ibook Cannot wakeup from sleep
Help. This have been occuring quite frequently for my ibook.
Whenever i close my lid, my ibook will sleep. But sometimes, when i open the lid, the screen goes blank!! i know the system is still running cos I can feel the heat of the ibook and I can also listen to the sounds made by the CPU. I guess only the screen is not responding!
Does anybody have the same problem? Can anyone help me. I am running OS 10.2.1

I have had this happen (though not since Jag) ... it has been very infrequent, and I have no idea why.
I can shut down the computer by holding the power button down for several seconds. When it restarts, all is normal.
Anyone know WHY this happens ?
For me, the backlight somedimes doesn't come on, sometimes does. So I close/sleep my iBook and re-awaken it until the backlight comes on. Pretty annoying.
This problem seems to be happening more and more often. There are two long threads about it on the Apple Discussion boards. See:

Apple Certified Technicians are not allowed to work on the iBook. Therefore your only option is to send it in to Apple. Unless your iBook is still under warranty or covered by AppleCare, they charge about a $300 flat fee for this. The fee is the same regardless of whether they will have to replace a $10 cable or the entire laptop. My iBook is out of warranty, so I am getting ready to send it in for this repair in the next week or two. (I use it every day in law school, so the timing is difficult.) I'll report back.
What a major pain in the ass! I was expecting my iBook to be tougher than this.

anyone knows how long does apple usually takes to repair a laptop? one week???
<strong>I've had the same problem. As far as I can tell it's not software related. It's a problem with a display cable getting pinched/worn off in the hinge. Because of the damaged cable, the backlight of the LCD does not wake from sleep. Try to shine a bright light at your screen from the side when it doesn't wake up. You will see faint outlines of your open windows, dock, etc.

I don't think it is this problem in this case. I have that problem with the iBook waking from sleep, but it is not so much the backlight not coming on, as it is the screen completely coming on (so no outlines visible ever). Therefor, I am inclined to consider this a software related, or software-hardware-bridge related problem.
There is an issue with the screen as well, no denying that, but this is not the case here (at least in my opinion with my iBook).
Now, as far as I know, the waking from sleep automatically on opening the lid is hardware implemented in the iBook, so the problem must be there (with, e.g. the OS choking on these hardware commands).
I am not a apple tech, however, but i do think you're wrong, escher, in this case.

kopvlees: I hadn't heard of problems with the entire screen not working at all. I've only heard about backlight problems. But I'm not omniscient by any stretch of the imagination. From the description above, quoted below, it is difficult to tell whether stunned's problem is with the backlight only, the entire screen, or software only. Nobody knows who's right or wrong, and it doesn't really matter.

However, one thing that just ocurred to me is that Jaguar comes with 3 months of technical support.
stunned: Assuming you purchased Jaguar, call Apple and get your included "free" technical support. If it's software related, they should be able to fix it with you over the phone. If not, at least you will know before sending in your iBook.

I have this Matrix screensaver I use in 10.1.4 from Illuminex. If I close the lid while it's going, sometimes the display goes off but the computer isn't sleeping! The fan is still on etc! So the only option is restart, no keyboard commands fix it. Weird. I'm getting Jaguar, I have a feeling that will fix it. It's probably juts the screen saver's fault.
In this instance, the USB ports ceased to function so I couldn't use the keyboard etc to restore the screen.
this is a PowerBook, so i don't know if it's hardware related then. i'll try and see if i can see outlines next time it dies.
at this point it's up to twice a week.

<strong>oddly enough this started to happen to me as well. not sure what the deal is, but i'll look into this.

Be careful alcimedes. This occurence will happen more and more frequently. try not to meddle with your lid too much. What I do to solve this problem is never to close the lid.. Works like a charm.
Do update us about any discoveries. I dun like the sight of this blank screen one bit.
to go along with this cracked out sleep thing, there's a lighter band across the bottom of the entire screen. (about two inches tall)
this has been this way since i got it. i keep meaning to get it worked on, i just have to find a week when i won't need a computer at work. HA!
<strong>actually i'm kind of lucky. i just bought this machine (well, even luckier, work bought it) so it's still under warrenty.

haha. I face the same problem too. tats why my ibook is still not sent for repairs yet. luckily i got applecare.
i'm not positive that this is a software problem and not a hardware problem. there is zero display on the screen (checked w/a flashlight). i tried updating the ATI drivers to no avail, i think it's something to do with 10.2.2 i think. i'll have to see. hopefully 10.2.3 will take care of it.
i found that if i book the PowerBook to sleep before i close the lid, it will wake up just fine. however, if i shut the lid to put it to sleep, then i run into the problem where it can't wake up.
since trying this, i haven't run into the problem in days, i think this might be all that's broken in this case.
