I have more information on my sleep problem on my G4 running 10.4.9.
I try putting my computer to sleep in the following ways.
1. I select Sleep from the Apple menu.
2. I press the Power button momentarily on the front of the Mac.
3. From the log-in window during startup, I press the back arrow and select
Sleep
In every case, the cursor disappears, the keyboard stops functioning.
It kind of sounds like, with the exception of your screen, the computer is going at least partially to sleep.
Which particular model G4 do you have?
Does your G4 have a light on the front that glows brighter and dimmer in a cycle (simulating the slow breathing of someone asleep) when the computer is sleeping?
I have to reboot in order to get going again.
Next time, instead of rebooting, try simply pressing the Space bar on your keyboard, and see if the computer wakes up again.
My optical mouse stays lit.
That's very peculiar - it should go dark when the computer is asleep.
If I let the Energy Saver kick in, the screen goes dark. Waking up from that
state seems to work OK.
I have booted from a version of 10.3 on a different drive. The same problem
occurs.
I have used Disk Warrior and other techniques to purge my drives of errors.
I now get a clean bill of health. I have reinstalled 10.4.9. Nothing helps.
I will try removing everything from my startup folder.
I cannot see how reformatting my main drive and reinstalling the system will
help under these circumstances. Can it be a hardware failure somewhere?
What now?
You never answered regarding my earlier suggestions:
1. Have you taken a look at your console and system logs to see if any error messages are generated when you put the machine to sleep? Open /Applications/Utilities/Console, then from the Console menu bar, select File > Open Console Log and File > Open System Log. Then put the machine to sleep and see if you see any error messages in the logs.
2. You cannot wake it up by pressing the space bar?
Also, have you tried resetting the power management unit (PMU) by following Apple's instructions?:
