In your troubleshooting, did you happen to reset the PMU? It controls the sleep functions. Just a thought. PowerBook G3 Series (M4753) 1. If the computer is on, turn it off. 2. Simultaneously press Shift-Fn (function)-Ctrl (control)-Power. 3. Wait 5 seconds. 4. Press the Power button to restart the PowerBook computer. A hard reset might work if this doesn't. Remove the battery, then hold down the power button for 30 seconds. Wait five seconds. Replace the battery and push the power button.
