset the PMU (G5s have a SMU) and live with never sleep. I have the other web link somewhere at home (I am away). I tried sleep again when I upgraded to Tiger and as I recall it wasn't as bad but still didn't work right, I'm sorry I can't recall what was the problem. Anyway, you might try eliminating third party USB cards or hubs to see if it sleeps.
Best of luck!
