I have a 500MHz iBook G3 with 192MB RAM and a 10GB HD (has 10.3 installed). It worked fine (sort of) a few days ago. I had to take it apart to install a new inverter cable because the old one went bad. Now, I go to power it on and it almost fully boots but goes immediately to sleep. I can make it wake up by using the keyboard but if I try to make the dialog box for the time/ date error thing go away by hitting enter nothing happens. It will go back to sleep right away. The trackpad isn't working now. It might be disconnected or the cable broke.
Can anyone help me with my problem so i can use this computer again.

All I can say is I had a similar problem w/ my ibook g3. It would go to sleep every 15 min but I don't know why and I sent it in to applecare cause I didn't want to void warranty by opening it up. They sent it back and it worked fine. The case description said power/battery related malfunction.

Sorry I could not be of more help.

I seem to have a similar problem if you solve yours get in touch with me , I'll do the same: here is my problem post


I'm having a problem I would like to run by you. I have a Ibook G4 /1.2 ghz/ 12" screen. It 's keyboard and trackpad don't work. I can use the ibook with an external usb keyboard and mouse. The thing is if I start from a ubuntu install disk everything is fine. And I would be happy with that, but i don't know how to set up the modem for Ubuntu. Any way further when I put in the osx hardware test disk and test it . it says everything is fine and while I'm still booted from that disk the trackpad and keyboard work just fine , but as soon as I reboot to OS X they go back to not working. I've tried booting from an external firewire drive with the same results. I have also since tried to do some combo updates and when I try to go from any comboupdate as in 10.4.6 through 10.4.9 the keyboard and tracpad work fine but a whole new issue comes up immediately. After the update restarts the ibook I can see keyboard and trackpad are working but when the system reaches full reboot within 20 seconds it goes to sleep. I can wake it just for a split second but then it proceeds to go back to sleep. I have done many complete installs trying for a fix so there isn't any important info to loose. Right now i'm running it on 10.4.1 with an external keyboard and mouse. The previous owner said it started this after he fell with it in his backpack, but it doesn't seem to me to be a mechanical issue. Just thought you might have some ideas for me to try??? If you could try to send me a reply to my email larrybdl@localnet.com

I just had almost the exact same problem with an iBook that I believe had been dropped. The dead give away was in system profiler - at the very bottom look to see if it says "Clamshell Closed: Yes" if the lid is obviously open and it thinks it's closed it will cause a whole host of problems.

Reed Switch details:
http://listserver.themacintoshguy.co...st/010663.html

A reed switch is a tiny glass tube with two metal reeds inside that
almost touch. Normally, current cannot pass through the switch because
the metal reeds are separated by a small gap. When a magnet is brought
near the switch, the reeds are drawn together toward one side of the
tube. They make contact, and the switch turns on.
(Credit due to Justin Granger at smalldog.com posted via link above)

In my case the glass tube around the reed switch was shattered and causing an electrical short...I actually got a tiny shock from current still in it after it was taken it out completely. Unlike other information I found online, my reed switch was located on the bottom casing around the CD-Rom drive/under the keyboard (so I didn't need to take the display casing completely apart). Once the iBook was all back together it worked flawlessly, backlight, keyboard and touchpad were all working again as expected. The only downside is, the iBook will never go to sleep when the lid is closed b/c it won't know any better...but I don't care it was a free iBook all I had to do was get it working and the reed switch is not required for operation otherwise.

I originally came to this forum for help before I figured it out and was going to post my troubleshooting thus far, but after concluding the reed switch was the problem I figured I'd wait until I knew I was right before posting my original post details are included at the very bottom, hopefully they'll help someone else diagnose this problem as before I figured it out, I didn't even know what a reed switch was.

If you are comfortable taking apart your iBook and it is already out of warranty proceed with caution and Good Luck!

If your iBook is still under warranty or you can't afford a new one if the repair ends up breaking it more, leave it to someone that has experience or contact Apple/a professional...unfortunately the reed switch is likely an expensive repair to let Apple/Other certified repair place do b/c of the labor even though the part alone can be purchased for somewhere between $15-$100 depending where you get it or it can just taken out. Please do your own price/risk research before making a decision as this is merely my opinion and I do not work for nor am permitted to speak for Apple or what they actually charge for repairs.

Original troubleshooting/intended post:

sounds pretty similar to the problem Iím havingÖ.got this laptop from work as a challenge to ďplay withĒ so I donít exactly know the whole history of it, but itís rumored to have been dropped, but Iím having trouble really isolating the hardware problem from the software (it acts like both). When I first got it, it would boot up, but show nothing on the screen/no back light until the blue screen before login, could login and have just enough time to open system prefs and then it would go to sleep (30sec - 1min or so Iím guessing) after it goes to sleep I can wake it up with option or command (have to hold it down for a bit) but when it wakes up I have no backlight, and the keyboard doesnít work (but the iBook will work with an external monitor if the monitor was connected during startup) with the external monitor I can continue controlling the system for about 30 seconds at a time via the trackpad mouse but I have to use a USB keyboard (which is still hot swappable as it should be unlike the monitor) there is nothing I can hold down or do that Iíve discovered so far to keep the iBook from going back to sleep making troubleshooting quite slow and tedious.

- Found that keyboard & backlight physically work fine, can clear PRAM on startup and use option startup or c to boot to CD/DVD and run Apple Hardware test (which came up clean)

- Can clear nvram in open firmware, and iBook stays on for hours without going to sleep and backlight and keyboard physically work fine.

- After booting to random 10.4.2 disk that Iíve used several times in the past it didnít recognize the lcd so had to use external monitor, but I could successfully install 10.4.2 after also plugging in a USB mouse (it demanded it and halted until I plugged one in) full format install probably rules out any HDD physical damage since Iíve formatted it 4-5 times by now on boot up after install it didnít recognize the iBook lcd at all (like not even in system profiler) so had to use external monitor, USB mouse and also USB keyboard after finding iBook didnít recognize itís own keyboard and still not the trackpadÖ.but the sleeping problem was gone YAY! Except a laptop that canít work ďundockedĒ is useless.

- Found some original iBook G4 10.4.2 and 10.3.7 restore disks we had laying around at work, it treated the panther set like my generic tiger disk so I didnít bother to install and judging by the serial number this was made 9th week 2006 so it would have shipped with tiger anywayÖbooted up to the tiger restore and iBook seemed quite happy, I had backlight, and trackpad but no keyboard, after running updates and upgrading to 10.4.10 it was back to its original tricks Ė no backlight until blue screen, keyboard an mouse work until it goes to sleep about 30 seconds after login.

Not sure if you're still looking for help on this 3 months later...

Can you boot it up on an external monitor and open up terminal long enough to type in system_profiler

and then copy and paste that to a text file (preferably on a thumb drive/external source) before you lose control/video?

Your system might be slightly different from mine and the hardware details might help provide another clue. And I'm interested what the system believes the state of the clamshell to be.

Does the problem exist on a base installation and/or only after running Software Update as mine did?

you might try .. booting to a linux live cd for the ppc if the keyboard and trackpad work in there but still no back light .. most likely the Hall/effect sensor / reed switch is bad.. just removing it will not help . the logicboard is not looking for a open when the clamshell is closed .. its looking for a short in the circuit or a voltage of some type .. and for the life of me I can't find out how to fool the circuit either.
PowerBook reed switch stuck OS X reporting Clamshell: Closed

Good luck
