As I said, apple care seems to think it's a PMU issue, so you might as well try their instructions for resetting that. I still don't know if the one time it got all hot and shut itself down is related to the other times that it just won't wake up from sleep. The last time it did this, as I said, it had been asleep, but then the sleep light went out and it wouldn't respond. I know I hadn't shut it down absentmindedly because it was making some noise. Weird. I still haven't called applecare again because it's working okay now, and I just don't have the time- maybe this weekend.... Anyway, good luck ccr. Oh, by the way, I've also noticed that sometimes the ibook gets confused when the screen is closed part way, but then space bar is pushed. It'll wake up, then go to sleep when the screen is fully opened. I guess that's to be expected with any laptop set to sleep when closed, but still, I wonder if there's more to it.
 
Okay, now this is starting to get annoying. It just did it again- I closed the clamshell and when I opened it five minutes later, I noticed the sleep light was out and I had to restart. I'm definitely calling apple care, but I wanted to post this as a record.
 
i dont have an answer for you. but i had a simular problem, you may get somthing usefull out of this:
i started using a program called sleepless. its used to keep the computer awake when the lid is closed. i would wake up the computer and it would be vary hot and still apear to be asleep. hiting keys and stuff didnt do sh... so i would reboot. and it would be fine. i farly quickly stoped using sleepless, but i kept it around for just in case. what i reallized was that, when opening the screen i thought it was still sleeping, in fact just the display was asleep but the computer was, and had been, awake. it would get really hot cause with the lid closed no heat could escape.
the reason why they dont give you an option to close the lid without putting the machine to sleep is cause it would overheat. also you could bang the working disc around wile travelling and screw it up along with your data.
so i imagine your having the same prob, differnt reason.
i would just not shut your lid till you get it resolved. or bang it around as much as you might, thinking it were asleep.
i would say, to test if this is the case, to run a dvd or somthing and see if its progressed after you open it back up. but obviosly that wouldnt work if you have no display. though the time when it seems to be fine. it is probably not asleep when you open it and thats why it apears to be onely an a occasional problem. so try it.
 
I believe I've heard of this problem

Your iBook is possessed!!! :eek:

No seriously, I think it's a battery problem. ( If it's new and you haven't already done this) Let it charge to full, then drain it back and charge again. ( It let's the computer know the full levels, and thus how much battery power is left) Then try using your computer again.

Is posession covered by apple care? :D

As for the battery, I did fully charge then fully drain the first few times, but what the heck, I'll try again!

Oh, and I'm sure it really is asleep when I close the lid cause the pulsating light comes on- it just isn't there when I come back. If the computer really is on at this point, but not asleep, and with a dimmed display, wouldn't the display snap back when I press the space bar and use the trackpad?

I'll call apple this weekend. No time right now.
 
hello. if the sleep light is off and the display is black, the backlight may be the problem. shine a bright light on the screen. do you see the desktop?
 
I'll try the flashlight if it happens again, but why would the screen sometimes go dim and not other times. When I restart, it's totally normal.

By the way, when draining the battery, is it neccesary to drain it until the machine shuts itself down, or just until it puts itself to sleep?
