iMacDV won't sleep

[Snusmumriken]

My olde imac won't go to sleep voluntarily. Nor does the drive ever spin down (except when I tell the mac to sleep).
I blamed pmu battery (that has been dead for a long time but since I installed OSX the mac has not complained about it.)
Now I put in a new battery and pressed the "reset PMU" button according to instructions, and expected the problems to disappear, but I decieved myself. Nothing changed.
I need the automatic sleep or hard disk sleep to function.

To continue this debate with myself I will add that once the described battery replacement was done. The OS9 sleep functions were reactivated. Didn't think to check it at once. So no weird hardware issue I assume. Now what is installed that keeps it from sleeping. If I could find it it sure would help all those unsuccessful in keeping their macs from sleeping or spinning down. Maybe it's an old QTSS that I installed ages ago. Will investigate.
