-- I've also noticed on the S900 that I've first worked on a high pitched whine while in the off position. Coming from the Power Supply. Replacing the PRAM battery which was defunct, changed nothing. Unplugging the power supply cord and the noise went away. Replacing the power Supply took care of the noise. This is the only S900 that I noticed this in. I've had several since. I believed the power supply was going bad so a replacement from Small Dog for $25 seemed in order. There have been several postings on the "Quadlist" about certain Performa models that develop a whine from the PS prior to a PS failure. It is a resistor I believe that is the major culprit. WN PS: I've worked in the power equipment industry for the last 35 years, so my hearing is definitely suspect. Ask my wife if you don't concurr. -- SuperMacs is sponsored by <http://lowendmac.com/> and...
