I read the documentation for thinkpac-acpi. But I should say that
there were many things I did not understand.

I find that I can't change the fan levels:

root@skull-tp:~# echo 'level 1' > /proc/acpi/ibm/fan
root@skull-tp:~# cat /proc/acpi/ibm/fan
status:         enabled
speed:          0
level:          auto
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@skull-tp:~# echo 'level 7' > /proc/acpi/ibm/fan
root@skull-tp:~# cat /proc/acpi/ibm/fan
status:         enabled
speed:          0
level:          auto
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@skull-tp:~# echo disable > /proc/acpi/ibm/fan
root@skull-tp:~# cat /proc/acpi/ibm/fan
status:         enabled
speed:          0
level:          auto
commands:       level <level> (<level> is 0-7, auto, disengaged,
full-speed)
commands:       enable, disable
commands:       watchdog <timeout> (<timeout> is 0 (off), 1-120
(seconds))

Did I do anything wrong?
