I have 2 g-4 PowerBooks, a 667 and a 867 and the external sound in both stopped working. The sound is turned on and sound...

Find a friend with a mac and see if you can firewire/target connect your mac to his or hers. I have had Hd failures and sometimes have been able to save data. Replacing a hard drive is pretty simple in a G-4. I believe You just need that torq srewdriver to loosen the screws on the bottom of the computer. Take out the battery first.

I have no answer. I have 2 G-4 PowerBooks 667 and 1 just recently has lost internal sound and I have 1 G-4 867 that has lost sound now for 2 years. Sound works with earphone jacks on both computers. I wish apple would give a response why so many G-4 laptops have this problem Bounce
