iBook LCD backlight stays off after sleep :(
This is the strangest thing! Today, I woke up my iBook (May 2001 model) from sleep, and the backlight didn't come on.
I tried to restart with the power button, but that didn't work. So I did a hard reset. After a restart, the backlight still didn't come on, but I was able to restart by hitting the power button and then "R" (for restart). After the second restart, to my great relief, the backlight came back on.
Every time I've put the iBook to sleep and woken it up again since then, the backlight has NOT come on. When I restart, the backlight comes on 50% of the time and stays off for the other 50%.
I've had better luck putting the iBook to sleep without closing the lid, i.e. not moving the hinge at all. So the problem might be with the hinge.
There's already a thread about this problem <a href="http://forums.macnn.com/showthread.php?s=&threadid=56654" target="_blank">on MacNN</a>, but I thought people here would know more. Any ideas as to what is causing the backlight not to come on? This issue is seriously annoying! My iBook is only 15 months old. I don't want to replace it.

Anyway, the iBook problem, I've read about it with growing concern, have you got that squeaky hinge?

der Kopf: Interestingly enough, I didn't get a single reply on MacNN. But maybe that's because I resuscitated a 10 day old thread.
As for my iBook's hinge, it has always worked flawlessly, and still works fine. No squieaking. No excessive force required to open or close the lid.

alcimedes: Unfortunately, my 1-year warranty ran out almost four months ago and I didn't sign up for AppleCare. Fortunately, the iBook started waking ok again this morning. It's a complete mystery to me, but I'm not complaining.
Is it possible to sign up for AppleCare after your original warranty expires, if you bought your iBook through the Apple store? (I was able to sign up for AppleCare for my PowerBook 520c when the hinge broke several months after the original warranty expired. But that was through my Apple-authorized campus computer store in college.)

1. laptops. (or anything with a large LCD)
2. outdoor car stereo speakers. (i live in MN, the hot and cold can be really harsh)
best of luck to you with your iBook. if you get really brave, you can always take that sucker apart and have a look at the wires inside. that ought to tell you if there's something wrong with the wiring. just make sure you have a tech manual for the thing handy, it's a beast to get apart and back together. (i only had one extra screw when i did mine. )
It's definitely something with the hinge. Just now, I woke up my iBook and the backlight didn't come on. I closed the lid to put it back to sleep, reopened the lid to wake it, and voilÃ*, the backlight is on again.
I thought the iBook was supposed to be tough...

If anybody has ever had this done, I'd like to know, for my iBook is a horrible squeaker.
hardware is usually something where if you smack it the thing either breaks permanently or comes back full force (for a while)
are there any new display drivers for your iBook? have you checked apple's user forums to see if there's anything posted there? i haven't run into this yet, but i've yet to put 10.2 on my iBook either.

alcimedes: Good suggestion about Apple's User Forums. I haven't checked there yet, but will follow your advice and visit them. I'm probably going to drop by my local bricks-and-mortar Apple Store (Tyson's Corner) this weekend and will inquire there as well.
Since OS X 10.2 came with 3 months technical support by phone, I'll try calling there too before that warranty expires. After all, there is a slight chance this is a software issue related to 10.2.

I really should have gotten AppleCare for this iBook. But it's so damn expensive!
