With this fix the fan is not constant blowing on linux. We have to fix the temparature values to a new DSDT file and let the kernel use it. It realy works!! ** Copy the binary DSDT to your home directory: # cat /proc/acpi/dsdt > /home/jim/dsdt.dat ** Disassemble the DSDT file (you just copied) /usr/bin/iasl -d /home/jim/dsdt.dat this tool produces a text file called: dsdt.dsl ** Edit the dsdt.dsl file and change the temperature values. You can find then near row 14498 and change them to these values: Name(xxx, Package(0x6) { 0x64, 0x4b, 0x32, 0x1E, 0x14, 0x0 }) or when it is still not enough, you can use these: Name(xxx, Package(0x6) { 0x64, 0x4b, 0x23, 0x1E, 0x14, 0x0 }) ** Compile the changed dsdt.dsl ./iasl -tc dsdt.dsl this tool is producing a dsdt.aml. This file is going to be used by the kernel for the better values. For that you need a scipt. On OpenSuse 11.1 i needed to install the kernel sources. ** Install the kerne...
