Both my Macs used to slowly pulse their power lights when sleeping. My iBook still does, but my G4 now stays at a constant brightness much the same as during normal operation. Both are running 10.2.8.
Have I inadvertently changed a setting or is this an indication of hardware problems?

If the screen is black and the power light isn't pulsing, then the display is asleep but the computer is still awake. Check the Energy Saver settings, you've probably turned on the "separate time for display sleep" option.
For a quick test, use the "Sleep" command under the Apple menu, or press the power button briefly (no more than 1-2 seconds). The G4 should go to sleep immediately and the light should start pulsing.

I do briefly press the power button on my LCD display when I want to put the G4 to sleep. The display goes black, the G4 appears to shut down (no more fan sound) but the light does not pulse the way it used to.

OOPS. I was wrong. The lack of pulsing really does indicate that my G4 is not fully going to sleep, even when I select Sleep in the menu or touch the power button. The drives spin down and the display goes black, but the fan stays on (it's quiet enough that I didn't realize until I put my ear near it).
So now my revised question is -- what is keeping it from sleeping?

Update -- Sleep still works normally when I'm booted into 9.2.2., so the source of the problem is probably an OS X app or feature.
