iBook woes.

http://www.applefritter.com/node/10193

Hah! So it's really not just me. I'm absurdly tempted to just take it apart and try some of the suggestions (tightening screws, finding the GPU and adding a shim of some sort..). 'cause if that fixes the problem...... Meh. I don't have a week to wait on Apple to repair the machine.

Most interesting was the post by "iantm",
As a service technician who oversees a 2000 unit deployment of 1ghz 12" iBook G4's, the video chipset failing is an unusual failure path (1 every two months). Another factor in logic board failure that I've come across has been heavy use. Units that see a lot of heavy use in settings other than on a desk have a higher failure path than units who only see desk use (while still being transported from place to place.

The primary point of failure I've observed with the iBook G4 logic boards has been where the unit fails POST, won't chime, spins the fan at full speed, and provides no backlight or video. Once at this point, nothing resolves the issue. Resetting the PMU doesn't resolve the matter, the suggestions with the video chip also don't help, which leads me to believe that the point of failure is somewhere else.


Which is almost exactly like my problem, with the exception that I do get backlight, but no video and the fans spin at full speed.

And the iBook does get put through heavy use.

Actually, I do have the Apple Service Manuals... so technically, I do have the instructions to take the damn thing apart, and they shouldn't be able to tell the difference.......... maybe? o.O
