stek1961 Posted June 10, 2007 Share Posted June 10, 2007 It's a mates, 12" iBook, symptoms are: 1. Boots, starts OSX (Panther) and is fine from 10-15 mins - then locks up. 2. One time it locked up with the top third of the screen dark. 3. It boots single user and its happy all day. 4. I can't boot from CD or DVD, sometimes getting nothing, sometimes showing a a bootable volume with option key held on boot. OSX Panther boot CD sort of boots to a no entry sign! 5. Diag disk boots and reports no errors. I've done the pram zapping, firmware resetting dodges, only thing I've not done is removed the ram or tried the PMU switch it has one. I suspect software, managed to repair permissions still locks up tho. The fact it;s happy in single user mode backs that up. But why no CD boot?

apowerr Posted June 10, 2007 Share Posted June 10, 2007 I have no idea as to why it wont boot from a CD, you'll have to wait for someone more knowledgeable to come along. I really wasnt impressed at all by the iBook. The MacBook is awesome! But the iBook, in any size with any proc...sucks. Link to comment Share on other sites More sharing options...
four! Posted June 11, 2007 Share Posted June 11, 2007 Here is the solution! It's not the Operating System or Firmware problem Its your GPU.... iBooks contacts on the logicboard for the GPU are really bad and they FAIL! Same thing happened on my iBook. The only way to fix it is to get a new laptop. Link to comment Share on other sites More sharing options...

stek1961 Posted June 14, 2007 Author Share Posted June 14, 2007 I read the link and it mentions the 'fan of death' - I hear no fan on this iBook, does it have one? If it does and it's not coming on then maybe I have a duff fan? Link to comment Share on other sites More sharing options...
