It could be a fan. My PB is pretty cold now and I don't hear buzzing. I floated the fan idea with the repair people when I had it repaired last, but they focused on the HD right away. After the replacement I had no fan noise for a couple of months, which makes me think they were right. Or could it be something defect in the HD that causes it to overheat and activate the fan?</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>I thought HD replacement on the newer powerbooks was difficult. I used to do it all the time on my Pismo, but I thought it was major surgery on a PB.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>Jim</DIV><DIV><BR><DIV class="AppleOriginalContents"><DIV>On 5-Mar-06, at 11:19 PM, Dennis Fazio wrote:</DIV><BR class="Apple-interchange-newline"><BLOCKQUOTE type="cite"><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; min-height: 14px; "><BR></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">On Mar 5, 2006, at 4:14 PM, Jim Freeman wrote:</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; min-height: 14px; "><BR></DIV> <BLOCKQUOTE type="cite"><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">When I lift the computer and turn it at a particular angle, there is a buzzing sound like a fast moving part rubbing somewhere.</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; min-height: 14px; "><BR></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">Am I just unlucky, with two hard drives failing in a row? or is the hard drive failure a symptom of something else?</DIV> </BLOCKQUOTE><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; min-height: 14px; "><BR></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">It could be a fan, so verify it is not coincidental with the fans going on.
