https://bugzilla.novell.com/show_bug.cgi?id=648719 https://bugzilla.novell.com/show_bug.cgi?id=648719#c1 --- Comment #1 from Mark Misulich 2010-10-23 17:58:20 UTC --- I have two other linux systems on this laptop. I have found that if the CPU temperature rises above ~60C and then the other system is shutdown, and the laptop is then booted into openSuse the fans will not come on. In order to get the fans to turn on, the CPU has to cool to some low temperature which I have not yet been able to determine before the computer is turned back on. The CPU has to cool to about room temperature ~20C before restarting the laptop to expect the fans to come on again at 55C as the CPU heats up in openSuse. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

With the new kernel on 11.1 the cooling fan operates without having to use the comment acpi_osi="Linux". But I don't think that works anyways, for the reasons that follow. I have two other linux distros on this laptop, xubuntu and elivecd. At the moment neither of those distros is useable on this laptop because the cooling fan doesn't operate with them. I have tried the comment acpi_osi="Linux" on both of them, and that doesn't work to get the fan running. The threads that I have been following to try to get the fan to work on those distros are: http://www.linuxquestions.org/questions/linux-laptop-and-netbook-25/fan-acpi... http://ubuntuforums.org/showthread.php?t=1036051 And a couple of other threads that are bookmarked on those systems, and not in opensuse which I am presently using. I have also tried to update the bios, which also had no effect after the update. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Hi, I installed originally opensuse 11.4 milestone 5 and have been updating it daily with zypper dup. The problem is a little different in the 11.4 version than in the 11.1 version. In the 11.4 version, the cooling fan doesn't ever come on to cool the laptop at any cpu temperature.

Ok, does a kernel from kernel:head work for you. 2.6.38-rc is reported to fix similar issues. http://download.opensuse.org/repositories/Kernel:/HEAD/openSUSE_Factory/ -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

If I then shut down the laptop and boot into either 11.3 or 11.4, the fans will come on immediately at the high temperature from before the shutdown, and they will stay on no matter what temperature the cpu is. They don't come on full blast, only at moderate speed. Eventually they cool the cpu down to about 48 degrees C. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

This fixes the problem if the right bits of the kernel are left in future versions. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
