NAME

       I8kctl, i8kfan - Utility to access SMM BIOS and DMI table information from Dell laptops

SYNTAX

       i8kctl [<command> [<args>]]
       i8kfan [<left> [<right>]]

DESCRIPTION

       The  i8kctl  utility  provides  a  command-line  interface to the i8k kernel module. When invoked without
       arguments the program reports the same information which can be read from the /proc/i8k file:

              1.  i8k format version
              2.  bios version
              3.  service tag (later 'machine id')
              4.  cpu temperature
              5.  left fan status
              6.  right fan status
              7.  left fan speed
              8.  right fan speed
              9.  ac power status
              10. fn buttons status

       The optional command argument can be used to select only one of the above items. Command can be: version,
       bios, id, temp, fan, speed, ac and fn. Examples:

              $ i8kctl
              1.0 A17 B5W123K 52 2 1 8040 6420 1 2

              $ i8kctl temp
              52

              $ i8kctl fan
              2 1

       The  fan  command  can  accept two optional parameters which specify the new fan state for left and right
       fans. The state parameter can be:

              0  turn the fan off
              1  set low speed
              2  set high speed
              -  don't change the state of this fan

       For example the command:

              $ i8kctl fan - 2

       sets the right fan to high speed and leaves the left unchanged.  It should be noted that if the i8kmon(1)
       daemon  is used to control the fans, setting the speed with i8kfan is pointless since the daemon override
       regularly the speed with its own value.

       Invoking i8kctl as i8kfan is the same as invoking the program with the fan option:

              $ i8kctl fan 1 2
              1 2

              $ i8kfan 1 2
              1 2
