Even though this has been reported and fixed it seems the fix has not gotten propagated for other models of the IBM Thinkpads. I have a IBM T60 and have been having the same issue for quite some time. First thought that it was something wrong with the hardware and then when I interrogated the logs I found the Critical temperature reached messages which took the system down.

I have manually corrected for this by doing the following: Created the file "/etc/modprobe.d/options" with the following line "options thinkpad_acpi fan_control=1". Then, after a reboot I was able to control the fan speed, setting it to automatic using "echo level full-speed > /proc/acpi/ibm/fan". root@mycomputer:~# cat /proc/acpi/ibm/fan status: enabled speed: 2908 level: disengaged commands: level <level> (<level> is 0-7, auto, disengaged, full-speed) commands: enable, disable commands: watchdog <timeout> (<timeout> is 0 (off), 1-120 (seconds)) root@mycomputer:~# cat /proc/acpi/ibm/fan status: enabled speed: 2908 level: disengaged commands: level <level> (<level> is 0-7, auto, disengaged, full-speed) commands: enable, disable commands: watchdog <timeout> (<timeout> is 0 (off), 1-120 (seconds)) root@mycomputer:~# cat /proc/acpi/ibm/fan status: enabled speed: 2908 level: disengaged commands: level <level> (<level> is 0-7, auto, disengaged, full-speed) commands: enable, disable commands: watchdog <timeout> (<timeout> is 0 (off), 1-120 (seconds)) root@mycomputer:~# cat /proc/acpi/ibm/fan status: enabled speed: 2908 level: disengaged commands: level <level> (<level> is 0-7, auto, disengaged, full-speed) commands: enable, disable commands: watchdog <timeout> (<timeout> is 0 (off), 1-120 (seconds)) After a minute or so I heard the fan speed kick up and now it is running consistantly @: root@mycomputer:~# cat /proc/acpi/ibm/fan status: enabled speed: 4692 level: disengaged commands: level <level> (<level> is 0-7, auto, disengaged, full-speed) commands: enable, disable commands: watchdog <timeout> (<timeout> is 0 (off), 1-120 (seconds)) root@mycomputer:~# cat /proc/acpi/ibm/fan status: enabled speed: 4693 level: disengaged commands: level <level> (<level> is 0-7, auto, disengaged, full-speed) commands: enable, disable commands: watchdog <timeout> (<timeout> is 0 (off), 1-120 (seconds)) Things seem to be better for the moment. Hope they can implement the fix for all IBM Thinkpad models soon. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/751689 Title: ThinkPads overheat due to slow fans when on 'auto' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/751689/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
