Sleep/Wakeup problems?

Message #1 - Posted 2007/04/20 - Salmon Egg

I am using a late G4 desktop running 10.4.9. It happens in several ways.

One way is that I put my computer to sleep pressing the power button once (It is set up to do so). I hear a click from the computer (relay?) as if it goes to sleep, but the screen stays illuminated. My cursor disappears. I cannot wake up the computer by pressing a key.

I will try something else, but I want to send this cry for help first.

I am thinking that I might have to reinstall the system because some files got damaged.

I have reinstalled system essentials. That has not alleviated my problem. Putting the computer to sleep removes my cursor, leaves the monitor on, and disconnects the keyboard. Earlier, I should have mentioned that my optical mouse, which appears to use a red LED or laser, goes out.

I have found that if I wait long enough for the energy saver kicks in, my screen does go black, and the computer wakes up if I press any key. The mouse does not go black.

This is beginning to drive me crazy.

That's likely the hard drive head parking itself.

but the screen stays illuminated.

This may indicate a problem with the video driver or card.

My cursor disappears. I cannot wake up the computer by pressing a key.

You cannot wake it up by pressing the space bar?

Just to clarify, when you say it "leaves the monitor on", do you mean that:

a) you can still see the menu bar, the icons on your desktop, etc. -or-
b) the image is blackened but the monitor's power light is still on

I have found that if I wait long enough for the energy saver kicks in, my screen does go black, and the computer wakes up if I press any key. The mouse does not go black.

This kind-of sounds more like the screen saver is running but the computer is not actually asleep. What is your screen saver set to in System Preferences > Desktop & Screen Saver?

I see the full display with everything except the cursor.

I just set the screen saver to never start but do not have data on behavior yet. If what you say is true, stopping the screen saver from turning on seems like a good diagnostic step.

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.
