Troubleshooting 10.2.4 problems on a new iBook System
I've got a new iBook 12" 800mhz that has had many weird problems since updating to 10.2.4. Eventually it would immediately sleep after startup and during startup, the screen would stay black until the actual osx blue screen progress bar appeared. During all this time neither the trackpad or keyboard would work. So once it did finish booting I couldn't do anything. A USB mouse allowed me to continue with the fixing. I have since fixed it by doing several things .. any and all of which probably had some affect.
  1. Remove battery with machine shut down. Leave A/C power plugged in. With the battery attached I could not see the screen.
  2. Reset PowerManager. On my iBook that is done by holding command-option-shift-powerkey.
  3. Start machine with powerbutton and hold down option-command-p-r and let it reboot several times.
  4. Start machine while holding option-command-O-F to boot into open firmware.
  5. Type reset-nvram and hit return.
  6. Type reset-all and hit return; the machine will now reboot.
  7. When machine comes up, run Disk Utility and Repair File Permissions.
  8. Shut Down.
  9. Replace battery.
  10. Restart.
From what I can tell, removing the battery and repairing file permissions is what actually made the difference. It has also been suggested to reinstall the OSX 10.2.4 update using the standalone combined updater since this was originally updated using Software Update from System Preferences. I have not done this since I believe in "If it's not broke, don't fix it!" Hope this helps someone.

Troubleshooting 10.2.4 problems on a new iBook

I'm betting you will eventually have to have the logic board replaced. I had very similar symptoms and applied solutions almost exactly like yours, with limited success. In the end, I had to send it back to Apple. Sent it on a Tuesday, it was returned on a Thursday with a new logic board, and it has been a champ ever since. Another user with an identical iBook had the same problem and also sent hers in for warranty repair.

So keep your backups fresh...

Well, guess what? You are right. After working without incident for a whole day it returned to it's flaky behavior. I sent it back to Apple today.

And I thought I was clever for fixing it ;-)

Did you try "zapping" the nvram? (Pull the battery, pull the plug, hold in the power button and reset button for several seconds)

Thanks a lot. Works so far. I have a deadline to meet and your tip was
really precious. Might send my ibook to apple though, while it is still
under the warrantry.

Cheers,

Janne

Few more comments. I am running 10.2.5 on the new 14 inch
iBook. The fix seemed to be very temporary and my screen
stays now permanently blank. It seems to be the time to send
my machine to Apple.
