I recently installed 10.3 (was 10.2~) on G4 duel. ONLY since the upgrade, every now and again, without any recognizable regularity, when I either hit the power button (quickly for sleep mode) or select sleep from the apple menu my mac refuses to go there. I have a sleep/screensaver login enabled and I must cancel until I win the war of wills. This does not follow any logic as I have removed/added the USB & firewire devices (per apple's recommendation) in an attempt to isolate it. At the present time it responds flawlessly, yet it has previously acted similarly before my intervention attempts. My impression is that someone/thing is active via my dsl connection, I recently restarted the dsl modem too. Any suggestions?

I think I may have solve the sleep problem after tinkering with Sleep panel. But I'm not sure if that would fix your sleep needs for your Mac. Anyway, here's what I found out. When the computer sleep is set to Never and display is set to sleep for some set time, and that may include harddisk with an on-line connection(mine's dial-up); you select Sleep from Apple menu, the whole garbage disposal dumps your system off the on-line connection. The problem solver is to click the option button in the Sleep panel and click on the check box to uncheck the "Allow power button to sleep computer". This choice in the option setting keeps the on-line connection going with the sleep settings. You could go a step further by trying your sleep settings for Display and hard disk, but I would set the computer sleep no less than "Never". Good luck!!!! /forums/ubbthreads/images/graemlins/tongue.gif

I am having a similar problem. There is a preference file in the root that controls sleep. I think deleting this file is the fix. I'm a little hesitant to simply log on as root and find and delete the preference file (I don't even know its name). I thought I saw this discussed in an old MacWorld but I can't find the article. Maybe someone can help us both.
