Intermittent static noise goes away when asleep
Rebuilt this ibook about a year ago. I have intermittent static noise (sound, not visual). Sometimes it is loud. I cannot tell if it is coming from the speakers. Sometimes it will go away if I unplug the charger, sometimes not. Now the noise is pretty constant.
The iBook worked OK till last week when the hard drive seemed to go. Tried to reformat and reinstall OS, but kept freezing. The HD is about 2 years old, so I do not know if it's related. Will boot up fine with and external firewire drive. Also just installed another HD and it booted up fine, but the noise is still there. I guess it's the logic board. Any ideas?
