"If you choose "Longest Battery Life" or a Custom setting with Processor Performance set to "Reduced" in the Energy Saver preference panel, the sizzling sound quiets significantly so that it is practically inaudible in a quiet room. The PowerBook is quite tranquil this way (a pleasure to use), and I don't miss the processor performance since I'm generally just surfing at that time.
This tip seems to work from me (except that is not a good solution to loose processorspeed.
If you try this yourself it would be interesting to see if setting the Processor Performance to "Reduced"remove this noice at your powerbook too. "
i know it's just a bandaid...but ooohhh the silence
