I also used the windows program http://sourceforge.net/projects/tp4xfancontrol/ to monitor fan speed while using windows 7. At idle the fan runs at around 3667 rpm while docked. While plugged in via AC or unplugged and not docked at idle it is at around 2280 rpm. I think either thinkpad_acpi thinks the laptop is always docked or levels 2-4 need worked on to have proper speeds.
When testing the levels I was using 2.6.28-15-generic with the latest thinkpad_acpi patch applied. -- thinkpad-acpi X200 Thinkpad fan fails to spin down . https://bugs.launchpad.net/bugs/380303 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
