Sleeping iMacs

in Genius Bar edited January 2014
Hey, my iMac, which came pre-installed with jaguar has some sleeping problems. Éverytime that the computer goes to sleep when i move the mouse again/hit enter it gives me a message that says that i need to restart and how to restart my computer. nothing else. So i turned off the going to sleep function for the computer, and left the monitor to go to sleep. But i sorta wanna be able to put my computer to sleep, because everyone here says that one should not turn off and turn on your computer each day(why???) so i wanna preserve energy, because i guess i'm just leaving my computer on all the time 'awake' any advice would be welcome. thanks in advance. . . .

    You might be experiencing a kernel panic upon waking up. Is the message you see presented in several languages in a window similar to this?

    It's probably not *identical* to this screen, because this is from a really old build of 10.2, but should look similar.

    Anyhow, a kernel panic is actually a system crash at the lowest possible level (the kernel). That's why it absolutely requires a restart. Unfortunately, it's sometimes very difficult to trace the cause of these problems. I have read similar reports of Macs "panicking" upon wake up, but I haven't seen a unifying solution to them all.

    What you might want to try is this. Insert your 10.2 Install CD and restart your Mac holding the 'c' key. That will force it to boot off of the CD. Once at the installer screen, choose Disk Utility from the Installer menu. Select your hard drive from the list, click the First Aid tab, and click the Repair Disk button. This will attempt to correct any errors that may be on your drive. When that's finished, you might should also click the Repair Disk Permissions just to be safe. Once everything is finished, Quit Disk Utility and then Quit the Installer and it'll tell you to reboot.

    Hopefully this will help some. <img src="graemlins/hmmm.gif" border="0" alt="[Hmmm]" />

    Oh, by the way, here's the answer to your question about sleep vs. shut down. If your computer starts up quickly from being completely shut down, do feel free to just shut down when finished. The only reason people advocate sleep is because it's just usually faster to start up from sleep rather than a cold reboot. When sleeping, your computer uses almost as little power as when it's shut down. In your case, though, if you have to completely restart after sleeping anyway, you'd probably be better off just shutting down when finished.

    Yes, Brad, the picture looks almost the same. now, i'm a bit of a wimp when it comes to installing operating systems and tinkering with my computer more that I know how to do. if i follow the instructions that you gave does the repair disk stuff, i won't need to re-install the programs i have on or lose e-mail or any files right? thank you

    That's right, no need to worry about reinstalling anything right now.

    The disk repair from the CD is a pretty straightforward procedure. It's basically just click and wait.

    If you have any other questions, please don't hesitate to ask. Heck, even I remember the onset of anxiety from when I first started tinkering with fixing Mac OS X some time ago. Hey, we all gotta start somewhere!

    did what you said, got confused and scared, but then heroicly over came my fears and checked my drive for problems. Verdict: Drive Kivo, has nothing to be repaired. maybe it will sleep properly now, maybe not. YAR, I feel as if i'm on my way to being a mac os x guru like brad now! not.. . . at least i can put the os install disk in the computer without worring though.

    edit=my text got smilyized
