G4 733 D/A , 10.4.11. This morning there was a few second power failure according to my wife. Ther G4 shut down from the power failure. I didn't have "restart after power failure" selected in the Energy Saver prefs. I restarted the G4 when zi got home and after I was done with it, selected SLEEP from the menu. The G4 wouldn't respond to sleep. I logged out and tried SLEEP from another user acc't and from the login screen. I then went into the Energy Saver prefs, made sure everything was as I wanted ( 5 min display sleep, 10 min HD sleep, and "put disk to sleep whenever possible". I then rebooted and sleep still wouldn't function. Suggestions please. The G4 is on an Airport Extreme network which functions normally.

Thinking about the problem, I deducted that perhaps some internal system settings got screwed up from the brief power outage and possible surge on power being brought back on. I zapped the PRAM and did a power management reset and now all is well again.
