Deep Sleep Regained

My two-week-old G4 suddenly developed the no-deep-sleep syndrome, where it would sleep the screen and the disk, but not the processor, when left for the (default) 30-minute period. It would go into deep sleep OK when selected by either the power button, or the Special>Sleep menu.

It seemed to do this of its own volition, without any reason I can think of. Anyway, I have fixed it! After trying all the usual remedies, to no avail, I finally looked at the Sound Control Panel. There, I found that the Input setting was Internal Modem. Don't know why. I set it to None, after which the G4 was fine. Deep sleep came automatically after the 30-minute wait.

Now if I could only figure out the rattle...

Hmmm. Perhaps that explains why I can no longer hear my modem dial. My Sound CP is version 8.5.1 and has an input selection only for <cd>, none for <internal modem>. Has Apple done this as a fix for the <sleep> problem? What version is your Sound CP? Burt

I don't know if this works but the setting reverts back to Internal Modem whenever the modem is used.

Sorry for being so quick. It reverts back to none after the modem hangs up. My iMac does sleep now.
