It works well under Fedora 16 except that the fan is constantly on at high speed now. I don’t know if it’s because of something I’ve loaded, a setting I’ve modified, etc.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal> If I add the option “acpi=off” to the boot command then the fan stays at a reasonable rate.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal> Unfortunately this also slows down the CPU. My guess is that the CPU speed information is contained within the ACPI interface.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal> Does anyone have experience with controlling the fan on a Toshiba Tecra M4? I didn’t always have this problem so it’s either something I changed or something that was changed by an update somewhere along the way. Since I run the machine in various temperature environments and with different loads I thought the problem was just the CPU running hot but booting into a SLAX off USB showed the machine running normal – fan running slow, occasional speed up, then back to slow.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal> Any help, pointers, etc appreciated.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>---------------------------------------------------------------------------------------------------<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Steven Grunza<o:p></o:p></p><p class=MsoNormal>Products Engineer<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><b><i><span style='font-size:10.0pt;color:#548DD4'><img width=99 height=30 id="Picture_x0020_1" src="cid:image001.jpg@01CD2DE2.B3A7F480" alt="Description: ctdi_products_logo_smlcirc"><o:p></o:p></span></i></b></p><p class=MsoNormal><b><span style='font-size:10.0pt;color:#17365D'>CTDI | Products Division</span></b><span style='color:#1F497D'><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;color:gray'>1373 Enterprise Dr.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;color:gray'>West Chester, PA 19380<br>phone: 610-793-8527<br></span><span style='font-size:10.0pt;color:#76923C'>e-mail: <a href="mailto:jhomsey@ctdi.com|"><span style='color:blue'>sgrunza@ctdi.com</span></a></span><span style='font-size:10.0pt;color:#7F7F7F'> <a name=webProfileURL></a><o:p></o:p></span></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
