If I put my iMAC to "Sleep", it may not "wake-up" when I hit a key. It is necessary to turn of the main power and do a full restart. This has happened with both OS*.6 and OS 9.0.4

Which iMac do you have?

This same problem happens on my G4. The operating system is OS 8.6. What is the problem?

Same for me running 9.04 on a b/w G3. When I wake up, the screen appears, but the HD is frozen. Happens whether I manually put it to sleep, or let the energy cdev do it for me after 30 minutes. No one seems to have an answer (other than backwards migration to 8.6). Hope X does the trick... I expect my beta tomorrow......... (gulp!)

Try using the control strip at the bottom of your desktop to put your Imac to sleep. (If it is hidden click on the little tab at the bottom, left, and it will pop out so you can use it). First, I click on the picture of the telephone pole to disconnect. After it reads displays the word idle, click on the picture of the moon at night to put it to sleep. Works for me! ONLY way it works for me!
