Strange zzzzshshhshhhpffffpfffzzzz noise?
I got a PowerBook G4 17" 1,5 GHz last week.
I installed a SSD. Super fast, cool and silent.
Now I mention a silent zzzzshshhshhhpffffpfffzzzz noise when the power adapter is pluged in.
I can hear this noise when the PB is turned off with or without inserted battery.
On startup it dissappears and appears again when the OS has booted.
I could swear that this noise wasn't before. Its very silent, but I can hear it.
If you reduce the brighness there is another silent noise too.
The hardware check don't found anything.
Did you hear such noise on your PowerBooks
The DC-IN board?
Please help
