Have you got any device under /proc/acpi/fan? | Try to trigger on/off to that device. | Hi Wang, Yes, I get the following under /proc/acpi/fan: FAN1, FAN2, FAN3. I played triggering on off on fan. In fact, I could turn them on! :) I even could check that FAN2 and 3 are fan velocities as when I turned them on they did a much higher noise :) But unfortunately I couldn't turn them off :( I tried both echo off > /proc/acpi/fan/FAN1 and echo -n 0 > /proc/acpi/fan/FAN1, but they only turned it on. I mean, when I do echo off, it turns on. So I think that whatever I put is turning them on. What should I echo to turn them off? I think that if I learn how to turn it off by playing with acpi/fan it would be very cool!!
