The problem I am having is noise that the computer is making when the firewire is plugged into it with the Firepod. When the power cord isn't plugged into the computer, the noise ceases but when I plug the firepod into it in any combination of the firewire outs, etc I get this noise. This noise stops for a second when I click on something or other wierd actions like that.
Anyone have a solution? -------------------- -Shawn

Hi guys
You may be experiencing the dreaded nap whine. My computer had the same thing: a high pitched whine that would change when I scrolled and moused over different things. The problem is caused by grounding apparently (or so I have heard) and how the mac uses the power to cycle the processors (again I have heard this as an explanation) At any rate the fix is to download and install the CHUD tools. Once installed there is a window that comes up and it has a checkbox that says nap. Click it to remove the arrow and that should get rid of the whine. I have done it since Oct 2003 and have experienced no ill results although the fans sometimes kick in for a bit when I uncheck it. go to this page and about 1/2 way down you'll see the link to download CHUD http://developer.apple.com/tools/performance/ |
